Concurrent Read/Write Operation
Dual bank architecture SST34HF32A4 devices allows Concurrent Read/Write operation whereby user read from bank while programming erasing other bank. This operation used when user needs read system code bank while updating data other bank. Table dual-bank memory organization. Concurrent Read/Write States

Device Operation
SST34HF32A4 uses BES1#, BES2 BEF# control operation either flash PSRAM memory bank. When BEF# low, flash bank activated Read, Program Erase operation. When BES1# low, BES2 high PSRAM activated Read Write operation. BEF# BES1# cannot level, BES2 cannot high level same time. bank enable signals asserted, contention will result device suffer permanent damage. address, data, control lines shared flash PSRAM memory banks which minimizes power consumption loading. device goes into standby when BEF# BES1# bank enables raised VIHC (Logic High) when BEF# high BES2 low.

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
SST34HF32A4 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 within after Erase-Suspend command been issued. Valid data read from sector block that suspended from Erase operation. Reading address location within erase-suspended sectors/blocks will output toggling "1". While Erase-Suspend mode, Program operation allowed except sector block selected Erase-Suspend. resume Sector-Erase Block-Erase operation which been suspended, system must issue Erase-Resume command. operation executed issuing one-byte command sequence with Erase Resume command (30H) address one-byte sequence.

These devices offer both Sector-Erase Block-Erase operations. These operations allow system erase devices sector-by-sector block-by-block) basis. sector architecture based uniform sector size KWord. Block-Erase mode based uniform block size KWord. Sector-Erase operation initiated executing six-byte command sequence with Sector-Erase command (50H) sector address (SA) last cycle. Block-Erase operation initiated executing six-byte command sequence with Block-Erase command (30H) 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. commands issued during Block- SectorErase operation ignored except Erase-Suspend Erase-Resume.

Flash Write Operation Status Detection
SST34HF32A4 provide hardware software means detect completion Write (Program Erase) cycle, order optimize system Write cycle time. hardware detection uses Ready/ Busy# (RY/BY#) pin. 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. actual completion nonvolatile write asynchronous with system; therefore, either Ready/Busy# (RY/ BY#), Data# Polling (DQ7) Toggle (DQ6) 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.

This function, found only 56-ball package, 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#)
SST34HF32A4 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.

Data Protection
SST34HF32A4 provide both hardware software features protect nonvolatile data from inadvertent writes.
Hardware Data Protection
Noise/Glitch Protection: BEF# pulse less than will initiate Write cycle. Power Up/Down Detection: Write operation inhibited when less than 1.5V. Write Inhibit Mode: Forcing low, BEF# high, high will inhibit Write operation. This prevents inadvertent writes during power-up power-down.
Hardware Block Protection
SST34HF32A4 provide hardware block protection which protects outermost KWord Bank block protected when held low. user disable block protection driving high thus allowing erase program data into protected sectors. must held high prior issuing write command remain stable until after entire Write operation completed.
