DSC-4856/970V9389/289L High-Speed 3.3V 64K x18/x16 Dual-Port Synchronous Pipelined Static RAM Industrial & Commercial Temperature Ranges Description: The IDT70V9389/289 is a high-speed 64K x 18 (64K x 16) bit With an input data register, the IDT70V9389/289 has been synchronous Dual-Port RAM. The memory array utilizes Dual-Port optimized for applications having unidirectional or bidirectional data memory cells to allow simultaneous access of any address from both ports. flow in bursts. An automatic power down feature, controlled by CE0 Registers on control, data, and address inputs provide minimal setup and and CE1, permits the on-chip circuitry of each port to enter a very low hold times. The timing latitude provided by this approach allows systems standby power mode. Fabricated using CMOS high-performance to be designed with very short cycle times. technology, these devices typically operate on only 500mW of power.
