128KX32 STATIC RAM CMOS, HIGH SPEED MODULE
The EDI8F32128C is a high speed 4Mb Static RAM
module organized as 128K words by 32 bits. This module is
constructed from four 128Kx8 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 EDI8F32128C is offered in 64 pin ZIP/SIMM package
which enables eight megabits of memory to be placed in
less than 1.4 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.
The ZIP and SIMM modules contain two pins, PD1
and PD2, which are used to identify module memory
density in applications where alternate modules can be
interchanged.
