256Kx32 SRAM Module

EDI8F32259C Rev. 1 12/97 ECO #9619
The EDI8F32259C is a high speed 8 megabit 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 (E-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 EDI8F32259C 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 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 four PD (Presence Detect)
pins which are used to identify module memory density in
applications where alternate modules can be interchanged.
