• Manufacturer Part Number: IDT7028
• Description: 64k X16 Dual-port Ram
• Manufacturer: Integrated Device Technology

Pin Configurations
Description
IDT7028 is designed to be used as a stand-alone 1024K-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 in 32-bit or wider memory system applications results in full-
speed, error-free operation without the need for additional discrete logic.
NOTES:
1. All Vcc pins must be connected to power supply.
2. All GND pins must be connected to ground.
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.

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 the chip enables (CE
circuitry of each port to enter a very low standby power mode.
devices typically operate on only 1W of power.
