HY62UF8400A Series
512Kx8bit full CMOS SRAM
DESCRIPTION
The HY62UF8400A is a high speed, super low
power and 4Mbit full CMOS SRAM organized as
512K words by 8bits. The HY62UF8400A 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
