The device provides two independent ports with separate control, address,andI/Opinsthatpermit independent,asynchronousaccessfor reads or writes to any location in memory. An automatic power down featurecontrolledby thechipenables(CE0andCE1)permitstheon-chip circuitry of each port to enter a very low standby power mode. Fabricated using CMOS high-performance technology, these de- vices typically operate on only 750mW of power. The IDT7027 is packagedina100-pinThinQuadFlatpack(TQFP)anda108-pinceramic Pin Grid Array (PGA). Pin Configurations(1,2,3) NOTES: 1. All VCC pins must be connected to power supply. 2. All GND pins must be connected to ground supply. 3. Package body is approximately 14mm x 14mm x 1.4mm. 4. This package code is used to reference the package diagram. 5. This text does not indicate orientation of the actual part-marking.
