The EDI8F32512V is a high speed 16 Mb 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.
Four chip enables (E0#-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.

Common Data Inputs and Outputs
The EDI8F32512V is offered in 72 pin ZIP and 72 lead SIMM
packages, which enable 16 Mb 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 3.3V supply. Fully asynchronous circuitry requires no
clocks or refreshing for operation and provides equal access
and cycle times for ease of use.
Single +3.3V (±10%) Supply Operation
Pins PD0- PD3, are used to identify module memory density in
applications where alternate modules can be interchanged.
* This product is subject to change without notice.
