IDT7028L
High-Speed 64K x 16 Dual-Port Static RAM
Industrial and Commercial Temperature Ranges
Description
The IDT7028 is a high-speed 64K x 16 Dual-Port Static RAM. The
IDT7028 is designed to be used as a stand-alone 1024K-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 the chip enables (CE0and CE1) permit 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 1W of power.
The IDT7028 is packaged in a 100-pin Thin Quad Flatpack (TQFP).
