Description:
The IDT70T3339/19/99 is a high-speed 512/256/128k x 18 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
IDT70T3339/19/99 has been optimized for applications having unidirec-
tional or bidirectional data flow in bursts. An automatic power down feature,
controlled by CE0 and CE1, permits the on-chip circuitry of each port to
enter a very low standby power mode.
The IDT70T3339/19/99 can support an operating voltage of either
3.3V or 2.5V on one or both ports, controllable by the OPT pins. The power
supply for the core of the device (VDD) is at 2.5V.
