128KX32 STATIC RAM CMOS, HIGH SPEED MODULE

FEATURES

DESCRIPTION

The EDI8F32128C is a high speed 4Mb Static RAM

module organized as 128K words by 32 bits. This module is

constructed from four 128Kx8 Static RAMs in SOJ packages

on an epoxy laminate (FR4) board.

ꢀ

128Kx32 bit CMOS Static

Random Access Memory

ꢀ

Access Times: 15, 20, and 25ns

Individual Byte Selects

Fully Static, No Clocks

TTL Compatible I/O

Four chip enables (E0# - 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.

ꢀ

Single +5V ( 10ꢀ) Supply Operation

The EDI8F32128C is offered in 64 pin ZIP/SIMM package

which enables eight megabits of memory to be placed in

less than 1.4 square inches of board space.

High Density Package with JEDEC Standard

Pinouts

ꢀ

64 Pin ZIP, No. 85

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.

• Height: 13.97 (0.550")

64 Lead SIMM, No. 333

• Height: 15.62 (0.615")

Common Data Inputs and Outputs

The ZIP and SIMM modules contain two pins, PD1

and PD2, which are used to identify module memory

density in applications where alternate modules can be

interchanged.
