The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches. The SST39LF010/020/040 devices write (Program or Erase) with a 3.0-3.6V power supply. The SST39VF010/020/040 devices write with a 2.7-3.6V power supply. The devices conform to JEDEC standard pinouts for x8 memories. Featuring high performance Byte-Program, the SST39LF010/020/040 and SST39VF010/020/040 devices provide a maximum Byte-Program time of 20 sec. These devices use Toggle Bit or Data# Polling to indicate the completion of Program operation. To protect against inadvertent write, they have on-chip hardware and Software Data Protection schemes. Designed, manufactured, and tested for a wide spectrum of applications, they are offered with a guaranteed typical endurance of 100,000 cycles. Data retention is rated at greater than 100 years. The SST39LF010/020/040 and SST39VF010/020/040 devices are suited for applications that require convenient and economical updating of program, configuration, or data memory. For all system applications, they significantly improves performance and reliability, while lowering power consumption. They 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. These devices also improve flexibility while lowering the cost for program, data, and configuration storage applications. 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. To meet surface mount requirements, the SST39LF010/020/040 and SST39VF010/020/040 devices are offered in 32-lead PLCC and 32-lead TSOP packages. The SST39LF/VF010 and SST39LF/VF020 are also offered in a 48-ball TFBGA package. See Figures 2, 3, 4, and 5 for pin assignments. (c)2011 Silicon Storage Technology, Inc.

Commands are written to the device using standard microprocessor write sequences. A command is written by asserting WE# low while keeping CE# low. The address bus is latched on the falling edge of WE# or CE#, whichever occurs last. The data bus is latched on the rising edge of WE# or CE#, whichever occurs first. Read The Read operation of the SST39LF010/020/040 and SST39VF010/020/040 devices are controlled by CE# and OE#, both have to be low for the system to obtain data from the outputs. CE# is used for device selection. When CE# is high, the chip is 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 either CE# or OE# is high. Refer to the Read cycle timing diagram for further details (Figure 6). Byte-Program Operation The SST39LF010/020/040 and SST39VF010/020/040 are programmed on a byte-by-byte basis. Before programming, the sector where the byte exists must be fully erased. The Program operation is accomplished in three steps. The first step is the three-byte load sequence for Software Data Protection. The second step is to load byte address and byte data. During the Byte-Program operation, the addresses are latched on the falling edge of either CE# or WE#, whichever occurs last. The data is latched on the rising edge of either CE# 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 CE#, whichever occurs first. The Program operation, once initiated, will be completed, within 20 s. See Figures 7 and 8 for WE# and CE# controlled Program operation timing diagrams and Figure 17 for flowcharts. During the Program operation, the only valid reads are Data# Polling and Toggle Bit. During the internal Program operation, the host is free to perform additional tasks. Any commands written during the internal Program operation will be ignored. Sector-Erase Operation The Sector-Erase operation allows the system to erase the device on a sector-by-sector basis. The sector architecture is based on uniform sector size of 4 KByte. 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 sector address is latched on the falling edge of the sixth WE# pulse, while the command (30H) 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 can be determined using either Data# Polling or Toggle Bit methods. See Figure 11 for timing waveforms. Any commands written during the Sector-Erase operation will be ignored. Chip-Erase Operation The SST39LF010/020/040 and SST39VF010/020/040 devices provide a Chip-Erase operation, which allows the user to erase the entire memory array to the `1's state. This is useful when the entire device must be quickly erased. The Chip-Erase operation is initiated by executing a six- byte Software Data Protection command sequence with Chip-Erase command (10H) with address 5555H in the last byte sequence. The internal Erase operation begins with the rising edge of the sixth WE# or CE#, whichever occurs first. During the (c)2011 Silicon Storage Technology, Inc. DS25023A 7 08/11 1 Mbit / 2 Mbit / 4 Mbit Multi-Purpose Flash A Microchip Technology Company SST39LF010 / SST39LF020 / SST39LF040 SST39VF010 / SST39VF020 / SST39VF040 Data Sheet internal Erase operation, the only valid read is Toggle Bit or Data# Polling. See Table 4 for the command sequence, Figure 12 for timing diagram, and Figure 20 for the flowchart. Any commands written during the Chip-Erase operation will be ignored. Write Operation Status Detection The SST39LF010/020/040 and SST39VF010/020/040 devices 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-ofWrite detection mode is enabled after the rising edge of WE# which initiates the internal Program or 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. (c)2011 Silicon Storage Technology, Inc. DS25023A 8 08/11 1 Mbit / 2 Mbit / 4 Mbit Multi-Purpose Flash A Microchip Technology Company SST39LF010 / SST39LF020 / SST39LF040 SST39VF010 / SST39VF020 / SST39VF040 Data Sheet Data# Polling (DQ7) When the SST39LF010/020/040 and SST39VF010/020/040 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 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 fourth WE# (or CE#) pulse for Program operation. For Sector- or Chip-Erase, the Data# Polling is valid after the rising edge of sixth WE# (or CE#) pulse. See Figure 9 for Data# Polling timing diagram and Figure 18 for a flowchart. Toggle Bit (DQ6) During the internal Program or Erase operation, any consecutive attempts to read DQ6 will produce alternating `0's and `1's, i.e., toggling between 0 and 1. When the internal Program or Erase operation is completed, the toggling will stop. The device is then ready for the next operation. The Toggle Bit is valid after the rising edge of fourth WE# (or CE#) pulse for Program operation. For Sector- or ChipErase, the Toggle Bit is valid after the rising edge of sixth WE# (or CE#) pulse. See Figure 10 for Toggle Bit timing diagram and Figure 18 for a flowchart. Data Protection The SST39LF010/020/040 and SST39VF010/020/040 provide both hardware and software features to protect nonvolatile data from inadvertent writes. Hardware Data Protection Noise/Glitch Protection: A WE# or CE# 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, CE# high, or WE# high will inhibit the Write operation. This prevents inadvertent writes during power-up or power-down. (c)2011 Silicon Storage Technology, Inc.

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. These devices are shipped with the Software Data Protection permanently enabled. See Table 4 for the specific software command codes. During SDP command sequence, invalid commands will abort the device to read mode, within TRC. Product Identification The Product Identification mode identifies the devices as the SST39LF/VF010, SST39LF/VF020, and SST39LF/VF040 and manufacturer as SST. This mode may be accessed by software operations. 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 Table 4 for software operation, Figure 13 for the Software ID Entry and Read timing diagram, and Figure 19 for the Software ID entry command sequence flowchart.

Exit is accomplished by issuing the Software ID Exit command sequence, which returns the device to the Read operation. Please note that the Software ID Exit command is ignored during an internal Program or Erase operation.
