HM628128A Series

131,072-word

× 8-bit High Speed CMOS Static RAM

Rev. X

January 1995

The Hitachi HM628128A is a CMOS static RAM

organized 128 kword

× 8 bit. It realizes higher

density, higher performance and low power

consumption by employing 0.8 µm Hi-CMOS

process technology.

It offers low power standby power dissipation;

therefore, it is suitable for battery back-up systems.

The device, packaged in a 525-mil SOP (460-mil

body SOP) or a 600-mil plastic DIP, or a 8

× 20

mm TSOP with thickness of 1.2 mm, is available

for high density mounting. TSOP package is

suitable for cards, and reverse type TSOP is also

provided.

Features

• High speed

— Fast access time: 55/70/85/100 ns (max)

• Low power

— Active: 75 mW (typ)

— Standby: 10 µW (typ)

• Single 5 V supply

• Completely static memory

No clock or timing strobe required

• Equal access and cycle times

• Common data input and output

Three state output

• Directly TTL compatible

All inputs and outputs

• Capability of battery back up operation

2 chip selection for battery back up
