2 / 22 page Commercial and Industrial Temperature Range IDT 70V27S/L High-Speed 3.3V 32K x 16 Dual-Port Static RAM 2 Description: The IDT70V27 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 and wider word systems.UsingtheIDTMASTER/SLAVEDual-PortRAMapproachin32- 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 (CE0 and CE1) permits the on-chip circuitry of each port to enter a very low standby power mode. Fabricated using IDT’s CMOS high-performance technology, thesedevicestypicallyoperateononly500mWofpower. TheIDT70V27 is packaged in a 100-pin Thin Quad Flatpack (TQFP), a 108-pin ceramic Pin Grid Array (PGA), and a 144-pin Fine Pitch BGA (fp BGA). Pin Configurations(1,2,3) NOTES: 1. All VCC pins must be connected to power supply. 2. All GND pins must be connected to ground supply. 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.
