Featuring high performance Word-Program, the flash memory bank provides a maximum Word-Program time of 14 sec. The entire flash memory bank can be erased and programmed word-by-word in typically 2 seconds for the SST32HF202, 4 seconds for the SST32HF402, and 8 seconds for the SST32HF802, when using interface features such as Toggle Bit or Data# Polling to indicate the completion of Program operation. To protect against inadvertent flash write, the SST32HF202/402/802 devices contain onchip hardware and software data protection schemes. The SST32HF202/402/802 devices offer a guaranteed endurance of 10,000 cycles. Data retention is rated at greater than 100 years. The SST32HF202/402/802 devices consist of two independent memory banks with respective bank enable signals. The Flash and SRAM memory banks are superimposed in the same memory address space. Both (c)2008 Silicon Storage Technology, Inc. S71209-07-EOL 02/08 1 memory banks share common address lines, data lines, WE# and OE#. The memory bank selection is done by memory bank enable signals. The SRAM bank enable signal, BES# selects the SRAM bank. The flash memory bank enable signal, BEF# selects the flash memory bank. The WE# signal has to be used with Software Data Protection (SDP) command sequence when controlling the Erase and Program operations in the flash memory bank. The SDP command sequence protects the data stored in the flash memory bank from accidental alteration. The SST32HF202/402/802 provide the added functionality of being able to simultaneously read from or write to the SRAM bank while erasing or programming in the flash memory bank. The SRAM memory bank can be read or written while the flash memory bank performs SectorErase, Bank-Erase, or Word-Program concurrently. All flash memory Erase and Program operations will automatically latch the input address and data signals and complete the operation in background without further input stimulus requirement. Once the internally controlled Erase or Program cycle in the flash bank has commenced, the SRAM bank can be accessed for Read or Write.

For systems requiring low power and small form factor, the SST32HF202/402/802 devices significantly improve performance and reliability, while lowering power consumption, when compared with multiple chip solutions. The SST32HF202/402/802 inherently use less energy during erase and program than alternative flash technologies. The total energy consumed is a function of the applied voltage, current, and time of application. Since for any given voltage range, the SuperFlash technology uses less current to program and has a shorter erase time, the total energy consumed during any Erase or Program operation is less than alternative flash technologies. The SRAM Read operation of the SST32HF202/402/802 is controlled by OE# and BES#, both have to be low with WE# high for the system to obtain data from the outputs. BES# is used for SRAM bank selection. OE# is the output control and is used to gate data from the output pins. The data bus is in high impedance state when OE# is high. See Figure 3 for the Read cycle timing diagram. SRAM Write The SRAM Write operation of the SST32HF202/402/802 is controlled by WE# and BES#, both have to be low for the system to write to the SRAM. During the Word-Write operation, the addresses and data are referenced to the rising edge of either BES# or WE#, whichever occurs first. The write time is measured from the last falling edge to the first rising edge of BES# or WE#. See Figures 4 and 5 for the Write cycle timing diagrams. The SuperFlash technology provides fixed Erase and Program times, independent of the number of Erase/Program cycles that have occurred. Therefore the system software or hardware does not have to be modified or de-rated as is necessary with alternative flash technologies, whose Erase and Program times increase with accumulated Erase/Program cycles. Flash Operation With BEF# active, the SST32HF202 operates as 128K x16 flash memory, the SST32HF402 operates as 256K x16 flash memory, and the SST32HF802 operates as 512K x16 flash memory. The flash memory bank is read using the common address lines, data lines, WE# and OE#. Erase and Program operations are initiated with the JEDEC standard SDP command sequences. Address and data are latched during the SDP commands and during the internally-timed Erase and Program operations. Device Operation The ComboMemory uses BES# and BEF# to control operation of either the SRAM or the flash memory bank. When BES# is low, the SRAM Bank is activated for Read and Write operation. When BEF# is low the flash bank is activated for Read, Program or Erase operation. BES# and BEF# cannot be at low level at the same time. If BES# and BEF# are both asserted to low level bus contention will result and the device may suffer permanent damage. All address, data, and control lines are shared by SRAM Bank and flash bank which minimizes power consumption and loading. The device goes into standby when both bank enables are high. Flash Read The Read operation of the SST32HF202/402/802 devices is controlled by BEF# and OE#. Both have to be low, with WE# high, for the system to obtain data from the outputs. BEF# is used for flash memory bank selection. When BEF# and BES# are high, both banks are deselected and only standby power is consumed. OE# is the output control and is used to gate data from the output pins. The data bus is in high impedance state when OE# is high. Refer to Figure 6 for further details. SRAM Operation With BES# low and BEF# high, the SST32HF202/402/802 operate as 128K x16 CMOS SRAM, with fully static operation requiring no external clocks or timing strobes. The SST32HF202/402/802 SRAM is mapped into the first 128 KWord address space. When BES# and BEF# are high, both memory banks are deselected and the device enters standby mode. Read and Write cycle times are equal. The control signals UBS# and LBS# provide access to the upper data byte and lower data byte. See Table 3 for SRAM Read and Write data byte control modes of operation. (c)2008 Silicon Storage Technology, Inc. S71209-07-EOL 2 http://store.iiic.cc/ 02/08 Multi-Purpose Flash (MPF) + SRAM ComboMemory SST32HF202 / SST32HF402 / SST32HF802 EOL Data Sheet Flash Erase/Program Operation SST32HF202, A17-A15, for SST32HF402, and A18-A15, for SST32HF802, are used to determine the block address. The sector or block address is latched on the falling edge of the sixth WE# pulse, while the command (30H or 50H) is latched on the rising edge of the sixth WE# pulse. The internal Erase operation begins after the sixth WE# pulse. The End-of-Erase operation can be determined using either Data# Polling or Toggle Bit methods. See Figures 12 and 13 for timing waveforms. Any commands issued during the Sector- or Block-Erase operation are ignored. SDP commands are used to initiate the flash memory bank Program and Erase operations of the SST32HF202/402/ 802. SDP commands are loaded to the flash memory bank using standard microprocessor Write sequences. A command is loaded by asserting WE# low while keeping BEF# low and OE# high. The address is latched on the falling edge of WE# or BEF#, whichever occurs last. The data is latched on the rising edge of WE# or BEF#, whichever occurs first. Flash Chip-Erase Operation Flash Word-Program Operation The SST32HF202/402/802 provide a Chip-Erase operation, which allows the user to erase the entire memory array to the "1" state. This is useful when the entire device must be quickly erased. The flash memory bank of the SST32HF202/402/802 devices is programmed on a word-by-word basis. Before Program operations, the memory must be erased first. The Program operation consists of three steps. The Chip-Erase operation is initiated by executing a sixbyte command sequence with Chip-Erase command (10H) at address 5555H in the last byte sequence. The Erase operation begins with the rising edge of the sixth WE# or CE#, whichever occurs first. During the Erase operation, the only valid read is Toggle Bit or Data# Polling. See Table 4 for the command sequence, Figure 10 for timing diagram, and Figure 21 for the flowchart. Any commands issued during the Chip-Erase operation are ignored. The first step is the three-byte load sequence for Software Data Protection. The second step is to load word address and word data. During the Word-Program operation, the addresses are latched on the falling edge of either BEF# or WE#, whichever occurs last. The data is latched on the rising edge of either BEF# or WE#, whichever occurs first. The third step is the internal Program operation which is initiated after the rising edge of the fourth WE# or BEF#, whichever occurs first. The Program operation, once initiated, will be completed, within 20 s. See Figures 7 and 8 for WE# and BEF# controlled Program operation timing diagrams and Figure 18 for flowcharts. During the Program operation, the only valid flash Read operations are Data# Polling and Toggle Bit. During the internal Program operation, the host is free to perform additional tasks. Any SDP commands loaded during the internal Program operation will be ignored. Write Operation Status Detection Flash Sector/Block-Erase Operation The actual completion of the nonvolatile write is asynchronous with the system; therefore, either a Data# Polling or Toggle Bit read may be simultaneous with the completion of the Write cycle. If this occurs, the system may possibly get an erroneous result, i.e., valid data may appear to conflict with either DQ7 or DQ6. In order to prevent spurious rejection, if an erroneous result occurs, the software routine should include a loop to read the accessed location an additional two (2) times. If both reads are valid, then the device has completed the Write cycle, otherwise the rejection is valid. The SST32HF202/402/802 provide two software means to detect the completion of a Write (Program or Erase) cycle, in order to optimize the system Write cycle time. The software detection includes two status bits: Data# Polling (DQ7) and Toggle Bit (DQ6). The End-of-Write detection mode is enabled after the rising edge of WE#, which initiates the internal Program or Erase operation. The Flash Sector/Block-Erase operation allows the system to erase the device on a sector-by-sector (or block-byblock) basis. The SST32HF202/402/802 offer both SectorErase and Block-Erase mode. The sector architecture is based on uniform sector size of 2 KWord. The Block-Erase mode is based on uniform block size of 32 KWord. The Sector-Erase operation is initiated by executing a six-byte command sequence with Sector-Erase command (30H) and sector address (SA) in the last bus cycle. The address lines A16-A11, for SST32HF202, A17-A11, for SST32HF402, and A18-A11, for SST32HF802, are used to determine the sector address. The Block-Erase operation is initiated by executing a six-byte command sequence with Block-Erase command (50H) and block address (BA) in the last bus cycle. The address lines A16-A15, for (c)2008 Silicon Storage Technology, Inc. S71209-07-EOL 3 http://store.iiic.cc/ 02/08 Multi-Purpose Flash (MPF) + SRAM ComboMemory SST32HF202 / SST32HF402 / SST32HF802 EOL Data Sheet Flash Data# Polling (DQ7) Flash Software Data Protection (SDP) When the SST32HF202/402/802 flash memory banks are in the internal Program operation, any attempt to read DQ7 will produce the complement of the true data. Once the Program operation is completed, DQ7 will produce true data. Note that even though DQ7 may have valid data immediately following the completion of an internal Write operation, the remaining data outputs may still be invalid: valid data on the entire data bus will appear in subsequent successive Read cycles, after an interval of 1 s. During internal Erase operation, any attempt to read DQ7 will produce a `0'. Once the internal Erase operation is completed, DQ7 will produce a `1'. The Data# Polling is valid after the rising edge of the fourth WE# (or BEF#) pulse for Program operation. For Sector- or Block-Erase, the Data# Polling is valid after the rising edge of the sixth WE# (or BEF#) pulse. See Figure 9 for Data# Polling timing diagram and Figure 19 for a flowchart. The SST32HF202/402/802 provide the JEDEC approved software data protection scheme for all flash memory bank data alteration operations, i.e., Program and Erase. Any Program operation requires the inclusion of a series of three-byte sequence. The three-byte load sequence is used to initiate the Program operation, providing optimal protection from inadvertent Write operations, e.g., during the system power-up or power-down. Any Erase operation requires the inclusion of six-byte load sequence. The SST32HF202/402/802 devices are shipped with the software data protection permanently enabled. See Table 4 for the specific software command codes. During SDP command sequence, invalid SDP commands will abort the device to the Read mode, within Read cycle time (TRC). Concurrent Read and Write Operations The SST32HF202/402/802 provide the unique benefit of being able to read from or write to SRAM, while simultaneously erasing or programming the Flash. This allows data alteration code to be executed from SRAM, while altering the data in Flash. The following table lists all valid states. Flash Toggle Bit (DQ6) During the internal Program or Erase operation, any consecutive attempts to read DQ6 will produce alternating `1's and `0's, i.e., toggling between 1 and 0. When the internal Program or Erase operation is completed, the toggling will stop. The flash memory bank is then ready for the next operation. The Toggle Bit is valid after the rising edge of the fourth WE# (or BEF#) pulse for Program operation. For Sector- or Bank-Erase, the Toggle Bit is valid after the rising edge of the sixth WE# (or BEF#) pulse. See Figure 10 for Toggle Bit timing diagram and Figure 19 for a flowchart. CONCURRENT READ/WRITE STATE TABLE Flash Program/Erase Program/Erase SRAM Read Write The device will ignore all SDP commands when an Erase or Program operation is in progress. Note that Product Identification commands use SDP; therefore, these commands will also be ignored while an Erase or Program operation is in progress. Flash Memory Data Protection The SST32HF202/402/802 flash memory bank provides both hardware and software features to protect nonvolatile data from inadvertent writes. Flash Hardware Data Protection Noise/Glitch Protection: A WE# or BEF# pulse of less than 5 ns will not initiate a Write cycle. VDD Power Up/Down Detection: The Write operation is inhibited when VDD is less than 1.5V. Write Inhibit Mode: Forcing OE# low, BEF# high, or WE# high will inhibit the Flash Write operation. This prevents inadvertent writes during power-up or power-down. (c)2008 Silicon Storage Technology, Inc. S71209-07-EOL 4 http://store.iiic.cc/ 02/08 Multi-Purpose Flash (MPF) + SRAM ComboMemory SST32HF202 / SST32HF402 / SST32HF802 EOL Data Sheet Product Identification Product Identification Mode Exit/Reset The Product Identification mode identifies the devices as the SST32HF202/402/802 and manufacturer as SST. This mode may be accessed by software operations only. The hardware device ID Read operation, which is typically used by programmers, cannot be used on this device because of the shared lines between flash and SRAM in the multi-chip package. Therefore, application of high voltage to pin A9 may damage this device. Users may use the software Product Identification operation to identify the part (i.e., using the device ID) when using multiple manufacturers in the same socket. For details, see Tables 3 and 4 for software operation, Figure 14 for the software ID entry and Read timing diagram, and Figure 20 for the ID entry command sequence flowchart. In order to return to the standard read mode, the Software Product Identification mode must be exited. Exiting is accomplished by issuing the Exit ID command sequence, which returns the device to the Read operation. Please note that the software reset command is ignored during an internal Program or Erase operation. See Table 4 for software command codes, Figure 15 for timing waveform and Figure 20 for a flowchart. Design Considerations SST recommends a high frequency 0.1 F ceramic capacitor to be placed as close as possible between VDD and VSS, e.g., less than 1 cm away from the VDD pin of the device. Additionally, a low frequency 4.7 F electrolytic capacitor from VDD to VSS should be placed within 1 cm of the VDD pin.
