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 (E-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.
