Description
The IDT7MP4036 is a 64K x 32 Static RAM module constructed on
an epoxy laminate (FR-4) substrate using eight 64K x 4 Static RAMs in
plastic SOJ packages. Availability of four chip select lines (one for each
group of two RAMs) provides byte access. Extremely fast speeds can be
achieved due to the use of 256K Static RAMs fabricated in IDT’s high-
performance, high-reliability CMOS technology. The IDT7MP4036 is
available with access time as fast as 12ns with minimal power consumption.
The IDT7MP4036 is packaged in a 64-pin FR-4 ZIP (Zig-zag In-line
vertical Package)or a 64-pin SIMM (Single In-line Memory Module). The
ZIP configuration allows 64 pins to be placed on a package 3.65 inches
long and 0.35 inches wide. At only 0.50 inches high, this low-profile
package is ideal for systems with minimum board spacing, while the SIMM
configuration allows use of edge mounted sockets to secure the module.
All inputs and outputs of the IDT7MP4036 are TTL-compatible and
operate from a single 5V supply. Full asynchronous circuitry requires no
clocks or refresh for operation and provides equal access and cycle times
for ease of use.
Two identification pins (PD
0
and PD
1
) are provided for applications in
which different density versions of the module are used. In this way, the
target system can read the respective levels of PD
0
and PD
1
to determine
a 64K depth.

NOTE:
1. Pins 2 and 3 (PD
0
and PD
1
) are read by the user to determine the density of
the module. If PD
0
reads Open and PD
1
reads GND, then the module had a
64K depth.
