DESCRIPTION
The EDI8F32128V is a high speed 4 megabit Static RAM module
organized as 128K words by 32 bits. This module is constructed
from four 128K x 8 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
enables.
The EDI8F32128V is offered in 64 pin ZIP and 64 Pad SIMM
packages, which enable four 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.
Two pins, PD1 and PD2, are used to identify module memory
density in applications where alternate modules can be inter-
changed.
