The split-gate cell design and thick oxide tun- neling injector attain better reliability and manufacturability compared with alternate approaches. The SST39SF010A/020A/040 devices write (Program or Erase) with a 4.5-5.5V power supply. The SST39SF010A/020A/040 devices conform to JEDEC standard pinouts for x8 memories. Featuring high performance Byte-Program, the SST39SF010A/020A/040 devices provide a maximum Byte-Program time of 20 µsec. These devices use Toggle Bit or Data# Polling to indicate the comple- tion of Program operation. To protect against inadvertent write, they have on-chip hardware and Soft- ware Data Protection schemes. Designed, manufactured, and tested for a wide spectrum of applications, these devices are offered with a guaranteed typical endurance of 100,000 cycles. Data retention is rated at greater than 100 years. The SST39SF010A/020A/040 devices are suited for applications that require convenient and econom- ical updating of program, configuration, or data memory. For all system applications, they significantly improve 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 Pro- gram times increase with accumulated Erase/Program cycles. To meet high density, surface mount requirements, the SST39SF010A/020A/040 are offered in 32-lead PLCC and 32-lead TSOP packages. A 600 mil, 32-pin PDIP is also available.

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 SST39SF010A/020A/040 is 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 (Figure 5) for further details. Byte-Program Operation The SST39SF010A/020A/040 are programmed on a byte-by-byte basis. Before programming, the sec- tor 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 fall- ing 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 µs. See Figures 6 and 7 for WE# and CE# controlled Program operation timing diagrams and Figure 16 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 per- form 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 load sequence for Software Data Protection with Sector-Erase com- mand (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 deter- mined using either Data# Polling or Toggle Bit methods. See Figure 10 for timing waveforms. Any com- mands written during the Sector-Erase operation will be ignored. Chip-Erase Operation The SST39SF010A/020A/040 provide Chip-Erase operation, which allows the user to erase the entire memory array to the “1s” 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 internal Erase operation, the only valid read is Toggle Bit or Data# Polling. See Table 4 for the com- mand sequence, Figure 11 for timing diagram, and Figure 19 for the flowchart. Any commands written during the Chip-Erase operation will be ignored. ©2011 Silicon Storage Technology, Inc. DS25022A 07/11 7 1 Mbit / 2 Mbit / 4 Mbit Multi-Purpose Flash SST39SF010A / SST39SF020A / SST39SF040 A Microchip Technology Company Data Sheet Write Operation Status Detection The SST39SF010A/020A/040 provide two software means to detect the completion of a Write (Pro- gram or Erase) cycle, in order to optimize the system Write cycle time. The software detection includes two status bits: Data# Polling (DQ ) and Toggle Bit (DQ ). The End-of-Write detection mode is enabled 7 6 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 DQ or DQ . In order to prevent spurious rejection, if an erroneous result occurs, the software 7 6 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. Data# Polling (DQ ) 7 When the SST39SF010A/020A/040 are in the internal Program operation, any attempt to read DQ will 7 produce the complement of the true data. Once the Program operation is completed, DQ will produce 7 true data. Note that even though DQ mayhave valid data immediately following the completion of an 7 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 µs. During internal Erase operation, any attempt to read DQ will produce a ‘0’. Once the internal Erase operation is completed, 7 DQ will produce a ‘1’. The Data# Polling is valid after the rising edge of fourth WE# (or CE#) pulse for 7 Program operation. For Sector- or Chip-Erase, the Data# Polling is valid after the rising edge of sixth WE# (or CE#) pulse. See Figure 8 for Data# Polling timing diagram and Figure 17 for a flowchart. Toggle Bit (DQ ) 6 During the internal Program or Erase operation, any consecutive attempts to read DQ will produce 6 alternating 0s and 1s, 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 Chip-Erase, the Toggle Bit is valid after the rising edge of sixth WE# (or CE#) pulse. See Figure 9 for Toggle Bit tim- ing diagram and Figure 17 for a flowchart. Data Protection The SST39SF010A/020A/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. V Power Up/Down Detection: The Write operation is inhibited when V is less than 2.5V. DD DD Write Inhibit Mode: Forcing OE# low, CE# high, or WE# high will inhibit the Write operation. This pre- vents inadvertent writes during power-up or power-down. ©2011 Silicon Storage Technology, Inc. DS25022A 07/11 8 1 Mbit / 2 Mbit / 4 Mbit Multi-Purpose Flash SST39SF010A / SST39SF020A / SST39SF040 A Microchip Technology Company Data Sheet Software Data Protection (SDP) The SST39SF010A/020A/040 provide the JEDEC approved Software Data Protection scheme for all 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 SST39SF010A/020A/040 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 T RC. Product Identification The Product Identification mode identifies the device as the SST39SF040, SST39SF010A, or SST39SF020A and manufacturer as SST. This mode may be accessed by software operations. Users may wish to 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, Table 4 for software operation, Figure 12 for the software ID entry and read timing diagram and Figure 18 for the ID entry command sequence flowchart.

Exit 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.
