IDT7018L
High-Speed 64K x 9 Dual-Port Static RAM
Industrial and Commercial Temperature Ranges
Description
The IDT7018 is a high-speed 64K x 9 Dual-Port Static RAM. The
IDT7018 is designed to be used as a stand-alone 576K-bit Dual-Port RAM
or as a combination MASTER/SLAVE Dual-Port RAM for 18-bit-or-more
word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach
in 18-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 (CE0 and CE1) permit 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 1W of power.
The IDT7018 is packaged in a 100-pin Thin Quad Flatpack (TQFP).
