2 / 18 page IDT70V18L High-Speed 3.3V 64K x 9 Dual-Port Static RAM Industrial and Commercial Temperature Ranges 2 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 forreadsorwritestoanylocationinmemory.Anautomaticpowerdown featurecontrolledbythe chipenables(eitherCE0orCE1)permittheon- 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 440mW of power. TheIDT70V18ispackagedina100-pinThinQuadFlatpack(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.
