Mbit Dual-Bank Flash Mbit SRAM ComboMemory SST34HF162C SST34HF164C Device Operation SST34HF162C/164C BES# BEF# control operation either flash SRAM memory bank. When BEF# low, flash bank activated Read, Program Erase operation. When BES# SRAM activated Read Write operation. BEF# BES# cannot level same time. bank enable signals asserted, contention will result device suffer permanent damage. address, data, control lines shared flash SRAM memory banks which minimizes power consumption loading. device goes into standby when BEF# BES# bank enables raised VIHC (Logic High) when BEF# high. Flash Program Operation These devices programmed word-by-word basis. Before programming, must ensure that sector which 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. Concurrent Read/Write Operation SST34HF162C/164C provide unique benefit being able read from write SRAM, while simultaneously erasing programming flash. This allows data alteration code executed from SRAM, while altering data flash. following table lists valid states. CONCURRENT READ/WRITE STATE TABLE Flash Program/Erase Program/Erase SRAM Read Write device will ignore commands when Erase Program operation progress. Note that Product Identification commands SDP; therefore, these commands will also ignored while Erase Program operation progress. Flash Sector- /Block-Erase Operation 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 (30H) sector address (SA) last cycle. Block-Erase operation initiated 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. commands issued during Block- SectorErase operation ignored except Erase-Suspend Erase-Resume.

Data Protection SST34HF162C/164C 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.
