Description
The Hitachi HM62V8512C is a 4-Mbit static RAM organized 512-kword
×
8-bit. It realizes higher density,
higher performance and low power consumption by employing CMOS process technology (6-transistor
memory cell). The device, packaged in a 525-mil SOP (foot print pitch width) or 400-mil TSOP TYPE II is
available for high density mounting. The HM62V8512C is suitable for battery backup system.
