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 sec-tions of this specification is not implied. Exposure to absolute maxi-mum rating conditions for extended periods may affect reliability.
2. VTERM must not exceed Vcc + 10% for more than 25% of the cycle time or 10ns maximum, and is limited to 20mA for the period of VTERM Vcc + 10%.


Description

The IDT7007L is a high-speed 32K x 8 Dual-Port Static RAM. The IDT7007 is designed to be used as a stand-alone 256K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 16-bit-or-more word systems. Using the IDT MASTER/SLAVE Dual-Port RAM approach in 16-bit or wider memory system applications results in full-speed, errorfree operation without the need for additional discrete logic.

This IDT7007L 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 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 850mW of power. 

The IDT7007L is packaged in a 68-pin pin PGA, a 68-pin PLCC, and an 80-pin thin quad flatpack, TQFP. Military grade product is manufactured in compliance with the latest revision of MIL-PRF-38535 QML, Class B, making it ideally suited to military temperature applications demanding the highest level of performance and reliability.
