during Erase Program than alternative flash technologies. When programming flash device, total energy consumed function applied voltage, current, time application. given voltage range, SuperFlash technology uses less current program shorter erase time; therefore, total energy consumed during Erase Program operation less than alternative flash technologies. These devices also improve flexibility while lowering cost program, data, configuration storage applications. SuperFlash technology provides fixed Erase Program times independent number Erase/Program cycles that have occurred. Consequently, system software hardware does have modified de-rated necessary with alternative flash technologies, whose Erase Program times increase with accumulated Erase/Program cycles. meet surface mount requirements, SST39WF800B offered 48-ball TFBGA package 48-ball MicroPackage.

Device Operation
Commands, which used initiate memory operation functions device, written device using standard microprocessor write sequences. command written asserting while keeping low. address latched falling edge CE#, whichever occurs last. data latched rising edge CE#, whichever occurs first.
Sector-/Block-Erase Operation
SST39WF800B offers both Sector-Erase BlockErase modes which allow system erase device sector-by-sector, block-by-block, basis. sector architecture based uniform sector size KWord. Initiate Sector-Erase operation executing six-byte command sequence with Sector-Erase command (30H) sector address (SA) last cycle. Block-Erase mode based uniform block size KWord. Initiate Block-Erase operation executing six-byte command sequence with Block-Erase command (50H) block address (BA) last cycle. sector block address latched falling edge sixth pulse, while command (30H 50H) latched rising edge sixth pulse. internal Erase operation begins after sixth pulse. End-of-Erase operation determined using either Data# Polling Toggle methods. Figures timing waveforms. commands issued during Sector- Block-Erase operation ignored.
Read
Read operation SST39WF800B controlled OE#; both have system obtain data from outputs. used device selection. When high, chip deselected only standby power consumed. output control used gate data from output pins. data high impedance state when either high. Figure
Word-Program Operation
SST39WF800B programmed word-by-word basis. sector where word exists must fully erased before programming. Programming accomplished three steps: Load three-byte sequence Software Data Protection. Load word address word data. During Word-Program operation, addresses latched falling edge either WE#, whichever occurs last. data latched rising edge either WE#, whichever occurs first. Initiate internal Program operation after rising edge fourth CE#, whichever occurs first. Once initiated, Program operation will completed within Figures controlled Program operation timing diagrams Figure flowcharts. During Program operation, only valid reads Data# Polling Toggle Bit. During internal Program operation, host free perform additional tasks. commands issued during internal Program operation ignored.
Chip-Erase Operation
SST39WF800B provides Chip-Erase operation, which allows user erase entire memory array state. This useful when entire device must quickly erased. Initiate Chip-Erase operation executing six-byte command sequence with Chip-Erase command (10H) address 5555H last byte sequence. Erase operation begins with rising edge sixth CE#, whichever occurs first. During Erase operation, only valid read Toggle Data# Polling. Table command sequence, Figure timing diagram, Figure flowchart. commands issued during Chip-Erase operation ignored.

Write Operation Status Detection
optimize system write cycle time, SST39WF800B provides software means detect completion Program Erase write cycle. software detection includes status bits-Data# Polling (DQ7) Toggle (DQ6). End-of-Write detection mode enabled after rising edge WE#, which initiates internal Program Erase operation. completion nonvolatile Write asynchronous with system; therefore, either Data# Polling Toggle read occur simultaneously with completion Write cycle. this occurs, system erroneous result, i.e., valid data appear conflict with either DQ6. prevent spurious rejection event erroneous result, software routine must include loop read accessed location additional times. both Reads valid, then device completed Write cycle, otherwise rejection valid.
Toggle valid after rising edge fourth CE#) pulse Program operation. Sector-, Blockor Chip-Erase, Toggle valid after rising edge sixth CE#) pulse. Figure Toggle timing diagram Figure flowchart.
Data Protection
SST39WF800B provides both hardware software features protect nonvolatile data from inadvertent writes.
Hardware Data Protection
Noise/Glitch Protection: pulse less than will initiate write cycle. Power Up/Down Detection: Write operation inhibited when less than 1.0V. Write Inhibit Mode: Forcing low, high, high will inhibit Write operation. This prevents inadvertent writes during power-up power-down.
Data# Polling (DQ7)
When SST39WF800B internal Program operation, attempt read will produce complement true data. Once Program operation complete, will produce true data. Although have valid data immediately following completion internal Write operation, remaining data outputs still invalid. Valid data entire data will appear subsequent successive Read cycles after interval During internal Erase operation, attempt read will produce `0'. Once internal Erase operation complete, will produce `1'. Data# Polling valid after rising edge fourth CE#) pulse Program operation. Sector-, Block-, Chip-Erase, Data# Polling valid after rising edge sixth CE#) pulse. Figure Data# Polling timing diagram Figure flowchart.
Software Data Protection (SDP)
SST39WF800B provides JEDEC approved Software Data Protection scheme data alteration operations, i.e., Program Erase. Program operation requires inclusion three-byte sequence. three-byte load sequence used initiate Program operation, providing optimal protection from inadvertent Write operations, e.g., during system power-up power-down. Erase operation requires inclusion six-byte sequence. This group devices shipped with Software Data Protection permanently enabled. Table specific software command codes. During command sequence, invalid commands will abort device Read mode within TRC. contents DQ15DQ8 VIH, other value, during command sequence.
Common Flash Memory Interface (CFI)
SST39WF800A contains information that describes characteristics device, supports both original Query mode implementation compatibility with existing devices, well general Query mode. enter Query mode, system must write three-byte sequence, same Product Entry command, with (CFI Query command) address 5555H last byte sequence.
Toggle (DQ6)
During internal Program Erase operation, consecutive attempts read will produce alternating `1's `0's, i.e., toggling between `0'. When Program Erase operation complete, will stop toggling device ready next operation.
