EDI8F32128V

128K x 32 Static RAM CMOS, High Speed Module

DESCRIPTION

FEATURES

128K x 32 bit CMOS Static RAM

Access Times: 10 and 12ns

Individual Byte Selects

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.

Fully Static, No Clocks

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.

TTL Compatible I/O

High Density Package

JEDEC Standard Pinouts

64 Pad SIMM, No. 38

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.

64 Pin ZIP, No. 39

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.

Common Data Inputs and Outputs

Single +3.3V (±10%) Supply Operation

Two pins, PD1 and PD2, are used to identify module memory

density in applications where alternate modules can be inter-

changed.
