CMOS,Module
The EDI8F8259C is a 2 megabit CMOS Static RAM
based on two high speed 256Kx4 Static RAMs mounted
on a multi-layered epoxy laminate (FR4) substrate.
The 32 pin DIP pinout adheres to the JEDEC standard for
thetwomegabitdevice,toensurecompatibilitywithfuture
monolithics.
All inputs and outputs are TTL compatible and operate
from a single 5V supply. Fully asynchronous, the
EDI8F8259C requires no clocks or refreshing for opera-
tion.
