HM62W16256B Series

4 M SRAM (256-kword × 16-bit)

ADE-203-934C (Z)

Rev. 2.0

Oct. 14, 1999

Description

The Hitachi HM62W16256B Series is 4-Mbit static RAM organized 262,144-word × 16-bit. HM62W16256B

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

process technology. It offers low power standby power dissipation; therefore, it is suitable for battery backup

systems. It is packaged in standard 44-pin plastic TSOPII.
