IDT70V9389/289L
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
synchronous Dual-Port RAM. The memory array utilizes Dual-Port
memory cells to allow simultaneous access of any address from both ports.
Registers on control, data, and address inputs provide minimal setup and
hold times. The timing latitude provided by this approach allows systems
to be designed with very short cycle times.
With an input data register, the IDT70V9389/289 has been optimized
for applications having unidirectional or bidirectional data flow in bursts. An
automatic power down feature, controlled by
CE
0
and CE
1,
permits 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 500mW of power.
