Hyundai Semiconductor

HY628100A Series

128Kx8bit CMOS SRAM

DESCRIPTION

The HY628100A is a high speed, low power and

1M bit CMOS Static Random Access Memory

organized

as

131,072

words

by

8bit.

The

HY628100A

uses

high

performance

CMOS

process technology and designed for high speed

low power circuit technology. It is particulary well

suited for used in 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 2.0V.

FEATURES

• Fully static operation and Tri-state output

• TTL compatible inputs and outputs

• Battery backup(L/LL-part)

- 2.0V(min) data retention

• Standard pin configuration

- 32pin 525mil SOP

- 32pin 8x20mm TSOP-I(Standard)
