256Kx32 Static RAM CMOS, High Speed Module
DESCRIPTION
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.
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.
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.
All inputs and outputs are t
TL
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 P
D
(Presence Detect)
pins which are used to identify module memory density in
applications where alternate modules can be interchanged.
