HM628128DI Series

1 M SRAM (128-kword × 8-bit)

ADE-203-999A (Z)

Preliminary

Rev. 0.1

Jul. 8, 1999

Description

The Hitachi HM628128DI Series is 1-Mbit static RAM organized 131,072-kword × 8-bit. HM628128DI

Series has realized higher density, higher performance and low power consumption by employing Hi-CMOS

process technology. The HM628128DI Series offers low power standby power dissipation; therefore, it is

suitable for battery backup systems. It has package variations of standard 32-pin plastic DIP, standard 32-pin

plastic SOP.

Features

•

Single 5 V supply: 5 V ± 10%

Access time: 70 ns (max)

Power dissipation

Active: 30 mW/MHz (typ)

Standby: 10 µW (typ)

•

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

Battery backup operation

2 chip selection for battery backup

Temperature range: –40 to +85°C

•

Preliminary: The specification of this device are subject to change without notice. Please contact your
