SL29321-90 SL29321-90(T/G)(V/R/S) 8M X 32 Bits (32MB) Flash Memory Module (5.0V Only) FEATURES GENERAL DESCRIPTION · · · · · · The SiliconTech SL29321-90 SL29321-90(T/G)(V/R/S) is a 8M x 32 bits flash 80-pin Single In-line Memory Module (SIMM). This module consists of eight 4M x 8 bits CMOS flash memory in 40-pin TSOP packages mounted on an 80-pin glass epoxy substrate. Decoupling capacitors of 0.1µF are also mounted. · · Access Time of 90ns TTL compatible inputs and outputs 5.0V only power supply (+5.0V±10%) JEDEC standard Tin (option "T") or gold (option "G") edge connectors Three power on reset options - No power on reset: RST tied to VCC (Option "V") - Power on reset: RST tied to power supervisor circuit (Option "R") - System control of power on reset: RST tied to pin 7 (Option "S"; this option is not JEDEC standard) AMD Part Number Am29F032B-90EC Am29F032B-90EC flash memory components Minimum 1,000,000 write/erase cycles per sector Option "T" provides tin edge connectors and option "G" provides gold edge connectors. Option "R" provides power on reset through a power supervisor circuit; option "S" provides system control of power on reset by connecting the reset signals to Pin 7; and, option "V" provides no power on reset. The module is intended for mounting into 80-pin edge connector sockets. The module uses the standard programming algorithms for AMD Am29F032B-90EC Am29F032B-90EC flash memory components.
