EDI8G322048C

2048K x 32 Static RAM CMOS, High Speed Module

FEATURES

DESCRIPTION

2048K x 32 bit CMOS Static

Random Access Memory

The EDI8G322048C is a high speed 64 megabit Static RAM

module organized as 2048K words by 32 bits. This module is

constructed from sixteen 1024K x 4 Static RAMs in SOJ pack-

ages on an epoxy laminate (FR4) board.

Access Times: 20, 25, and 35ns

Individual Byte Selects

Four chip enables (EØ-E3) and the highest order address line are

used to independently enable the four bytes as well as the low

or high block of addressable memory space. Reading or writing

can be executed on individual bytes or any combination of

multiple bytes through proper use of selects.

Fully Static, No Clocks

TTL Compatible I/O

High Density Package

72 lead SIMM, No. 356 (Straight)

Common Data Inputs and Outputs

Single +5V (±10%) Supply Operation

The EDI8G322048C is offered in a 72 lead SIMM package, which

enables 64 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.
