Description
The Hitachi HM62V8128D Series is 1-Mbit static RAM organized 131,072-kword
×
8-bit. HM62V8128D
Series has realized higher density, higher performance and low power consumption by employing Hi-
CMOS process technology. The HM62V8128D Series offers low power standby power dissipation;
therefore, it is suitable for battery backup systems. It has package variations of standard 32-pin plastic
SOP and standard 32-pin plastic TSOPI.
