Single +5V (±10%) Supply Operation
The EDI9F37512C is a high speed 20 megabit Static
RAM module organized as 512K words x 37 bits. This
module is constructed from five 512Kx8 Static RAMs in
TSOP packages on an epoxy laminate (FR4) board.
Four write selects (W0-W3) are used to independently
enable the four bytes. Reading and writing can be
executed on individual bytes or any combination of
multiple bytes through proper use of selects.
The EDI9F37512C is offered in a 72 lead SIMM which
allows 20 megabits of memory to be placed in less than
1.5 square inch or board space.
All inputs and outputs are TTL compatible and operate
from a single 5V supply. Fully asynchronous circuitry
requires no clocks or refreshing for operation and pro-
vides equal access and cycle times for ease of use.
The SIMM module contains two Presence Detect pins
which are used to identify module memory density in
applications where alternate modules can be inter-
changed.
