DESCRIPTION
The EDI8F8512C is a 4096K bit CMOS Static RAM based on four
128Kx8 or 256Kx4 (high speed) Static RAMs mounted on a multi-
layered epoxy laminate (FR4) substrate.
Functional equivalence to the monolithic four megabit Static RAM
is achieved by utilization of an on-board decoder that interprets the
higher order address(es) to select one of the128Kx8 or 256Kx4 Static
RAMs.
The 32 pin DIP pinout adheres to the JEDEC standard for the four
megabit device, to ensure compatibility with future monolithics.
A low power version with data retention (EDI8F8512LP) is also
available.
All inputs and outputs are TTL compatible and operate from a single
5V supply. Fully asynchronous, the EDI8F8512C requires no clocks
or refreshing for operation.
