Description:

The IDT709089 is a high-speed 64K x 8 bit synchronous Dual-Port

RAM. The memory array utilizes Dual-Port memory cells to allow

simultaneousaccessofanyaddressfrombothports.Registersoncontrol,

NOTES:

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.

With an input data register, the IDT709089 has been optimized for

applications having unidirectional or bidirectional data flow in bursts.

An automatic power down feature, controlled by

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 950mW of power.
