HM628128D Series

1 M SRAM (128-kword × 8-bit)

ADE-203-996 (Z)

Preliminary, Rev. 0.0

Jan. 20, 1999

Description

The Hitachi HM628128D Series is 1-Mbit static RAM organized 131,072-kword × 8-bit. HM628128D

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

CMOS process technology. The HM628128D 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 and standard 32-pin plastic TSOPI.
