Read Read operations SST29EE020A/29LE020A/ 29VE020A 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. Refer read cycle timing diagram further details (Figure Write Page Write SST29EE020A/29LE020A/ 29VE020A uses JEDEC Standard Software Data Protection (SDP) three-byte command sequence. Write operation consists three steps. Step three-byte load sequence Software Data Protection. Step byte-load cycle page buffer SST29EE020A/29LE020A/29VE020A. Steps same timing both operations. Step internally controlled write cycle writing data loaded page buffer into memory array nonvolatile storage. During both three-byte load sequence byte-load cycle, addresses latched falling edge either WE#, whichever occurs last. data latched rising edge either WE#, whichever occurs first. internal write cycle initiated TBLCO timer after rising edge CE#, whichever occurs first. write cycle, once initiated, will continue completion, typically within Figures controlled page write cycle timing diagrams Figures flowcharts. Write operation three functional cycles: Software Data Protection load sequence, page load cycle, internal write cycle. Software Data Protection consists specific three-byte load sequence that allows writing selected page will leave SST29EE020A/29LE020A/29VE020A protected Page Write. page load cycle consists loading bytes data into page buffer. internal write cycle consists TBLCO time-out write timer operation. During Write operation, only valid reads Data# Polling Toggle Bit. Page Write operation allows loading bytes data into page buffer SST29EE020A/ 29LE020A/29VE020A before initiation internal write cycle. During internal write cycle, data page buffer written simultaneously into memory array. Hence, page write feature SST29EE020A/ 29LE020A/29VE020A allow entire memory written little seconds. During internal write cycle, host free perform additional tasks, such fetch data from other locations system write next page. each Page Write operation, bytes that loaded into page buffer must have same page address, i.e. through A16. byte loaded with user data will written Figures page write cycle timing diagrams. after completion three-byte load sequence, host loads second byte into page buffer within byte-load cycle time (TBLC) SST29EE020A/29LE020A/29VE020A will stay page load cycle. Additional bytes then loaded consecutively. page load cycle will terminated additional byte loaded into page buffer within (TBLCO) from last byte-load cycle, i.e., subsequent high-to-low transition after last rising edge CE#. Data page buffer changed subsequent byte-load cycle. page load period continue indefinitely, long host continues load device within byte-load cycle time page loaded determined page address last byte loaded. Software Chip Erase SST29EE020A/29LE020A/29VE020A provide Chip Erase operation, which allows user simultaneously clear entire memory array state. This useful when entire device must quickly erased. Software Chip Erase operation initiated using specific six-byte load sequence. After load sequence, device enters into internally timed cycle similar write cycle. During Erase operation, only valid read Toggle Bit. Table load sequence, Figure timing diagram, Figure flowchart.

Write Operation Status Detection SST29EE020A/29LE020A/29VE020A provide software means detect completion write cycle, order optimize system write cycle time. software detection includes status bits: Data# Polling (DQ7) Toggle (DQ6). write detection mode enabled after rising whichever occurs first, which initiates internal write cycle. actual completion nonvolatile write asynchronous with system; therefore, either Data# Polling Toggle read simultaneous with completion write cycle. this occurs, system possibly erroneous result, i.e., valid data appear conflict with either DQ6. order prevent spurious rejection, erroneous result occurs, software routine should include loop read accessed location additional times. both reads valid, then device completed write cycle, otherwise rejection valid. Data# Polling (DQ7) When SST29EE020A/29LE020A/29VE020A internal write cycle, attempt read last byte loaded during byte-load cycle will receive complement true data. Once write cycle completed, will show true data. device then ready next operation. Figure Data# Polling timing diagram Figure flowchart. Toggle (DQ6) During internal write cycle, consecutive attempts read will produce alternating 1's, i.e., toggling between When write cycle completed, toggling will stop. device then ready next operation. Figure Toggle timing diagram Figure flowchart. initial read Toggle will typically "1". Data Protection SST29EE020A/29LE020A/29VE020A provide 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 2.5V. Write Inhibit Mode: Forcing low, high, high will inhibit write operation. This prevents inadvertent writes during power-up power-down. Software Data Protection (SDP) SST29EE020A/29LE020A/29VE020A provide JEDEC approved software data protection scheme data alteration operations, i.e., Write Chip Erase. With this scheme, write operation requires inclusion series three byte-load operations precede data loading operation. three byte-load sequence used initiate write cycle, providing optimal protection from inadvertent write operations, e.g., during system power-up power-down.
