Introduction This document provides information about the NumonyxTM AxcellTM P33-65nm Flash memory and describes its features, operations, and specifications. P33-65nm is the latest generation of NumonyxTM AxcellTM P33 Flash memory to the embedded flash market segment, offered in 64-Mbit up through 2-Gbit. This document covers specifically 512-Mbit, 1-Gbit, 2-Gbit product information. Benefits include more density in less space, high-speed interface NOR device, and support for code and data storage. Features include high-performance synchronous-burst read mode, dramatical improvement in buffer program time through larger buffer size, fast asynchronous access times, low power, flexible security options, and two industry-standard package choices. P33-65nm is manufactured using NumonyxTM 65nm process technology. 1.2 Overview The P33-65nm device provides high performance on a 16-bit data bus. Individually erasable memory blocks are sized for optimum code and data storage. Upon initial power-up or return from reset, the device defaults to asynchronous page-mode read. Configuring the RCR(Read Configuration Register) enables synchronous burst-mode reads. In synchronous burst mode, output data is synchronized with a user-supplied clock signal. A WAIT signal provides an easy CPU-to-flash memory synchronization. In addition to the enhanced architecture and interface, the device incorporates technology that enables fast buffer program and erase operations. The device features a 512-word buffer to enable optimum programming performance, which can improve system programming throughput time significantly to 1.46MByte/s. Designed for low-voltage systems, P33-65nm device supports read operations with VCC at 3.0V, and erase and program operations with VPP at 3.0V or 9.0V. Buffered Enhanced Factory Programming provides the fastest flash array programming performance with VPP at 9.0V, which increases factory throughput. With VPP at 3.0V, VCC and VPP can be tied together for a simple, ultra low power design. In addition to voltage flexibility, a dedicated VPP connection provides complete data protection when VPP VPPLK. The Command User Interface is the interface between the system processor and all internal operations of the device. An internal Write State Machine automatically executes the algorithms and timings necessary for block erase and program. A Status Register indicates erase or program completion and any errors that may have occurred. A device command sequence invokes program and erase automation. Each erase operation erases one block. The Erase Suspend feature allows system software to pause an erase cycle to read or program data in another block. Program Suspend allows system software to pause programming to read other locations. The P33-65nm OTP register allows unique flash device identification that can be used to increase system security. The individual Block Lock feature provides zero-latency block locking and unlocking. The P33-65nm device adds enhanced protection via Password Access; this new feature allows write and/or read access protection of user-defined blocks. In addition, the P33-65nm device also has backward compatible One-Time Programmable (OTP) permanent block locking security feature. Datasheet 5 Feb 2010 Order Number:208043-04 P33-65nm 1.3 Virtual Chip Enable Description (2-Gbit) The P33-65nm device employs a Virtual Chip Enable which combines two 1-Gbit dies with a common chip enable, CE# for Easy BGA and TSOP packages. Address A27 is then used to select between the die pair with CE# asserted, depending upon the package option used. When chip enable is asserted and A27 is low (VIL), the bottom die is selected; when chip enable is asserted and A27 is high (VIH), the top die is selected.

Note: The virtual selection of the Top 1-Gbit die in the dual-die 2-Gbit configuration is accomplished by setting A27 high (VIH). DQ[15:0] Input/ Output DATA INPUT/OUTPUTS: Inputs data and commands during write cycles; outputs data during reads of memory, status register, OTP register, and read configuration register. Data balls/pins float when the CE# or OE# are deasserted. Data is internally latched during writes. Input ADDRESS VALID: Active low input. During synchronous read operations, addresses are latched on the rising edge of ADV#, or on the next valid CLK edge with ADV# low, whichever occurs first. In asynchronous mode, the address is latched when ADV# going high or continuously flows through if ADV# is held low. WARNING: Designs not using ADV# must tie it to VSS to allow addresses to flow through. CE# Input CHIP ENABLE: Active low input. CE# low selects the associated flash memory die. When asserted, flash internal control logic, input buffers, decoders, and sense amplifiers are active. When deasserted, the associated flash die is deselected, power is reduced to standby levels, data and WAIT outputs are placed in high-Z state. WARNING: Chip Enable must be high when device is not in use. CLK Input CLOCK: Synchronizes the device with the system's bus frequency in synchronous-read mode. During synchronous read operations, addresses are latched on the rising edge of ADV#, or on the next valid CLK edge with ADV# low, whichever occurs first. WARNING: Designs not using CLK for synchronous read mode must tie it to VCCQ or VSS. OE# Input OUTPUT ENABLE: Active low input. OE# low enables the device's output data buffers during read cycles. OE# high places the data outputs and WAIT in High-Z. RST# Input RESET: Active low input. RST# resets internal automation and inhibits write operations. This provides data protection during power transitions. RST# high enables normal operation. Exit from reset places the device in asynchronous read array mode. ADV# WAIT Output WAIT: Indicates data valid in synchronous array or non-array burst reads. RCR.10, (WT) determines its polarity when asserted. WAIT's active output is VOL or VOH when CE# and OE# are VIL. WAIT is high-Z if CE# or OE# is VIH. * In synchronous array or non-array read modes, WAIT indicates invalid data when asserted and valid data when deasserted. * In asynchronous page mode, and all write modes, WAIT is deasserted. WE# Input WRITE ENABLE: Active low input. WE# controls writes to the device. Address and data are latched on the rising edge of WE#. WP# Input WRITE PROTECT: Active low input. WP# low enables the lock-down mechanism. Blocks in lockdown cannot be unlocked with the Unlock command. WP# high overrides the lock-down function enabling blocks to be erased or programmed using software commands. VPP Power/ Input ERASE AND PROGRAM POWER: A valid voltage on this pin allows erasing or programming. Memory contents cannot be altered when VPP VPPLK. Block erase and program at invalid VPP voltages should not be attempted. Set VPP = VPPL for in-system program and erase operations. To accommodate resistor or diode drops from the system supply, the VIH level of VPP can be as low as VPPL min. VPP must remain above VPPL min to perform in-system flash modification. VPP may be 0 V during read operations. VPPH can be applied to array blocks for 1000 cycles maximum. VPP can be connected to 9 V for a cumulative total not to exceed 80 hours. Extended use of this pin at 9 V may reduce block cycling capability. VCC Power DEVICE CORE POWER SUPPLY: Core (logic) source voltage. Writes to the flash array are inhibited when VCC VLKO. Operations at invalid VCC voltages should not be attempted. VCCQ Power OUTPUT POWER SUPPLY: Output-driver source voltage. VSS Power GROUND: Connect to system ground. Do not float any VSS connection.

Feb 2010 Order Number:208043-04 P33-65nm 5.0 Bus Operations CE# low and RST# high enable device read operations. The device internally decodes upper address inputs to determine the accessed block. ADV# low opens the internal address latches. OE# low activates the outputs and gates selected data onto the I/O bus. Bus cycles to/from the P33-65nm device conform to standard microprocessor bus operations. Table 5, "Bus Operations Summary" summarizes the bus operations and the logic levels that must be applied to the device control signal inputs.

Refer to the Table 7, "Command Bus Cycles" on page 21 for valid DQ[15:0] during a write operation. 2. X = Don't Care (H or L). 3. RST# must be at VSS 0.2V to meet the maximum specified power-down current. 5.1 Read - Asynchronous Mode To perform an asynchronous page or single word read, an address is driven onto the address bus, and CE# is asserted. ADV# can be driven high to latch the address, or it must be held low throughout the read cycle. WE# and RST# must already have been deasserted. WAIT is set to a deasserted state during asynchronous page mode and single word mode as determined by RCR.10. CLK is not used for asynchronous pagemode reads, and is ignored. After OE# is asserted, the data is driven onto DQ[15:0] after an initial access time tAVQV or tGLQV delay. (See Table 25, "AC Read Specifications -" on page 52). If only asynchronous reads are to be performed, CLK should be tied to a valid VIH level, WAIT signal can be floated and ADV# must be tied to ground. In asynchronous page mode, sixteen data words are "sensed" simultaneously from the flash memory array and loaded into an internal page buffer. The buffer word corresponding to the initial address on the Address bus is driven onto DQ[15:0] after the initial access delay. The lowest four address bits determine which word of the 16-word page is output from the data buffer at any given time. Refer to the following waveforms for more detailed information:Figure 18, "Asynchronous Single-Word Read (ADV# Low)" on page 53, and Figure 19, "Asynchronous Single-Word Read (ADV# Latch)" on page 54, and Figure 20, "Asynchronous Page-Mode Read Timing" on page 54. 5.2 Read - Synchronous Mode To perform a synchronous burst read on array or non-array, an initial address is driven onto the address bus, and CE# is asserted. WE# and RST# must already have been deasserted. ADV# is asserted, and then deasserted to latch the address. Alternately, Datasheet 16 Feb 2010 Order Number: 208043-04 P33-65nm ADV# can remain asserted throughout the burst access, in which case the address is latched on the next valid CLK edge while ADV# is asserted. Once OE# is asserted, the the first word is driven onto DQ[15:0] on the next valid CLK edge after initial access latency delay (see Section 11.2.2, "Latency Count (RCR[14:11])" on page 36). Subsequent data is output on valid CLK edges following a minimum delay Tchqv (see Table 25, "AC Read Specifications -" on page 52). However, for a synchronous non-array read, the same word of data will be output on successive clock edges until the burst length requirements are satisfied. The WAIT signal indicates data valid when the device is operating in synchronous mode (RCR.15=0). The WAIT signal is only "deasserted" when data is valid on the bus. When the device is operating in synchronous non-array read mode, such as read status, read ID, or read query, the WAIT signal is also "deasserted" when data is valid on the bus. WAIT behavior during synchronous non-array reads at the end of word line works correctly only on the first data access. Refer to the following waveforms for more detailed information: Figure 21, "Synchronous Single-Word Array or Non-array Read Timing" on page 55, and Figure 22, "Continuous Burst Read, showing an Output Delay Timing" on page 55, and Figure 23, "Synchronous Burst-Mode Four-Word Read Timing" on page 56. 5.3 Write To perform a write operation, both CE# and WE# are asserted while RST# and OE# are deasserted. During a write operation, address and data are latched on the rising edge of WE# or CE#, whichever occurs first. Table 7, "Command Bus Cycles" on page 21 shows the bus cycle sequence for each of the supported device commands, while Table 6, "Command Codes and Definitions" on page 19 describes each command. See Table 26, "AC Write Specifications" on page 56 for signal-timing details. When the device is operating in write operations, WAIT is set to a deasserted state as determined by RCR.10. Note: Write operations with invalid VCC and/or VPP voltages can produce spurious results and should not be attempted. 5.4 Output Disable When OE# is deasserted, device outputs DQ[15:0] are disabled and placed in a highimpedance (High-Z) state, WAIT is also placed in High-Z. 5.5 Standby When CE# is deasserted the device is deselected and placed in standby, substantially reducing power consumption. In standby, the data outputs are placed in High-Z, independent of the level placed on OE#. Standby current, ICCS, is the average current measured over any 5 ms time interval, 5 s after CE# is deasserted. When the device is deselected (while CE# is deasserted) during a program or erase operation, it continues to consume active power until the program or erase operation is completed. Datasheet 17 Feb 2010 Order Number:208043-04 P33-65nm 5.6 Reset As with any automated device, it is important to assert RST# when the system is reset. When the system comes out of reset, the system processor attempts to read from the flash memory if it is the system boot device. If a CPU reset occurs with no flash memory reset, improper CPU initialization may occur because the flash memory may be providing status information rather than array data. Flash memory devices from NumonyxTM allow proper CPU initialization following a system reset through the use of the RST# input. After initial power-up or reset, the device defaults to asynchronous Read Array mode, and the Status Register is set to 0x80. When RST# is driven low (RST# asserted), the flash device enters reset mode. Then all internal circuits are de-energized, and the output drivers are placed in High-Z. If RST# is asserted during a program or erase operation, the operation is terminated and the memory contents at the aborted location (for a program) or block (for an erase) are no longer valid. A device reset also clears the Status Register. See Table 18, "Power and Reset" on page 44 for RST# timing detail. When RST# is driven high (RST# deasserted), a minimum wait is required before the flash device is able to perform normal operations. Please consider Tphqv (R5) and Tphwl (W1) during system design. see Table 25, "AC Read Specifications -" on page 52. and Section 26, "AC Write Specifications" on page 56. After this wake-up interval passes, normal operation is ready for execution. Datasheet 18 Feb 2010 Order Number: 208043-04 P33-65nm 6.0 Command Set 6.1 Device Command Codes The flash Command User Interface (CUI) provides control of all read, write, and erase operations. The on-chip WSM manages all block-erase and word-program algorithms. Device commands are written to the CUI to control all flash memory device operations. The CUI does not occupy an addressable memory location; it is the mechanism through which the flash device is controlled. Table 6 shows valid device command codes and descriptions. Table 6: Mode Read Write Command Codes and Definitions (Sheet 1 of 2) Code Device Mode 0xFF Read Array Places the device in Read Array mode. Array data is output on DQ[15:0]. 0x70 Read Status Register Places the device in Read Status Register mode. The device enters this mode after a program or erase command is issued. SR data is output on DQ[7:0]. 0x90 Read Device ID or Read Configuration Register(RCR) Places device in Read Device Identifier mode. Subsequent reads output manufacturer/device codes, Configuration Register data, Block Lock status, or OTP register data on DQ[15:0]. 0x98 Read CFI Places the device in Read Query mode. Subsequent reads output Common Flash Interface information on DQ[7:0]. 0x50 Clear Status Register The WSM can only set SR error bits. The Clear Status Register command is used to clear the SR error bits. 0x40 Word Program Setup First cycle of a 2-cycle programming command; prepares the CUI for a write operation. On the next write cycle, the address and data are latched and the WSM executes the programming algorithm at the addressed location. During program operations, the device responds only to Read Status Register and Program Suspend commands. CE# or OE# must be toggled to update the Status Register in asynchronous read. CE# or ADV# must be toggled to update the SR Data for synchronous Non-array reads. The Read Array command must be issued to read array data after programming has finished. 0xE8 Buffered Program This command loads a variable number of words up to the buffer size of 512 words onto the program buffer. 0xD0 Buffered Program Confirm The confirm command is issued after the data streaming for writing into the buffer is done. This instructs the WSM to perform the Buffered Program algorithm, writing the data from the buffer to the flash memory array. 0x80 BEFP Setup First cycle of a 2-cycle command; initiates the BEFP mode. The CUI then waits for the BEFP Confirm command, 0xD0, that initiates the BEFP algorithm. All other commands are ignored when BEFP mode begins. 0xD0 BEFP Confirm If the previous command was BEFP Setup (0x80), the CUI latches the address and data, and prepares the device for BEFP mode. Block Erase Setup First cycle of a 2-cycle command; prepares the CUI for a block-erase operation. The WSM performs the erase algorithm on the block addressed by the Erase Confirm command. If the next command is not the Erase Confirm (0xD0) command, the CUI sets Status Register bits SR[5,4], and places the device in Read Status Register mode. Block Erase Confirm If the first command was Block Erase Setup (0x20), the CUI latches the address and data, and the WSM erases the addressed block. During blockerase operations, the device responds only to Read Status Register and Erase Suspend commands. CE# or OE# must be toggled to update the Status Register in asynchronous read. CE# or ADV# must be toggled to update the SR Data for synchronous Non-array reads. 0x20 Erase 0xD0 Datasheet 19 Description Feb 2010 Order Number:208043-04 P33-65nm Table 6: Command Codes and Definitions (Sheet 2 of 2) Mode Code 0xB0 Program or Erase Suspend 0xD0 Suspend Resume This command issued to any device address resumes the suspended program or block-erase operation. 0x60 Block lock Setup First cycle of a 2-cycle command; prepares the CUI for block lock configuration changes. If the next command is not Block Lock (0x01), Block Unlock (0xD0), or Block Lock-Down (0x2F), the CUI sets SR[5,4], indicating a command sequence error. 0x01 Block lock If the previous command was Block Lock Setup (0x60), the addressed block is locked. 0xD0 Block Unlock If the previous command was Block Lock Setup (0x60), the addressed block is unlocked. If the addressed block is in a lock-down state, the operation has no effect. 0x2F Block Lock-Down If the previous command was Block Lock Setup (0x60), the addressed block is locked down. 0xC0 OTP Register or Lock Register program setup First cycle of a 2-cycle command; prepares the device for a OTP register or Lock Register program operation. The second cycle latches the register address and data, and starts the programming algorithm to program data the the OTP array. 0x60 Read Configuration Register Setup First cycle of a 2-cycle command; prepares the CUI for device read configuration. If the Set Read Configuration Register command (0x03) is not the next command, the CUI sets Status Register bits SR[5,4], indicating a command sequence error. 0x03 Read Configuration Register If the previous command was Read Configuration Register Setup (0x60), the CUI latches the address and writes A[16:1] to the Read Configuration Register. Following a Configure RCR command, subsequent read operations access array data. 0xBC Block Blank Check First cycle of a 2-cycle command; initiates the Blank Check operation on a array block. 0xD0 Block Blank Check Confirm Second cycle of blank check command sequence; it latches the block address and executes blank check on the main array block. 0xEB Extended Function Interface command This command is used in extended function interface. first cycle of a multiplecycle command second cycle is a Sub-Op-Code, the data written on third cycle is one less than the word count; the allowable value on this cycle are 0 through 511. The subsequent cycles load data words into the program buffer at a specified address until word count is achieved. Configuration Blank check EFI 6.2 Description This command issued to any device address initiates a suspend of the currently-executing program or block erase operation. The Status Register indicates successful suspend operation by setting either SR.2 (program suspended) or SR.6 (erase suspended), along with SR.7 (ready). The WSM remains in the suspend mode regardless of control signal states (except for RST# asserted). Suspend Protection Device Mode Device Command Bus Cycles Device operations are initiated by writing specific device commands to the CUI. See Table 7, "Command Bus Cycles" on page 21. Several commands are used to modify array data including Word Program and Block Erase commands. Writing either command to the CUI initiates a sequence of internally-timed functions that culminate in the completion of the requested task. However, the operation can be aborted by either asserting RST# or by issuing an appropriate suspend command.

Upon power-up or after a reset, the device defaults to Read Array mode. To change the read state, the appropriate read command must be written to the device (see Section 6.2, "Device Command Bus Cycles" on page 20). The following sections describe read-mode operations in detail. In order to enable synchronous burst reads, the RCR must be configured. Please see Section 11.2, "Read Configuration Register (RCR)" on page 35 for RCR detail. Please refer to Section 5.1, "Read - Asynchronous Mode" on page 16 and Section 5.2, "Read Synchronous Mode" on page 16 for bus operation detail. See Section 25, "AC Read Specifications -" on page 52 for timing specification. 7.1 Read Array Following a device power-up or reset, the device is set to Read Array mode. However, to perform array reads after any other device operation (e.g. write operation), the Read Array command must be issued in order to read from the flash memory array. Please refer to Section 5.1, "Read - Asynchronous Mode" on page 16 and Section 5.2, "Read Synchronous Mode" on page 16 for bus operation detail. See Section 25, "AC Read Specifications -" on page 52 for timing specification. 7.2 Read Device Identifier The Read Device Identifier command instructs the device to output manufacturer code, device identifier code, block-lock status, OTP register data, or configuration register data (see Section 6.2, "Device Command Bus Cycles" on page 20 for details on issuing the Read Device Identifier command). Table 8, "Device Identifier Information" on page 22 and Table 9, "Device ID codes" on page 23 show the address offsets and data values for this device.

Each die within the stack can be identified by the ID codes. 7.3 Read CFI The Read CFI command instructs the device to output Common Flash Interface data when read. See Section A.1, "Common Flash Interface" on page 62 for detailed information. 7.4 Read Status Register To read the Status Register, issue the Read Status Register command at any address. Status Register information is available to which the Read Status Register, Word Program, or Block Erase command was issued. SRD is automatically made available following a Word Program, Block Erase, or Block Lock command sequence. Reads from the device after any of these command sequences outputs the device's status until another valid command is written (e.g. the Read Array command). The Status Register is read using single asynchronous-mode or synchronous burst mode reads. SRD is output on DQ[7:0], while 0x00 is output on DQ[15:8]. In asynchronous mode the falling edge of OE#, or CE# (whichever occurs first) updates and latches the Status Register contents. However, when reading the Status Register in synchronous burst mode, CE# or ADV# must be toggled to update SRD. The Device Write Status bit (SR.7) provides overall status of the device. SR[6:1] present status and error information about the program, erase, suspend, VPP, and block-locked operations. See Table 12, "Status Register Description" on page 34 for the description of the status register. 7.5 Clear Status Register The Clear Status Register command clears the status register. It functions independent of VPP. The WSM sets and clears SR.7, but it sets bits SR[5:3,1] without clearing them. The Status Register should be cleared before starting a command sequence to avoid any ambiguity. A device reset also clears the Status Register. Datasheet 23 Feb 2010 Order Number:208043-04 P33-65nm 8.0 Program Operation The device supports three programming methods: Word Programming (40h or 10h), Buffered Programming (E8h, D0h), and Buffered Enhanced Factory Programming (80h, D0h). The following sections describe device programming in detail. Successful programming requires the addressed block to be unlocked. If the block is locked down, WP# must be deasserted and the block must be unlocked before attempting to program the block. Attempting to program a locked block causes a program error (SR[4,1] set) and termination of the operation. See Section 10.0, "Security" on page 31 for details on locking and unlocking blocks. 8.1 Word Programming Word programming operations are initiated by writing the Word Program Setup command to the device. This is followed by a second write to the device with the address and data to be programmed. The device outputs Status Register data when read. See Figure 30, "Word Program Flowchart" on page 73. VPP must be above VPPLK, and within the specified VPPL min/max values. During programming, the WSM executes a sequence of internally-timed events that program the desired data bits at the addressed location, and verifies that the bits are sufficiently programmed. Programming the flash memory array changes "ones" to "zeros". Memory array bits that are zeros can be changed to ones only by erasing the block. The Status Register can be examined for programming progress and errors by reading at any address. The device remains in the Read Status Register state until another command is written to the device. Status Register bit SR.7 indicates the programming status while the sequence executes. Commands that can be issued to the device during programming are Read Status Register, Read Device Identifier, Read CFI, and Read Array (this returns unknown data). When programming has finished, Status Register bit SR.4 (when set) indicates a programming failure. If SR.3 is set, the WSM could not perform the word programming operation because VPP was outside of its acceptable limits. If SR.1 is set, the word programming operation attempted to program a locked block, causing the operation to abort. Before issuing a new command, the Status Register contents should be examined and then cleared using the Clear Status Register command. Any valid command can follow, when word programming has completed. 8.2 Buffered Programming The device features a 512-word buffer to enable optimum programming performance. For Buffered Programming, data is first written to an on-chip write buffer. Then the buffer data is programmed into the flash memory array in buffer-size increments. This can improve system programming performance significantly over non-buffered programming. (see Figure 32, "Buffer Program Flowchart" on page 75). When the Buffered Programming Setup command is issued, Status Register information is updated and reflects the availability of the buffer. SR.7 indicates buffer availability: if set, the buffer is available; if cleared, the buffer is not available. Note: Datasheet 24 The device default state is to output SR data after the Buffer Programming Setup Command. CE# and OE# low drive device to update Status Register. It is not allowed Feb 2010 Order Number: 208043-04 P33-65nm to issue 70h to read SR data after E8h command otherwise 70h would be counted as Word Count. On the next write, a word count is written to the device at the buffer address. This tells the device how many data words will be written to the buffer, up to the maximum size of the buffer. On the next write, a device start address is given along with the first data to be written to the flash memory array. Subsequent writes provide additional device addresses and data. All data addresses must lie within the start address plus the word count. Optimum programming performance and lower power usage are obtained by aligning the starting address at the beginning of a 512-word boundary (A[9:1] = 0x000). The maximum buffer size would be 256-word if the misaligned address range is crossing a 512-word boundary during programming. After the last data is written to the buffer, the Buffered Programming Confirm command must be issued to the original block address. The WSM begins to program buffer contents to the flash memory array. If a command other than the Buffered Programming Confirm command is written to the device, a command sequence error occurs and SR[7,5,4] are set. If an error occurs while writing to the array, the device stops programming, and SR[7,4] are set, indicating a programming failure. When Buffered Programming has completed, additional buffer writes can be initiated by issuing another Buffered Programming Setup command and repeating the buffered program sequence. Buffered programming may be performed with VPP = VPPL or VPPH (see Section 13.2, "Operating Conditions" on page 47 for limitations when operating the device with VPP = VPPH). If an attempt is made to program past an erase-block boundary using the Buffered Program command, the device aborts the operation. This generates a command sequence error, and SR[5,4] are set. If Buffered programming is attempted while VPP is at or below VPPLK, SR[4,3] are set. If any errors are detected that have set Status Register bits, the Status Register should be cleared using the Clear Status Register command. 8.3 Buffered Enhanced Factory Programming Buffered Enhanced Factory Programing (BEFP) speeds up Multi-Level Cell (MLC) flash programming. The enhanced programming algorithm used in BEFP eliminates traditional programming elements that drive up overhead in device programmer systems. BEFP consists of three phases: Setup, Program/Verify, and Exit (see Figure 33, "BEFP Flowchart" on page 76). It uses a write buffer to spread MLC program performance across 512 data words. Verification occurs in the same phase as programming to accurately program the flash memory cell to the correct bit state. A single two-cycle command sequence programs the entire block of data. This enhancement eliminates three write cycles per buffer: two commands and the word count for each set of 512 data words. Host programmer bus cycles fill the device's write buffer followed by a status check. SR.0 indicates when data from the buffer has been programmed into sequential flash memory array locations. Following the buffer-to-flash array programming sequence, the Write State Machine (WSM) increments internal addressing to automatically select the next 512-word array boundary. This aspect of BEFP saves host programming equipment the address-bus setup overhead. Datasheet 25 Feb 2010 Order Number:208043-04 P33-65nm With adequate continuity testing, programming equipment can rely on the WSM's internal verification to ensure that the device has programmed properly. This eliminates the external post-program verification and its associated overhead. 8.3.1 BEFP Requirements and Considerations Table 10: BEFP Requirements Parameter/Issue Requirement Case Temperature TC = 30C 10C VCC Nominal Vcc Notes VPP Driven to VPPH Setup and Confirm Target block must be unlocked before issuing the BEFP Setup and Confirm commands. Programming The first-word address (WA0) of the block to be programmed must be held constant from the setup phase through all data streaming into the target block, until transition to the exit phase is desired. Buffer Alignment WA0 must align with the start of an array buffer boundary. Note: 1 Word buffer boundaries in the array are determined by A[9:1] (0x000 through 0x1FF). The alignment start point is A[9:1] = 0x000. Table 11: BEFP Considerations Parameter/Issue Requirement Notes Cycling For optimum performance, cycling must be limited below 50 erase cycles per block. 1 Programming blocks BEFP programs one block at a time; all buffer data must fall within a single block. 2 Suspend BEFP cannot be suspended. Programming the flash memory array Programming to the flash memory array can occur only when the buffer is full. 3 Notes: 1. Some degradation in performance may occur is this limit is exceeded, but the internal algorithm continues to work properly. 2. If the internal address counter increments beyond the block's maximum address, addressing wraps around to the beginning of the block. 3. If the number of words is less than 512, remaining locations must be filled with 0xFFFF. 8.3.2 BEFP Setup Phase After receiving the BEFP Setup and Confirm command sequence, Status Register bit SR.7 (Ready) is cleared, indicating that the WSM is busy with BEFP algorithm startup. A delay before checking SR.7 is required to allow the WSM enough time to perform all of its setups and checks (Block-Lock status, VPP level, etc.). If an error is detected, SR.4 is set and BEFP operation terminates. If the block was found to be locked, SR.1 is also set. SR.3 is set if the error occurred due to an incorrect VPP level. Note: Datasheet 26 Reading from the device after the BEFP Setup and Confirm command sequence outputs Status Register data. Do not issue the Read Status Register command; it will be interpreted as data to be loaded into the buffer. Feb 2010 Order Number: 208043-04 P33-65nm 8.3.3 BEFP Program/Verify Phase After the BEFP Setup Phase has completed, the host programming system must check SR[7,0] to determine the availability of the write buffer for data streaming. SR.7 cleared indicates the device is busy and the BEFP program/verify phase is activated. SR.0 indicates the write buffer is available. Two basic sequences repeat in this phase: loading of the write buffer, followed by buffer data programming to the array. For BEFP, the count value for buffer loading is always the maximum buffer size of 512 words. During the buffer-loading sequence, data is stored to sequential buffer locations starting at address 0x00. Programming of the buffer contents to the flash memory array starts as soon as the buffer is full. If the number of words is less than 512, the remaining buffer locations must be filled with 0xFFFF. Caution: The buffer must be completely filled for programming to occur. Supplying an address outside of the current block's range during a buffer-fill sequence causes the algorithm to exit immediately. Any data previously loaded into the buffer during the fill cycle is not programmed into the array. The starting address for data entry must be buffer size aligned, if not the BEFP algorithm will be aborted and the program fails and (SR.4) flag will be set. Data words from the write buffer are directed to sequential memory locations in the flash memory array; programming continues from where the previous buffer sequence ended. The host programming system must poll SR.0 to determine when the buffer program sequence completes. SR.0 cleared indicates that all buffer data has been transferred to the flash array; SR.0 set indicates that the buffer is not available yet for the next fill cycle. The host system may check full status for errors at any time, but it is only necessary on a block basis after BEFP exit. After the buffer fill cycle, no write cycles should be issued to the device until SR.0 = 0 and the device is ready for the next buffer fill. Note: Any spurious writes are ignored after a buffer fill operation and when internal program is proceeding. The host programming system continues the BEFP algorithm by providing the next group of data words to be written to the buffer. Alternatively, it can terminate this phase by changing the block address to one outside of the current block's range. The Program/Verify phase concludes when the programmer writes to a different block address; data supplied must be 0xFFFF. Upon Program/Verify phase completion, the device enters the BEFP Exit phase. 8.3.4 BEFP Exit Phase When SR.7 is set, the device has returned to normal operating conditions. A full status check should be performed at this time to ensure the entire block programmed successfully. When exiting the BEFP algorithm with a block address change, the read mode will not change. After BEFP exit, any valid command can be issued to the device. 8.4 Program Suspend Issuing the Program Suspend command while programming suspends the programming operation. This allows data to be accessed from the device other than the one being programmed. The Program Suspend command can be issued to any device address. A program operation can be suspended to perform reads only. Additionally, a Datasheet 27 Feb 2010 Order Number:208043-04 P33-65nm program operation that is running during an erase suspend can be suspended to perform a read operation (see Figure 31, "Program Suspend/Resume Flowchart" on page 74). When a programming operation is executing, issuing the Program Suspend command requests the WSM to suspend the programming algorithm at predetermined points. The device continues to output Status Register data after the Program Suspend command is issued. Programming is suspended when Status Register bits SR[7,2] are set. Suspend latency is specified in Section 15.5, "Program and Erase Characteristics" on page 60. To read data from the device, the Read Array command must be issued. Read Array, Read Status Register, Read Device Identifier, Read CFI, and Program Resume are valid commands during a program suspend. During a program suspend, deasserting CE# places the device in standby, reducing active current. VPP must remain at its programming level, and WP# must remain unchanged while in program suspend. If RST# is asserted, the device is reset. 8.5 Program Resume The Resume command instructs the device to continue programming, and automatically clears Status Register bits SR[7,2]. This command can be written to any address. If error bits are set, the Status Register should be cleared before issuing the next instruction. RST# must remain deasserted (see Figure 31, "Program Suspend/ Resume Flowchart" on page 74). 8.6 Program Protection When VPP = VIL, absolute hardware write protection is provided for all device blocks. If VPP is at or below VPPLK, programming operations halt and SR.3 is set indicating a VPPlevel error. Block lock registers are not affected by the voltage level on VPP; they may still be programmed and read, even if VPP is less than VPPLK. Figure 8: Example VPP Supply Connections VCC VPP VCC VPP VPP=VPPH VCC VPP * Low Voltage and Factory Programming Datasheet 28 PROT # VCC VPP 10K * Factory Programming with VPP = VPPH * Complete write/Erase Protection when VPP VPPLK VCC VCC * Low-voltage Programming only * Logic Control of Device Protection VCC VCC VPP * Low Voltage Programming Only * Full Device Protection Unavailable Feb 2010 Order Number: 208043-04 P33-65nm 9.0 Erase Operation Flash erasing is performed on a block basis. An entire block is erased each time an erase command sequence is issued, and only one block is erased at a time. When a block is erased, all bits within that block read as logical ones. The following sections describe block erase operations in detail. 9.1 Block Erase Block erase operations are initiated by writing the Block Erase Setup command to the address of the block to be erased (see Section 6.2, "Device Command Bus Cycles" on page 20). Next, the Block Erase Confirm command is written to the address of the block to be erased. If the device is placed in standby (CE# deasserted) during an erase operation, the device completes the erase operation before entering standby. VPP must be above VPPLK and the block must be unlocked (see Figure 34, "Block Erase Flowchart" on page 77). During a block erase, the WSM executes a sequence of internally-timed events that conditions, erases, and verifies all bits within the block. Erasing the flash memory array changes "zeros" to "ones". Memory array block that are ones can be changed to zeros only by programming the block. The Status Register can be examined for block erase progress and errors by reading any address. The device remains in the Read Status Register state until another command is written. SR.0 indicates whether the addressed block is erasing. Status Register bit SR.7 is set upon erase completion. Status Register bit SR.7 indicates block erase status while the sequence executes. When the erase operation has finished, Status Register bit SR.5 indicates an erase failure if set. SR.3 set would indicate that the WSM could not perform the erase operation because VPP was outside of its acceptable limits. SR.1 set indicates that the erase operation attempted to erase a locked block, causing the operation to abort. Before issuing a new command, the Status Register contents should be examined and then cleared using the Clear Status Register command. Any valid command can follow once the block erase operation has completed. 9.2 Blank Check The Blank Check operation determines whether a specified main block is blank (i.e. completely erased). Without Blank Check, Block Erase would be the only other way to ensure a block is completely erased. Blank Check is especially useful in the case of erase operation interrupted by power loss event. Blank check can apply to only one block at a time, and no operations other than Status Register Reads are allowed during Blank Check (e.g. reading array data, program, erase etc). Suspend and resume operations are not supported during Blank Check, nor is Blank Check supported during any suspended operations. Blank Check operations are initiated by writing the Blank Check Setup command to the block address. Next, the Check Confirm command is issued along with the same block address. When a successful command sequence is entered, the device automatically enters the Read Status State. The WSM then reads the entire specified block, and determines whether any bit in the block is programmed or over-erased. The status register can be examined for Blank Check progress and errors by reading any address within the block being accessed. During a blank check operation, the Status Register indicates a busy status (SR.7 = 0). Upon completion, the Status Datasheet 29 Feb 2010 Order Number:208043-04 P33-65nm Register indicates a ready status (SR.7 = 1). The Status Register should be checked for any errors, and then cleared. If the Blank Check operation fails, which means the block is not completely erased, the Status Register bit SR.5 will be set ("1"). CE# or OE# toggle (during polling) updates the Status Register. After examining the Status Register, it should be cleared by the Clear Status Register command before issuing a new command. The device remains in Status Register Mode until another command is written to the device. Any command can follow once the Blank Check command is complete. 9.3 Erase Suspend Issuing the Erase Suspend command while erasing suspends the block erase operation. This allows data to be accessed from memory locations other than the one being erased. The Erase Suspend command can be issued to any device address. A block erase operation can be suspended to perform a word or buffer program operation, or a read operation within any block except the block that is erase suspended (see Figure 36, "Erase Suspend/Resume Flowchart" on page 79). When a block erase operation is executing, issuing the Erase Suspend command requests the WSM to suspend the erase algorithm at predetermined points. The device continues to output Status Register data after the Erase Suspend command is issued. Block erase is suspended when Status Register bits SR[7,6] are set. Suspend latency is specified in Section 15.5, "Program and Erase Characteristics" on page 60. To read data from the device (other than an erase-suspended block), the Read Array command must be issued. During Erase Suspend, a Program command can be issued to any block other than the erase-suspended block. Block erase cannot resume until program operations initiated during erase suspend complete. Read Array, Read Status Register, Read Device Identifier, Read CFI, and Erase Resume are valid commands during Erase Suspend. Additionally, Clear Status Register, Program, Program Suspend, Block Lock, Block Unlock, and Block Lock-Down are valid commands during Erase Suspend. During an erase suspend, deasserting CE# places the device in standby, reducing active current. VPP must remain at a valid level, and WP# must remain unchanged while in erase suspend. If RST# is asserted, the device is reset. 9.4 Erase Resume The Erase Resume command instructs the device to continue erasing, and automatically clears SR[7,6]. This command can be written to any address. If status register error bits are set, the Status Register should be cleared before issuing the next instruction. RST# must remain deasserted. 9.5 Erase Protection When VPP = VIL, absolute hardware erase protection is provided for all device blocks. If VPP is at or below VPPLK, erase operations halt and SR.3 is set indicating a VPP-level error. Datasheet 30 Feb 2010 Order Number: 208043-04 P33-65nm 10.0 Security The device features security modes used to protect the information stored in the flash memory array. The following sections describe each security mode in detail. 10.1 Block Locking Individual instant block locking is used to protect user code and/or data within the flash memory array. All blocks power up in a locked state to protect array data from being altered during power transitions. Any block can be locked or unlocked with no latency. Locked blocks cannot be programmed or erased; they can only be read. Software-controlled security is implemented using the Block Lock and Block Unlock commands. Hardware-controlled security can be implemented using the Block LockDown command along with asserting WP#. Also, VPP data security can be used to inhibit program and erase operations (see Section 8.6, "Program Protection" on page 28 and Section 9.5, "Erase Protection" on page 30). 10.1.1 Lock Block To lock a block, issue the Block Lock Setup command. The next command must be the Block Lock command issued to the desired block's address (see Section 6.2, "Device Command Bus Cycles" on page 20 and Figure 35, "Block Lock Operations Flowchart" on page 78). If the Configure Read Configuration Register command is issued after the Block Lock Setup command, the device configures the RCR instead. Block lock and unlock operations are not affected by the voltage level on VPP. The block lock bits may be modified and/or read even if VPP is at or below VPPLK. 10.1.2 Unlock Block The Block Unlock command is used to unlock blocks (see Section 6.2, "Device Command Bus Cycles" on page 20). Unlocked blocks can be read, programmed, and erased. Unlocked blocks return to a locked state when the device is reset or powered down. If a block is in a lock-down state, WP# must be deasserted before it can be unlocked (see Figure 9, "Block Locking State Diagram" on page 32). 10.1.3 Lock-Down Block A locked or unlocked block can be locked-down by writing the Block Lock-Down command sequence (see Section 6.2, "Device Command Bus Cycles" on page 20). Blocks in a lock-down state cannot be programmed or erased; they can only be read. However, unlike locked blocks, their locked state cannot be changed by software commands alone. A locked-down block can only be unlocked by issuing the Block Unlock command with WP# deasserted. To return an unlocked block to locked-down state, a Block Lock-Down command must be issued prior to changing WP# to VIL. Locked-down blocks revert to the locked state upon reset or power up the device (see Figure 9, "Block Locking State Diagram" on page 32). 10.1.4 Block Lock Status The Read Device Identifier command is used to determine a block's lock status (see Section 7.2, "Read Device Identifier" on page 22). Data bits DQ[1:0] display the addressed block's lock status; DQ0 is the addressed block's lock bit, while DQ1 is the addressed block's lock-down bit.

To change block locking during an erase operation, first issue the Erase Suspend command. Monitor the Status Register until SR[7,6] are set, indicating the device is suspended and ready to accept another command. Next, write the desired lock command sequence to a block, which changes the lock state of that block. After completing block lock or unlock operations, resume the erase operation using the Erase Resume command. Note: A Lock Block Setup command followed by any command other than Lock Block, Unlock Block, or Lock-Down Block produces a command sequence error and set Status Register bits SR[4,5]. If a command sequence error occurs during an erase suspend, SR[4,5] remains set, even after the erase operation is resumed. Unless the Status Register is cleared using the Clear Status Register command before resuming the erase operation, possible erase errors may be masked by the command sequence error. If a block is locked or locked-down during an erase suspend of the same block, the lock status bits change immediately. However, the erase operation completes when it is resumed. Block lock operations cannot occur during a program suspend. See Appendix A, "Write State Machine" on page 82, which shows valid commands during an erase suspend. Datasheet 32 Feb 2010 Order Number: 208043-04 P33-65nm 10.2 Selectable OTP Blocks P33-65nm provides the backward compatible One Time Programming permanent block lock security feature. Blocks from the main array can be optionally configured as OTP. Ask your local Numonyx Sales representative for details about these selectable OTP implementations. 10.3 Password Access The Password Access is a security enhancement offered on P33-65nm device. This feature protects information stored in array blocks by preventing content alteration or reads until a valid 64-bit password is received. The Password Access may be combined with Flexible block blocking to create a multi-tiered solution. Please contact your Numonyx Sales for further details concerning the Password Access. Datasheet 33 Feb 2010 Order Number:208043-04 P33-65nm 11.0 Register When non-array reads are performed in asynchronous page mode only the first data is valid and all subsequent data are undefined. When a non-array read operation occurs as synchronous burst mode, the same word of data requested will be output on successive clock edges until the burst length requirements are satisfied. 11.1 Status Register (SR) The Status Register provides the ready/busy information of the device, as well as the error information about the program, erase, VPP and block-locked operations. Please refer to Section 7.4, "Read Status Register" on page 23. Please refer to Section 7.5, "Clear Status Register" on page 23.

Program error - operation aborted. Erase error - operation aborted. Command sequence error - command aborted. 4 Program Status (PS) 3 VPP Status (VPPS) 0 = VPP within acceptable limits during program or erase operation. 1 = VPP VPPLK during program or erase operation. 2 Program Suspend Status (PSS) 0 = Program suspend not in effect. 1 = Program suspend in effect. 1 Block-Locked Status (BLS) 0 = Block not locked during program or erase. 1 = Block locked during program or erase; operation aborted. 0 BEFP Write Status (BWS) After Buffered Enhanced Factory Programming (BEFP) data is loaded into the buffer: 0 = BEFP complete. 1 = BEFP in-progress. Notes: 1. Always clear the Status Register prior to resuming erase operations. It avoids Status Register ambiguity when issuing commands during Erase Suspend. If a command sequence error occurs during an erase-suspend state, the Status Register contains the command sequence error status (SR[7,5,4] set). When the erase operation resumes and finishes, possible errors during the erase operation cannot be detected via the Status Register because it contains the previous error status 2. BEFP mode is only valid in array blocks. Datasheet 34 Feb 2010 Order Number: 208043-04 P33-65nm 11.2 Read Configuration Register (RCR) The RCR is a 16-bit read/write register used to select the read mode (synchronous or asynchronous), and to configure synchronous burst characteristics of the device. To modify RCR settings, use the Configure Read Configuration Register command (see Section 6.2, "Device Command Bus Cycles" on page 20). RCR contents can be examined using the Read Device Identifier command, and then reading from offset 0x05 (see Section 7.2, "Read Device Identifier" on page 22). Upon power-up or exit from reset, the RCR defaults to asynchronous mode. The RCR is shown in Table 13. The following sections describe each RCR bit function.

When the RM bit is set, asynchronous page mode is selected (default). When RM is cleared, synchronous burst mode is selected. 11.2.2 Latency Count (RCR[14:11]) The Latency Count (LC) bits tell the device how many clock cycles must elapse from the rising edge of ADV# (or from the first valid clock edge after ADV# is asserted) until the first valid data word is driven onto DQ[15:0]. The input clock frequency is used to determine this value and Figure 10 shows the data output latency for the different settings of LC. The maximum Latency Count for P33 would be Code 4 based on the Max clock frequency specification of 52 MHz, and there will be zero WAIT States when bursting within the word line. Please also refer to Section 11.2.3, "End of Word Line (EOWL) Considerations" on page 38 for more information on EOWL. Refer to Table 14, "LC and Frequency Support" on page 37 for Latency Code Settings.

That is, A[4:1] of start address does not equal 0x0. Figure 12, "End of Wordline Timing Diagram" on page 38 illustrates the end of wordline WAIT state(s), which occur after the first 16-word boundary is reached. The number of data words and the number of WAIT states is summarized in Table 15, "End of Wordline Data and WAIT state Comparison" on page 39 for both P33-130nm and P33-65nm devices.

When WP is set, WAIT is asserted high. When WP is cleared, WAIT is asserted low (default). WAIT changes state on valid clock edges during active bus cycles (CE# asserted, OE# asserted, RST# deasserted). Table 16: WAIT Functionality Table Condition WAIT Notes CE# = `1', OE# = `X' or CE# = `0', OE# = `1' High-Z 1 CE# ='0', OE# = `0' Active 1 Synchronous Array Reads Active 1 Synchronous Non-Array Reads Active 1 All Asynchronous Reads Deasserted All Writes High-Z 1 1,2 Notes: 1. Active: WAIT is asserted until data becomes valid, then deasserts. 2. When OE# = VIH during writes, WAIT = High-Z. 11.2.5 WAIT Delay (RCR.8) The WAIT Delay (WD) bit controls the WAIT assertion-delay behavior during synchronous burst reads. WAIT can be asserted either during or one data cycle before valid data is output on DQ[15:0]. When WD is set, WAIT is deasserted one data cycle before valid data (default). When WD is cleared, WAIT is deasserted during valid data. 11.2.6 Burst Sequence (RCR.7) The Burst Sequence (BS) bit selects linear-burst sequence (default). Only linear-burst sequence is supported.

This clock edge is used at the start of a burst cycle, to output synchronous data, and to assert/deassert WAIT. 11.2.8 Burst Wrap (RCR.3) The Burst Wrap (BW) bit determines whether 4, 8, or 16-word burst length accesses wrap within the selected word-length boundaries or cross word-length boundaries. When BW is set, burst wrapping does not occur (default). When BW is cleared, burst wrapping occurs. Datasheet 40 Feb 2010 Order Number: 208043-04 P33-65nm 11.2.9 Burst Length (RCR[2:0]) The Burst Length bits (BL[2:0]) select the linear burst length for all synchronous burst reads of the flash memory array. The burst lengths are 4-word, 8-word, 16-word or continuous word. Continuous burst accesses are linear only, and do not wrap within any word length boundaries (see Table 17, "Burst Sequence Word Ordering" on page 40). When a burst cycle begins, the device outputs synchronous burst data until it reaches the end of the "burstable" address space. 11.3 One-Time Programmable (OTP) Registers The device contains 17 one-time programmable (OTP) registers that can be used to implement system security measures and/or device identification. Each OTP register can be individually locked. The first 128-bit OTP Register is comprised of two 64-bit (8-word) segments. The lower 64-bit segment is pre-programmed at the Numonyx factory with a unique 64-bit number. The upper 64-bit segment, as well as the other sixteen 128-bit OTP Registers, are blank. Users can program these registers as needed. Once programmed, users can then lock the OTP Register(s) to prevent additional bit programming (see Figure 13, "OTP Register Map" on page 42). Each OTP Register has an associated Lock Register bit. When a Lock Register bit is programmed, the associated OTP Register can only be read; it can no longer be programmed. Each OTP Register can be accessed multiple times to program individual bits, as long as the register remains unlocked. Additionally, because the Lock Register bits themselves are OTP, when programmed, Lock Register bits cannot be erased. Therefore, when a OTP Register is locked, it cannot be unlocked.

To read the OTP Register, first issue the Read Device Identifier command at OTP-RA address to place the device in the Read Device Identifier state (see Section 6.2, "Device Command Bus Cycles" on page 20). Next, perform a read operation using the address offset corresponding to the register to be read. Table 8, "Device Identifier Information" on page 22 shows the address offsets of the OTP Registers and Lock Registers. OTP register and Lock Register data is read 16 bits at a time. 11.3.2 Programming the OTP Registers To program an OTP Registers, first issue the Program OTP Register command at the device base address plus the offset of the desired OTP Register location (See Figure 13, "OTP Register Map" on page 42). Next, write the desired OTP Register data to the same OTP Register address. See Section 6.2, "Device Command Bus Cycles" on page 20. Datasheet 42 Feb 2010 Order Number: 208043-04 P33-65nm The device programs the 64-bit and Sixteen 128-bit user-programmable Protection Registers data 16 bits at a time (see Figure 37, "OTP Register Programming Flowchart" on page 80). Issuing the Program OTP Register command outside of the OTP Register's address space causes a program error (SR.4 set). Attempting to program a locked OTP Register causes a program error (SR.4 set) and a lock error (SR.1 set). Note: When programming the OTP bits in the OTP registers for a Top Parameter Device, the upper address A[Max:17] must also be driven high (VIH) for TSOP and Easy BGA packages. 11.3.3 Locking the OTP Registers Each OTP Register can be locked by programming its respective lock bit in the Lock Register. To lock a OTP Register, program the corresponding bit in the Lock Register by issuing the Program Lock Register command, followed by the desired Lock Register data (see Section 6.2, "Device Command Bus Cycles" on page 20). The physical addresses of the Lock Registers are 0x80 for register 0 and 0x89 for register 1. These addresses are used when programming the lock registers (see Table 8, "Device Identifier Information" on page 22). Bit 0 of Lock Register 0 is already programmed during the manufacturing process at Numonyx factory, locking the lower half segment of the first 128-bit OTP Register. Bit 1 of Lock Register 0 can be programmed by the user to lock the upper half of the first 128-bit OTP Register. When programming Bit 1 of Lock Register 0, all other bits need to be left as `1' such that the data programmed is 0xFFFD. Lock Register 1 controls the locking of the upper sixteen 128-bit OTP Registers. Each bit of Lock Register 1 corresponds to a specific 128-bit OTP Registers; e.g., programming a bit in LR1.0 locks the corresponding OTP Register 1. Caution: Datasheet 43 After being locked, the OTP Registers cannot be unlocked.

Otherwise VCC and VCCQ should attain their minimum operating voltage before applying VPP. Power supply transitions should only occur when RST# is low. This protects the device from accidental programming or erasure during power transitions. 12.2 Reset Specifications Asserting RST# during a system reset is important with automated program/erase devices because systems typically expect to read from flash memory when coming out of reset. If a CPU reset occurs without a flash memory reset, proper CPU initialization may not occur. This is because the flash memory may be providing status information, instead of array data as expected. Connect RST# to the same active low reset signal used for CPU initialization. Also, because the device is disabled when RST# is asserted, it ignores its control inputs during power-up/down. Invalid bus conditions are masked, providing a level of memory protection. Table 18: Power and Reset Num Symbol P1 tPLPH P2 tPLRH P3 tVCCPH Notes: 1. 2. 3. 4. 5. 6. 7. Parameter RST# pulse width low Min Max Unit Notes 100 - ns 1,2,3,4 s 1,3,4,7 RST# low to device reset during erase - 25 RST# low to device reset during program - 25 300 - VCC Power valid to RST# de-assertion (high) 1,3,4,7 1,4,5,6 These specifications are valid for all device versions (packages and speeds). The device may reset if tPLPH is < tPLPH Min, but this is not guaranteed. Not applicable if RST# is tied to VCC. Sampled, but not 100% tested. When RST# is tied to the VCC supply, device will not be ready until tVCCPH after VCC VCCMIN. When RST# is tied to the VCCQ supply, device will not be ready until tVCCPH after VCC VCCMIN. Reset completes within tPLPH if RST# is asserted while no erase or program operation is executing.

Three basic power supply current considerations are: 1) standby current levels; 2) active current levels; and 3) transient peaks produced when CE# and OE# are asserted and deasserted. When the device is accessed, many internal conditions change. Circuits within the device enable charge-pumps, and internal logic states change at high speed. All of these internal activities produce transient signals. Transient current magnitudes depend on the device outputs' capacitive and inductive loading. Two-line control and correct de-coupling capacitor selection suppress transient voltage peaks. Because flash memory devices draw their power from VCC, VPP, and VCCQ, each power connection should have a 0.1 F ceramic capacitor to ground. High-frequency, inherently low-inductance capacitors should be placed as close as possible to package leads. Additionally, for every eight devices used in the system, a 4.7 F electrolytic capacitor should be placed between power and ground close to the devices. The bulk capacitor is meant to overcome voltage droop caused by PCB trace inductance.

A write operation can be terminated with either CE# or WE#. Sampled, not 100% tested. Write pulse width low (tWLWH or tELEH) is defined from CE# or WE# low (whichever occurs last) to CE# or WE# high (whichever occurs first). Hence, tWLWH = tELEH = tWLEH = tELWH. Write pulse width high (tWHWL or tEHEL) is defined from CE# or WE# high (whichever occurs first) to CE# or WE# low (whichever occurs last). Hence, tWHWL = tEHEL = tWHEL = tEHWL). tWHVH or tWHCH/L must be met when transiting from a write cycle to a synchronous burst read. VPP and WP# should be at a valid level until erase or program success is determined. This specification is only applicable when transiting from a write cycle to an asynchronous read. See spec W19 and W20 for synchronous read. When doing a Read Status operation following any command that alters the Status Register, W14 is 20ns. Add 10ns if the write operations results in a RCR or block lock status change, for the subsequent read operation to reflect this change. These specs are required only when the device is in a synchronous mode and clock is active during address setup phase.

Datasheet 61 Feb 2010 Order Number:208043-04 P33-65nm Appendix A Supplemental Reference Information A.1 Common Flash Interface The Common Flash Interface (CFI) is part of an overall specification for multiple command-set and control-interface descriptions. This appendix describes the database structure containing the data returned by a read operation after issuing the Read CFI command (see Section 6.2, "Device Command Bus Cycles" on page 20). System software can parse this database structure to obtain information about the flash device, such as block size, density, bus width, and electrical specifications. The system software will then know which command set(s) to use to properly perform flash writes, block erases, reads and otherwise control the flash device. A.1.1 Query Structure Output The Query database allows system software to obtain information for controlling the flash device. This section describes the device's CFI-compliant interface that allows access to Query data. Query data are presented on the lowest-order data outputs (DQ7-0) only. The numerical offset value is the address relative to the maximum bus width supported by the device. On this family of devices, the Query table device starting address is a 10h, which is a word address for x16 devices. For a word-wide (x16) device, the first two Query-structure bytes, ASCII "Q" and "R," appear on the low byte at word addresses 10h and 11h. This CFI-compliant device outputs 00h data on upper bytes. The device outputs ASCII "Q" in the low byte (DQ7-0) and 00h in the high byte (DQ15-8). At Query addresses containing two or more bytes of information, the least significant data byte is presented at the lower address, and the most significant data byte is presented at the higher address. In all of the following tables, addresses and data are represented in hexadecimal notation, so the "h" suffix has been dropped. In addition, since the upper byte of wordwide devices is always "00h," the leading "00" has been dropped from the table notation and only the lower byte value is shown. Any x16 device outputs have 00h on the upper byte in this mode.

"Illegal commands" include commands outside of the allowed command set. The device defaults to "Read Array" on powerup. If a "Read Array" is attempted when the device is busy, the result will be "garbage" data (we should not tell the user that it will actually be Status Register data). The key point is that the output mux will be pointing to the "array", but garbage data will be output. "Read ID" and "Read Query" commands do the exact same thing in the device. The ID and Query data are located at different locations in the address map. The Clear Status command only clears the error bits in the status register if the device is not in the following modes:1. WSM running (Pgm Busy, Erase Busy, Pgm Busy In Erase Suspend, OTP Busy, BEFP modes) 2. Suspend states (Erase Suspend, Pgm Suspend, Pgm Suspend In Erase Suspend). BEFP writes are only allowed when the status register bit #0 = 0 or else the data is ignored. Confirm commands (Lock Block, Unlock Block, Lock-Down Block, Configuration Register and Blank Check) perform the operation and then move to the Ready State. Buffered programming will botch when a different block address (as compared to the address given on the first data write cycle) is written during the BP Load1 and BP Load2 states. All two cycle commands will be considered as a contiguous whole during device suspend states. Individual commands will not be parsed separately. (I.e. If an erase set-up command is issued followed by a D0h command, the D0h command will not resume the program operation. Issuing the erase set-up places the CUI in an "illegal state". A subsequent command will clear the "illegal state", but the command will be otherwise ignored.
