2x512Kx8 Static RAM
CMOS, Module
The EDI9F81025C is an 8 megabit CMOS Static RAM based on
two 512Kx8 Static RAMs mounted on a multi-layered epoxy
laminate (FR4) substrate.
The EDI9F81025C is organized as two separate banks of 512Kx8
Random Access Memory, with common address and data pins to
minimize module size. It is offered with access times of 70, 85, and
100ns.
It is also available as EDI9F81025LP, which features Low Power
and Battery Back-up Data Retention.
All inputs and outputs are TTL compatible and operate from a
single 5V supply. Fully asynchronous, the EDI9F81025C requires
no clocks or refreshing for operation.
