General Description
IDT70V24L General Description
The IDT70V24 is a high-speed 4K x 16 Dual-Port Static RAM. The DT70V24 is designed to be used as a stand-alone 64K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach n 32-bit or wider memory system applications results in full-speed, errorree 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, asyn-chronous access for reads or writes to any location in memory. An automatic power down feature controlled by CE permits 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 400mW of power.
The IDT70V24 is packaged in a ceramic 84-pin PGA, an 84-Pin PLCC and a 100-pin Thin Quad Flatpack.

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 in 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 Vcc +0.3V for more than 25% of the cycle time or 10ns maximum, and is limited to 20mA for the period over VTERM Vcc + 0.3V
