512Kx32 Static RAM CMOS, High Speed Module

FEATURES

DESCRIPTION

ꢀ

512Kx32 bit CMOS Static

Random Access Memory

The EDI8F32512C is a high speed 16 megabit Static RAM

module organized as 512K words by 32 bits. This module is

constructed from four 512Kx8 Static RAMs in SOJ packages

on an epoxy laminate (FR4) board.

ꢀ

Access Times: 15, 20, and 25ns

Individual Byte Selects

Fully Static, No Clocks

TTL Compatible I/O

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.

ꢀ

High Density Package

The EDI8F32512C is offered in 72 pin ZIP and 72 lead SIMM

packages, which enable 16 megabits of memory to be placed

in less than 1.3 square inches of board space.

ꢀ

72 Pin ZIP, No. 173

72 lead SIMM, No. 174 (Gold Option)

Common Data Inputs and Outputs

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.

Single +5V ( 10ꢀ) Supply Operation

Note: Consult factory for availability of:

• RoHS compliant products

Pins PD1- PD4, are used to identify module memory density in

applications where alternate modules can be interchanged.

• Vendor source control options

• Industrial temperature option
