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, address, and I/O pins that permit independent, asyn-
chronous 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 technol-
ogy, 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 manu-
factured in compliance with the latest revision of MIL-STD-
883, 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
input.
