FEATURES
DESCRIPTION
The EDI8F81024C is a 8Mb CMOS Static RAM based on eight
128Kx8 Static RAMs mounted on a multi-layered epoxy laminate
(FR4) substrate.
A version featuring Low Power with Data Retention (EDI8F81024LP)
is also available.
The EDI8F81024C is offered in a double sided, 36 pin single-in-line
Package (SIP). Surface mount SIP technology is a cost effective
solution to very high packing density requirements.
All inputs and outputs are TTL compatible and operate from a single
5V supply. Fully asynchronous, the EDI8F81024C requires no clocks
or refreshing for operation.
