DESCRIPTION
1024Kx8 bit CMOS Static
Random Access Memory
•
•
•
•
Access Times 70 thru 100ns
Data Retention Function (EDI8F81024LP)
TTL Compatible Inputs and Outputs
Fully Static, No Clocks
High Density Packaging
• 36 Pin SIP, No. 62
Single +5V (±10%) Supply Operation
*This product is subject to change without notice.
The EDI8F81024C is a 8Mb CMOS Static RAM based on eight
128Kx8 Static RAMs mounted on a multi-layered epoxy laminate
(FR4) substrate.
A version featuring Low Power with Data Retention (EDI8F81024LP)
is also available.
The EDI8F81024C is offered in a double sided, 36 pin single-in-line
Package (SIP). Surface mount SIP technology is a cost effective
solution to very high packing density requirements.
All inputs and outputs are TTL compatible and operate from a single
5V supply. Fully asynchronous, the EDI8F81024C requires no clocks
or refreshing for operation.

*Stress greater than those listed under "Absolute Maximum Ratings" may
cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions greater
than those indicated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
