7026S/L
High-Speed 16K x 16 Dual-Port Static RAM
Description
The IDT7026 is a high-speed 16K x 16 Dual-Port Static RAM. The
IDT7026 is designed to be used as a stand-alone 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
Military, Industrial and Commercial Temperature Ranges
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.
The IDT7026 is packaged in a ceramic 84-pin PGA, and a 84-pin
PLCC. Military grade product is manufactured in compliance with MIL-
PRF-38535 QML, making it ideally suited to military temperature appli-
cations demanding the highest level of performance and reliability.
