32Kx8 LP SRAM EM6132K800W Series
GENERAL DESCRIPTION
The EM6132K800W 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 EM6132K800W is well designed for low power application, and particularly well suited for battery
back-up nonvolatile memory application.
The EM6132K800W operates from a single power supply of 2.7V ~ 5.5V and all inputs and outputs are
fully TTL compatible
