DESCRIPTION
The XM20C64 is a high speed nonvolatile RAM Module.
It is comprised of four Xicor X20C16 high speed
NOVRAMs, a high speed decoder and decoupling
capacitors mounted on a co-fired multilayered Ceramic
substrate. The XM20C64 is configured 8K x 8 and is fully
decoded. The module is a 28-lead DIP conforming to the
industry standard pinout for SRAMs.
The XM20C64 fully supports the AUTOSTORE feature,
providing hands-off automatic storing of RAM data
into E
2
PROM when V
CC
falls below the AUTOSTORE
threshold.
The XM20C64 is a highly reliable memory component,
supporting unlimited writes to RAM, a minimum 1,000,000
store cycles and a minimum 100 year data retention.
