Description
The Hitachi HM658512A is a CMOS pseudo static RAM organized 512-kword
density, higher performance and low power consumption by employing 0.8 µm 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. HM658512A 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 8
of 1.2 mm, or a 600-mil plastic DIP. High density custom cards made of Tape Carrier Packages are also
available.
