7133SA/LA, 7143SA/LA
High-Speed 2K x 16 Dual-Port RAM
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)
Military, Industrial and Commercial Temperature Ranges
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.
