HY62UF16400A Series
256Kx16bit full CMOS SRAM
DESCRIPTION
The HY62UF16400A is a high speed, super low
power and 4Mbit full CMOS SRAM organized as
256K words by 16bits. The HY62UF16400A uses
high performance full CMOS process technology
and is designed for high speed and low power
circuit technology. It is particularly well-suited for
the high density low power system application.
This device has a data retention mode that
guarantees data to remain valid at a minimum
power supply voltage of 1.2V.
FEATURES
•
Fully static operation and Tri-state output
•
TTL compatible inputs and outputs
•
Battery backup
-. 1.2V(min) data retention
•
