EDI8F32259V

256Kx32 Static RAM CMOS, High Speed Module

FEATURES

DESCRIPTION

256Kx32 bit CMOS Static RAM

Access Times: 12, 15, 20, and 25ns

Individual Byte Selects

The EDI8F32259V is a high speed 8Mb Static RAM module

organized as 256K words by 32 bits. This module is constructed

from eight 256Kx4 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

selects.

TTL Compatible I/O

High Density Package with JEDEC Standard Pinouts

72 Pin SIMM No. 175 (Angle)

72 Pin ZIP No. 176

The EDI8F32259V is offered in 72 pin ZIP/SIMM package which

enables eight megabits of memory to be placed in less than 1.3

square inches of board space.

72 Pin SIMM, No. 354 (Straight)

Single +3.3V (±10%) Supply Operation

All inputs and outputs are TTL compatible and operate from a

single 3.3V supply. Fully asynchronous circuitry requires no

clocks or refreshing for operation and provides equal access and

cycle times for ease of use.

The ZIP and SIMM modules contain four PD (Presence Detect)

pins which are used to identify module memory density in appli-

cations where alternate modules can be interchanged.
