Pin Configurations and Block Diagram
The EDI8F32128C is a high speed 4 megabit Static RAM
module organized as 128K words by 32 bits. This module is
constructed from four 128Kx8 Static RAMs in SOJ or TSOP
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 enables.
The EDI8F32128C is offered in 64 pin ZIP, 64 Pad SIMM
and 68 Lead PLCC packages, which enable four 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.
Two pins, PD1 and PD2, are used to identify module
memory density in applications where alternate modules
can be interchanged. (Zip and SIMM only) A low power
version with 2 volt data retention functionality is also avail-
able (PLCC package only.)
