The EDI8F321024C is a high speed 32 megabit Static RAM
module organized as 1024K words by 32 bits. This module
is constructed from eight 1024Kx4 Static RAMs in SOJ
packages on an epoxy laminate (FR4) board.
Four chip enables (EØ#-E3#) are used to independently
enable the four bytes. Reading or writing can be executed
on individual bytes or any combination of multiple bytes
through proper use of selects.
The EDI8F321024C is offered in 72 pin ZIP and 72 lead
SIMM packages, which enable 32 megabits of memory to
be placed in less than 1.3 square inches of board space.
All inputs and outputs are TTL compatible and operate from
a single 5V supply. Fully asynchronous circuitry requires
no clocks or refreshing for operation and provides equal
access and cycle times for ease of use.
Pins PD1- PD4, are used to identify module memory
density in applications where alternate modules can be
interchanged.
