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-or­more 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, 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 IDT’s CMOS high-performance technol­ogy, these devices typically operate on only 500mW of power.
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
packaged in a 68-pin ceramic PGA, a 68-pin flatpack, a 68-pin
PLCC, and a 100-pin TQFP. Military grade product is manu­factured in compliance with the latest revision of MIL-STD­883, Class B, making it ideally suited to military temperature
applications demanding the highest level of performance and
reliability.

1. IDT7133 (MASTER): BUSY is
open drain output and requires
pull-up resistor of 270Ω.
IDT7143 (SLAVE): BUSY is

1. Commercial only, 0°C to +70°C temperature range.

2. V

CC = 5V, TA = +25°C for Typ., and are not production tested. ICCDC = 180mA (Typ.)

3. "X" in part numbers indicates power rating (SA or LA).

4. At f = f

5. f = 0 means no address or control lines change. Applies only to inputs at CMOS level standby.

6. Port "A" may be either left or right port. Port "B" is the opposite from port "A".

MAX, address and control lines (except Output Enable) are cycling at the maximum frequency read cycle of 1 / tRC, and using “AC Test Conditions”

of input levels of GND to 3V.
