256Kx8 Static RAM
CMOS, Module
The EDI8F8257C is a two megabit CMOS Static RAM based on
two 128Kx8 Static RAMs mounted on a multi-layered epoxy
laminate (FR4) substrate.
Functional equivalence to the monolithic two megabit Static RAM
is achieved by utilization of an on-board decoder that interprets the
higher order address (A17) to select one of the 128Kx8 Static
RAMs.
The 32 pin DIP pinout adheres to the JEDEC standard for the two
megabit device, to ensure compatibility with future monolithics.
The device is available with Low Power and Data Retention
(EDI8F8257LP).
All inputs and outputs are TTL compatible and operate from a
single 5V supply. Fully asynchronous, the EDI8F8257C requires
no clocks or refreshing for operation.
