Description
The IDT7025 is a high-speed 8K x 16 Dual-Port Static RAM. The
IDT7025 is designed to be used as a stand-alone 128K-bit Dual-Port RAM
or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit or more
word 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.
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 Chip Enable (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 IDT7025 is packaged in a ceramic 84-pin PGA, an 84-pin
Flatpack, PLCC, and a 100-pin TQFP. Military grade product is manu-
factured 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.
