HM62W8512BI Series

4 M SRAM (512-kword

8-bit)

ADE-203-1086A (Z)

Rev. 1.0

Jul. 13, 1999

Description

The Hitachi HM62W8512BI is a 4-Mbit static RAM organized 512-kword

8-bit. HM62W8512BI Series

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

technology. The HM62W8512BI Series offers low power standby power dissipation; therefore, it is suitable

for battery backup systems. It is packaged in standard 32-pin TSOP II.
