IDT7027S/L
High-Speed 32K x 16 Dual-Port Static RAM
Description
The IDT7027 is a high-speed 32K x 16 Dual-Port Static RAM,
designed to be used as a stand-alone 512K-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.
The 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 the chip enables ( CE 0 and CE 1 ) permits the on-chip

Industrial and Commercial Temperature Ranges
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. The IDT7027 is
packaged in a 100-pin Thin Quad Flatpack (TQFP) and a 108-pin ceramic
Pin Grid Array (PGA).
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.
