EDI8F32512C
512Kx32 Static RAM CMOS, High Speed Module
FEATURES
DESCRIPTION
512Kx32 bit CMOS Static
Random Access Memory
www.DataSheet4U.com
Access Times: 15, 20, and 25ns
Individual Byte Selects
Fully Static, No Clocks
TTL Compatible I/O
High Density Package
72 Pin ZIP, No. 173
72 lead SIMM, No. 174 (Gold Option)
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 packages
on an epoxy laminate (FR4) board.
Four chip enables (EØ-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 EDI8F32512C is offered in 72 pin ZIP and 72 lead SIMM
packages, which enable 16 megabits of memory to be placed
in less than 1.3 square inches of board space.
Common Data Inputs and Outputs
Single +5V (±10%) Supply Operation
Note: Consult factory for availability of:
• RoHS compliant products
• Vendor source control options
• Industrial temperature option
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.
Pins PD1- PD4, are used to identify module memory density in
applications where alternate modules can be interchanged.
