Pin Descriptions Symbol Type A0-A21 INPUT Name and Function ADDRESS INPUTS: Inputs for addresses. 64M: A0-A21 DQ0-DQ15 INPUT/ OUTPUT DATA INPUTS/OUTPUTS: Inputs data and commands during CUI (Command User Interface) write cycles, outputs data during memory array, status register, query code, identifier code and partition configuration register code reads. Data pins float to highimpedance (High Z) when the chip or outputs are deselected. Data is internally latched during an erase or program cycle. CE# INPUT CHIP ENABLE: Activates the device's control logic, input buffers, decoders and sense amplifiers. CE#-high (VIH) deselects the device and reduces power consumption to standby levels. RST# INPUT RESET: When low (VIL), RST# resets internal automation and inhibits write operations which provides data protection. RST#-high (VIH) enables normal operation. After power-up or reset mode, the device is automatically set to read array mode. RST# must be low during power-up/down. OE# INPUT OUTPUT ENABLE: Gates the device's outputs during a read cycle. WE# INPUT WRITE ENABLE: Controls writes to the CUI and array blocks. Addresses and data are latched on the rising edge of CE# or WE# (whichever goes high first). WP# INPUT WRITE PROTECT: When WP# is VIL, locked-down blocks cannot be unlocked. Erase or program operation can be executed to the blocks which are not locked and not lockeddown. When WP# is VIH, lock-down is disabled. VPP MONITORING POWER SUPPLY VOLTAGE: VPP is not used for power supply pin. With VPPVPPLK, block erase, full chip erase, (page buffer) program or OTP program cannot be executed and should not be attempted. Applying 9.5V0.5V to VPP provides fast erasing or fast programming mode. In this INPUT/SUPPLY mode, VPP is power supply pin. Applying 9.5V0.5V to VPP during erase/program can only be done for a maximum of 1,000 cycles on each block. VPP may be connected to 9.5V0.5V for a total of 80 hours maximum. Use of this pin at 9.5V beyond these limits may reduce block cycling capability or cause permanent damage. VCC SUPPLY DEVICE POWER SUPPLY (2.7V-3.6V): With VCCVLKO, all write attempts to the flash memory are inhibited. Device operations at invalid VCC voltage (see DC Characteristics) produce spurious results and should not be attempted. VCCQ SUPPLY INPUT/OUTPUT POWER SUPPLY (2.7V-3.6V): Power supply for all input/output pins. GND SUPPLY GROUND: Do not float any ground pins. Rev. 2.45 LHF64FG8 5 Table 2.

"X" denotes the operation available. 2. Configurative Partition Dual Work Restrictions: Status register reflects partition state, not WSM (Write State Machine) state - this allows a status register for each partition. Only one partition can be erased or programmed at a time - no command queuing. Commands must be written to an address within the block targeted by that command.

The Read Query command is available for reading CFI (Common Flash Interface) information. 5. Block erase, full chip erase or (page buffer) program cannot be executed when the selected block is locked. Unlocked block can be erased or programmed when RST# is VIH. 6. Either 40H or 10H are recognized by the CUI (Command User Interface) as the program setup. 7. Following the third bus cycle, input the program sequential address and write data of "N" times. Finally, input the any valid address within the target block to be programmed and the confirm command (D0H). Refer to Appendix of Rev. 2.45 LHF64FG8 11 LH28F640BF series for details. 8. If the program operation in one partition is suspended and the erase operation in other partition is also suspended, the suspended program operation should be resumed first, and then the suspended erase operation should be resumed next. 9. Full chip erase and OTP program operations can not be suspended. The OTP Program command can not be accepted while the block erase operation is being suspended. 10. Following the Clear Block Lock Bit command, block which is not locked-down is unlocked when WP# is VIL. When WP# is VIH, lock-down bit is disabled and the selected block is unlocked regardless of lock-down configuration. 11. Commands other than those shown above are reserved by SHARP for future device implementations and should not be used. Rev. 2.45 LHF64FG8 12 Table 8. Functions of Block Lock(5) and Block Lock-Down Current State State WP# DQ1 (1) DQ0(1) State Name Erase/Program Allowed (2) [000] 0 0 0 Unlocked Yes [001](3) 0 0 1 Locked No [011] 0 1 1 Locked-down No [100] 1 0 0 Unlocked Yes [101](3) 1 0 1 Locked No [110](4) 1 1 0 Lock-down Disable Yes [111] 1 1 1 Lock-down Disable No NOTES: 1. DQ0=1: a block is locked; DQ0=0: a block is unlocked. DQ1=1: a block is locked-down; DQ1=0: a block is not locked-down. 2. Erase and program are general terms, respectively, to express: block erase, full chip erase and (page buffer) program operations. 3. At power-up or device reset, all blocks default to locked state and are not locked-down, that is, [001] (WP#=0) or [101] (WP#=1), regardless of the states before power-off or reset operation. 4. When WP# is driven to VIL in [110] state, the state changes to [011] and the blocks are automatically locked. 5. OTP (One Time Program) block has the lock function which is different from those described above. Table 9.

"Set Lock" means Set Block Lock Bit command, "Clear Lock" means Clear Block Lock Bit command and "Set Lock-down" means Set Block Lock-Down Bit command. 2. When the Set Block Lock-Down Bit command is written to the unlocked block (DQ0=0), the corresponding block is locked-down and automatically locked at the same time. 3. "No Change" means that the state remains unchanged after the command written. 4. In this state transitions table, assumes that WP# is not changed and fixed VIL or VIH. Rev. 2.45 LHF64FG8 13 Table 10.

"WP#=01" means that WP# is driven to VIH and "WP#=10" means that WP# is driven to VIL. 2. State transition from the current state [011] to the next state depends on the previous state. 3. When WP# is driven to VIL in [110] state, the state changes to [011] and the blocks are automatically locked. 4. In this state transitions table, assumes that lock configuration commands are not written in previous, current and next state. Rev. 2.45 LHF64FG8 14 Table 11.

Even if the SR.7 is "1", the WSM may be occupied by the other partition when the device is set to 2, 3 or 4 partitions configuration. Check SR.7 to determine block erase, full chip erase, (page buffer) program or OTP program completion. SR.6 - SR.1 are invalid while SR.7="0". If both SR.5 and SR.4 are "1"s after a block erase, full chip erase, (page buffer) program, set/clear block lock bit, set block lock-down bit, set partition configuration register attempt, an improper command sequence was entered. SR.3 does not provide a continuous indication of VPP level. The WSM interrogates and indicates the VPP level only after Block Erase, Full Chip Erase, (Page Buffer) Program or OTP Program command sequences.

If read or (page buffer) program is executed while in block erase suspend mode, the device's current draw is the sum of ICCES and ICCR or ICCW. If read is executed while in (page buffer) program suspend mode, the device's current draw is the sum of ICCWS and ICCR. 3. Block erase, full chip erase, (page buffer) program and OTP program are inhibited when VPPVPPLK, and not guaranteed in the range between VPPLK(max.) and VPPH1(min.), between VPPH1(max.) and VPPH2(min.) and above VPPH2(max.). 4. The Automatic Power Savings (APS) feature automatically places the device in power save mode after read cycle completion. Standard address access timings (tAVQV) provide new data when addresses are changed. 5. Sampled, not 100% tested. 6. VPP is not used for power supply pin. With VPPVPPLK, block erase, full chip erase, (page buffer) program and OTP program cannot be executed and should not be attempted. Applying 9.5V0.5V to VPP provides fast erasing or fast programming mode. In this mode, VPP is power supply pin and supplies the memory cell current for block erasing and (page buffer) programming. Use similar power supply trace widths and layout considerations given to the VCC power bus. Applying 9.5V0.5V to VPP during erase/program can only be done for a maximum of 1,000 cycles on each block. VPP may be connected to 9.5V0.5V for a total of 80 hours maximum. 7. The operating current in dual work is the sum of the operating current (read, erase, program) in each plane. 8. For all pins other than those shown in test conditions, input level is VCCQ or GND.

Rev. 1.10 v A-3 STATUS REGISTER READ OPERATIONS If AC timing for reading the status register described in specifications is not satisfied, a system processor can check the status register bit SR.15 instead of SR.7 to determine when the erase or program operation has been completed. Table A-3-1. Status Register Definition (SR.15 and SR.7) NOTES: SR.15 = WRITE STATE MACHINE STATUS: (DQ15) 1 = Ready in All Partitions 0 = Busy in Any Partition SR.15 indicates the status of WSM (Write State Machine). If SR.15="0", erase or program operation is in progress in any partition. SR.7 = WRITE STATE MACHINE STATUS FOR EACH PARTITION: (DQ 7) 1 = Ready in the Addressed Partition 0 = Busy in the Addressed Partition SR.7 indicates the status of the partition. If SR.7="0", erase or program operation is in progress in the addressed partition. Even if the SR.7 is "1", the WSM may be occupied by the other partition.
