IDT7005S/L
High-Speed 8K x 8 Dual-Port Static RAM
Military, Industrial and Commercial Temperature Ranges
Description
The IDT7005 is a high-speed 8K x 8 Dual-Port Static RAM. The
IDT7005 is designed to be used as a stand-alone 64K-bit Dual-Port RAM
or as a combination MASTER/SLAVE Dual-Port RAM for 16-bit-or-
more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM
approach in 16-bit or wider memory system applications results in full-
speed, error-free operation without the need for additional discrete logic.
This device provides 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 CMOS high-performance technology, these de-
vices typically operate on only 750mW of power. Low-power (L) versions
offer battery backup data retention capability with typical power consump-
tion of 500µW from a 2V battery.
The IDT7005 is packaged in a ceramic 68-pin PGA, 68-pin PLCC
and a 64-pin thin quad flatpack, (TQFP). Military grade product is
manufactured in compliance with MIL-PRF-38535 QML making it ideally
suited to military temperature applications demanding the highest level of
performance and reliability.
