GM76C256C Series

DESCRIPTION

FEATURES

The GM76C256C is a high-speed, low power and

32,786 X 8-bits CMOS Static Random Access

Fully static operation and Tri-state output

TTL compatible inputs and outputs

Low power consumption

Battery backup(L/LL-part)

- 2.0V(min.) data retention

Standard pin configuration

- 28 pin 600mil PDIP

- 28 pin 330mil SOP

- 28 pin 8x13.4 mm TSOP-I

(Standard)

Memory fabricated using

Hynix's high

performance CMOS process technology. It is

suitable for use in low voltage operation and

battery back-up application. This device has a

data retention mode that guarantees data to

remain valid at the minimum power supply

voltage of 2.0 volt.
