EM6156K1600V fiche technique
256Kx16 LP SRAM EM6156K600V Series
GENERAL DESCRIPTION
The EM6156K600V is a 4,194,304-bit low power CMOS static random access memory organized as
262,144 words by 16 bits. It is fabricated using very high performance, high reliability CMOS
technology. Its standby current is stable within the range of operating temperature.
The EM6156K600V is well designed for low power application, and particularly well suited for battery
back-up nonvolatile memory application.
The EM6156K600V operates from a single power supply of 2.7V ~ 3.6V and all inputs and outputs are
fully TTL compatible
