DESCRIPTION
The EDI8F32512C is a high speed 16 megabit Static RAM
module organized as 512K words by 32 bits. This module is
constructed from four 512Kx8 Static RAMs in SOJ pack ag es
on an epoxy laminate (FR4) board.
Four chip enables (EØ-E3) are used to in de pend ently
en able the four bytes. Reading or writing can be ex e cut ed on
individual bytes or any combination of multiple bytes through
proper use of selects.
The EDI8F32512C is offered in 72 pin ZIP and 72 lead SIMM
packages, which enable 16 mega bits of mem o ry to be placed
in less than 1.3 square inches of board space.
All inputs and outputs are TTL compatible and op er ate from
a single 5V supply. Fully asynchronous cir cuit ry re quires no
clocks or refreshing for operation and pro vides equal access
and cycle times for ease of use.
Pins PD1- PD4, are used to identify module memory density in
ap pli ca tions where alternate modules can be in ter changed.
