IDT7006S/L
High-Speed 16K x 8 Dual-Port Static RAM
Military, Industrial and Commercial Temperature Ranges
Description
The IDT7006 is a high-speed 16K x 8 Dual-Port Static RAM. The
IDT7006 is designed to be used as a stand-alone 128K-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 IDT’s CMOS high-performance technology, these
devices typically operate on only 750mW of power. Low-power (L)
versions offer battery backup data retention capability with typical power
consumption of 500µW from a 2V battery.
The IDT7006 is packaged in a ceramic 68-pin PGA, an 68-pin quad
flatpack, a PLCC, and a 64-pin thin quad flatpack, TQFP. Military grade
product is manufactured in compliance with the latest revision of MIL-PRF-
38535 QML, Class B, making it ideally suited to military temperature
applications demanding the highest level of performance and reliability.
