The AS6C62256 is a 262,144-bit low power CMOS
static random access memory organized as 32,768
words by 8 bits. It is fabricated using very high
performance, high reliability CMOS technology. Its
standby current is stable within the range of
operating temperature.
The AS6C62256 is well designed for low power
application, and particularly well suited for battery
back-up nonvolatile memory application.
The AS6C62256 operates with wide range power
supply 2.7 ~ 5.5V
