IDT7024S/L
High-Speed 4K x 16 Dual-Port Static RAM
Military, Industrial and Commercial Temperature Ranges
Description
The IDT7024 is a high-speed 4Kx 16 Dual-Port Static RAM. The
IDT7024 is designed to be used as a stand-alone 64K-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 IDT7024 is packaged in a ceramic 84-pin PGA, an 84-pin Flatpack
and PLCC, and a 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.
