EDI8F82049C
FEATURES
2 M x 8 bit CMOS Static
Random Access Memory
Access Times 70 thru 100ns
Data Retention Function (EDI8F82049LP )
TTL Compatible Inputs and Outputs
Fully Static, No Clocks
High Density Packaging
36 Pin SIP, No. 136
Single +5V (10%) Supply Operation
DESCRIPTION
The EDI8F82049C is a 16Mb CMOS Static RAM based on four
512K x 8 Static RAMs mounted on a multi-layered epoxy laminate
(FR4) substrate.
A low power version with data retention (EDI8F82049LP) is also
available.
The EDI8F82049C is offered in a 36 pin single-in-line package
(SIP), which provides a cost effective solution to very high packing
density.
All inputs and outputs are TTL compatible and operate from a
single 5V supply.
Fully asynchronous, the EDI8F82049C requires no clocks or
refreshing for operation.
