NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2. VTERM must not exceed VDD + 0.3V for more than 25% of the cycle time or 10ns maximum, and is limited to < 20mA for the period of VTERM > VDD + 0.3V. 5643 tbl
The IDT70V17L is a high-speed 32K x 9 Dual-Port Static RAM. The IDT70V17L is designed to be used as a stand-alone 288K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 18-bitor- more word system. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 18-bit or wider memory system applications results in fullspeed, error-free operation without the need for additional discrete logic.
This IDT70V17L 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, the IDT70V17L typically operate on only 440mW of power. The IDT70V17L is packaged in a 100-pin Thin Quad Flatpack (TQFP).
