HM62256B Series

256k SRAM (32-kword × 8-bit)

ADE-203-135F (Z)

Rev. 6.0

Nov. 13, 1997

Description

The Hitachi HM62256B Series is a CMOS static RAM organized 32,768-word × 8-bit. It realizes higher

performance and low power consumption by employing 0.8 µm Hi-CMOS process technology. The

device, packaged in 8 × 14 mm TSOP, 8 × 13.4 mm TSOP with thickness of 1.2 mm, 450 mil SOP (foot

print pitch width), 600 mil plastic DIP, or 300 mil plastic DIP, is available for high density mounting. It

offers low power standby power dissipation; therefore, it is suitable for battery backup systems.

Features

•

Single 5.0 V supply: 5.0 V ± 10%

Access time: 55 ns/70 ns/85 ns (max)

Power dissipation:

Active: 25 mW (typ) (f = 1 MHz)

Standby: 1.0 µW (typ)

•

Completely static memory

No clock or timing strobe required

Equal access and cycle times

Common data input and output
