1Mx8 Static RAM CMOS, Module
FEATURES
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
EDI8F81024C
DESCRIPTION
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.
High Density Packaging * 36 Pin SIP, No. 62 Single +5V (10%) Supply Operation
*This product is subject to change without notice.
