524288-word × 8-bit High Speed CMOS Static RAM
ADE-203-236F (Z) Rev. 6.0 Jun. 9, 1995 Description
The Hitachi HM628512 is a 4-Mbit static RAM organized 512-kword × 8-bit. It realizes igher density, higher performance and low power consumption by employing 0.5 m Hi-CMOS process technology. The device, packaged in a 525-mil SOP (foot print pitch width) or 400-mil TSOP TYPE II or 600-mil plastic DIP, is available for high density mounting. LP-version is suitable for battery backup system.
