HY62SF16804B Datasheet, PDF (2/10 Pages) Hynix Semiconductor – 512K x16 bit 1.8V Super Low Power Full CMOS slow SRAM

HY62SF16804B
DESCRIPTION
The HY62SF16804B is a high speed, super low
power and 8Mbit full CMOS SRAM organized as
512K words by 16bits. The HY62SF16804B 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.
