Flash Program Operation
These devices programmed word-by-word byte-by-byte basis depending state CIOF pin. Before programming, must ensure that sector being programmed fully erased. Program operation accomplished three steps: Software Data Protection initiated using three-byte load sequence. Address data loaded. During Program operation, addresses latched falling edge either BEF# WE#, whichever occurs last. data latched rising edge either BEF# WE#, whichever occurs first. internal Program operation initiated after rising edge fourth BEF#, whichever occurs first. Program operation, once initiated, will completed typically within Figures BEF# 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.
Flash Chip-Erase Operation
SST34HF3244/3282/3284 provide Chip-Erase operation, which allows user erase flash sectors/blocks state. This useful when device must quickly erased. Chip-Erase operation initiated executing sixbyte command sequence with Chip-Erase command (10H) address 555H last byte sequence. Erase operation begins with rising edge sixth BEF#, whichever occurs first. During Erase operation, only valid read Toggle Bits Data# Polling. Table command sequence, Figure timing diagram, Figure flowchart. commands issued during Chip-Erase operation ignored. When low, attempt Chip-Erase will ignored.
Flash Erase-Suspend/-Resume Operations
Erase-Suspend operation temporarily suspends Sector- Block-Erase operation thus allowing data read from memory location, program data into sector/block that suspended Erase operation. operation executed issuing one-byte command sequence with Erase-Suspend command (B0H). device automatically enters read mode more than after Erase-Suspend command been issued. (TES maximum latency equals µs.) Valid data read from sector block that suspended from Erase operation. Reading address location within erasesuspended sectors/blocks will output toggling "1". While Erase-Suspend mode, Program operation allowed except sector block selected Erase-Suspend. resume Sector-Erase BlockErase operation which been suspended, system must issue Erase-Resume command. operation executed issuing one-byte command sequence with Erase Resume command (30H) address onebyte sequence.

device includes CIOF control whether device data pins operate x16. CIOF logic (VIH) device data configuration: data pins DQ0-DQ15 active controlled BEF# OE#. CIOF logic "0", device data configuration: only data pins DQ0-DQ7 active controlled BEF# OE#. remaining data pins DQ8DQ14 Hi-Z, while DQ15 used address input Least Significant address bus.
Flash Data# Polling (DQ7)
When devices internal Program operation, attempt read will produce complement true data. Once Program operation completed, will produce true data. During internal Erase operation, attempt read will produce `0'. Once internal Erase operation completed, will produce `1'. Data# Polling valid after rising edge fourth BEF#) pulse Program operation. Sector-, Block-, Chip-Erase, Data# Polling valid after rising edge sixth BEF#) pulse. Figure Data# Polling (DQ7) timing diagram Figure flowchart.
Ready/Busy# (RY/BY#)
SST34HF3244/3282/3284 include Ready/Busy# (RY/BY#) output signal. RY/BY# open drain output that indicates whether Erase Program operation progress. Since RY/BY# open drain output, allows several devices tied parallel external pull-up resistor. After rising edge final pulse command sequence, RY/BY# status valid. When RY/BY# actively pulled low, indicates that Erase Program operation progress. When RY/BY# high (Ready), devices read left standby mode.
