32Kx32 Static RAM
CMOS, High Speed Module
The EDI8F3232C is a high speed megabit Static RAM
module organized as 32Kx32. This module is constructed
from four 32Kx8 Static RAMs in SOJ packages on an epoxy
laminate (FR4) board.
Four chip enables (E-E3) are used to independently
enable the four bytes. Reading or writing can be executed
on individual bytes or any combination of multiple bytes
through proper use of selects.
The EDI8F3232C is offered in both 64 lead SIMM and 64
pin ZIP packages, which enables one megabit of memory
to be placed in less than 1.2 square inches of board space.
All inputs and outputs are TTL compatible and operate from
a single 5V supply. Fully asynchronous circuitry is used,
requiring no clocks or refreshing for operation and providing
equal access and cycle times for ease of use.
