PRODUCT DESCRIPTION
The SST31LF041/041A/043/043A devices are a 512K x8 CMOS flash memory bank bined with a 128K x8 or 32K x8 CMOS SRAM memory bank manufactured with SST’s proprietary, high performance Super Flash technology. The SST31LF041/041A/043/043A devices write (SRAM or flash) with a 3.0-3.6V power supply. The monolithic SST31LF041/041A/043/043A devices conform to Software Data Protect (SDP) mands for x8 EEPROMs. Featuring high performance Byte-Program, the flash memory bank provides a maximum Byte-Program time of 20 µsec. The entire flash memory bank can be erased and programmed byte-by-byte in typically 8 seconds, when using interface features such as Toggle Bit or Data# Polling to indicate the pletion of Program operation. To protect against inadvertent flash write, the SST31LF041/041A/...
