Description
The IDT70V18 is a high-speed 64K x 9 Dual-Port Static RAM. The
IDT70V18 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 system. 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 (either
CE0 or 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 440mW of power.
The IDT70V18 is packaged in a 100-pin Thin Quad Flatpack
(TQFP).
NOTES:
1. All Vcc pins must be connected to power supply.
2. All GND pins must be connected to ground.
3. Package body is approximately 14mm x 14mm x 1.4mm.
4. This package code is used to reference the package diagram.
5. This text does not indicate orientation of the actual part-marking.
