1Mx8 CMOS SRAM MONOLITHIC
DESCRIPTION
FEATURES
The EDI8F81027C is an 8Mb CMOS Static RAM based on two
512Kx8 Static RAMs mounted on a multi-layered epoxy laminate
(FR4) substrate.
n 1 Mx8 bit CMOS Static RAM
• Access Times 55 through 100ns
• Data Retention Function (EDI8F81027LP )
• TTL Compatible Inputs and Outputs
• Fully Static, No Clocks
A low power version with data retention (EDI8F81027LP) is also
available.
All inputs and outputs are TTL compatible and operate from a
single 5V supply.
n High Density Packaging
Fully asynchronous, the EDI8F81027C requires no clocks or
refreshing for operation.
• 32 Pin DIP, No. 352
n Single +5V (±10%) Supply Operation
*This product is subject to change without notice.

*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.
