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.
