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 technol- ogy, these devices typically operate on only 750mW of power. The IDT7015 is packaged in a ceramic 68-pin PGA, a 64- pin PLCC and an 80-pin TQFP (Thin 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. PIN CONFIGURATIONS (1,2) NOTES: 1. All VCC pins must be connected to power supply. 2. All GND pins must be connected to ground supply. 3. This text does not imply orientation of Part-Mark.
