Description
The Hitachi HM65W8512 is a CMOS pseudo static RAM organized 512-kword
×
8bit. It realizes higher
density, higher performance and low power consumption by employing 0.8
μ
m Hi-CMOS process
technology.
It offers low power data retention by self refresh mode. It also offers easy non multiplexed address
interface and easy refresh functions. HM65W8512 is suitable for handy systems which work with battery
back-up systems.
The device is packaged in a small 525-mil SOP (460-mil body SOP) or a 400 mil TSOP TYPE II.
