DESCRIPTION

The EDI8F321024C is a high speed 32 megabit Static RAM module organized as 1024K words by 32 bits. This module is constructed from eight 1024Kx4 Static RAMs in SOJ packages on an epoxy laminate (FR4) board.

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.

The EDI8F321024C is offered in 72 pin ZIP and 72 lead SIMM packages, which enable 32 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.
