High-Speed 2K x 16 Dual-Port RAM
Military, Industrial and Commercial Temperature Ranges
Description
The IDT7133/7143 are high-speed 2K x 16 Dual-Port Static RAMs.
The IDT7133 is designed to be used as a stand-alone 16-bit Dual-Port
RAM or as a “MASTER” Dual-Port RAM together with the IDT7143
“SLAVE” Dual-Port in 32-bit-or-more word width systems. Using the IDT
MASTER/SLAVE Dual-Port RAM approach in 32-bit-or-wider memory
system applications results in full-speed, error-free operation without the
need for additional discrete logic.
Both devices provide two independent ports with separate control,
Pin Configurations
(1,2,3)
INDEX
address, and I/O pins that permit independent, asynchronous access for
reads or writes to any location in memory. An automatic power down
feature, controlled by
CE,
permits the on-chip circuitry of each port to enter
a very low standby power mode.
Fabricated using CMOS high-performance technology. Low-power
(LA) versions offer battery backup data retention capability, with each port
typically consuming 200µW for a 2V battery.
The IDT7133/7143 devices have identical pinouts. Each is packed in
a 68-pin ceramic PGA, 68-pin flatpack, 68-pin PLCC and 100-pin TQFP.
Military grade product is manufactured in compliance with the latest revision
of MIL-PRF-38535 QML, making it ideally suited to military temperature
applications demanding the highest level of performance and reliability.

NOTES:
1. V
CC
= 5V, T
A
= +25°C for Typ., and are not production tested. I
CCDC
= 180mA (typ.)
2. 'X' in part number indicates power rating (SA or LA)
3. At f = f
MAX
,
address and control lines (except Output Enable) are cycling at the maximum frequency read cycle of 1/ t
RC,
and using “AC Test Conditions" of input levels of
GND to 3V.
4. f = 0 means no address or control lines change. Applies only to inputs at CMOS level standby.
5. Port "A" may be either left or right port. Port "B" is the opposite from port "A".
