IDT7007S/L
HIGH-SPEED 32K x 8 DUAL-PORT STATIC RAM	MILITARY AND COMMERCIAL TEMPERATURE RANGES

DESCRIPTION:

The IDT7007 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 fullspeed, 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 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 750mW of power.

The IDT7007 is packaged in a 68-pin pin PGA, a 68-pin PLCC, and a 80-pin TQFP (thin plastic quad flatpack). Military grade product is manufactured in compliance with the latest revision of MIL-STD-883, Class B, making it ideally suited to military temperature applications demanding the highest level of performance and reliability.

2.VCC = 5V, TA = +25°C, and are not production tested. ICCDC = 120mA (Typ.)

3.At f = fMAX, address and control lines (except Output Enable) are cycling at the maximum frequency read cycle of 1 / tRC, and using “AC Test Conditions” of input levels of GND to 3V.

4.f = 0 means no address or control lines change.

5.Port "A" may be either left or right port. Port "B" is the opposite from port "A".
