IDT70P3519/99
High-Speed 1.8V 256/128K x 36 Dual-Port Synchronous Static RAM
Preliminary
Industrial and Commercial Temperature Ranges
Description:
The IDT70P3519/99 is a high-speed 256/128K x 36 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
IDT70P3519/99 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.
The 70P3519/99 can support an operating voltage of 3.3V, 2.5V or
1.8V on one or both ports. The power supply for the core of the device
(V
DD
) is 1.8V.
