IDT70V3579S

High-Speed 32K x 36 Dual-Port Synchronous Pipelined Static RAM

Industrial and Commercial Temperature Ranges

Description:

The IDT70V3579 is a high-speed 32K 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

IDT70V3579 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 70V3579 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 (V

DD

) remains at 3.3V.

pins must be connected to 3.3V power supply.

2. All V

DDQ

pins must be connected to appropriate power supply: 3.3V if OPT pin for that port is set to V

IH

(3.3V), and 2.5V if OPT pin for that port is set to V

IL

(0V).

3. All V

SS

pins must be connected to ground supply.

NOTES:

1. V

DD

, OPT

X

, and V

DDQX

must be set to appropriate operating levels prior to

applying inputs on the I/Os and controls for that port.

2. OPT

X

selects the operating voltage levels on that port. If OPT

X

is set to VIH (3.3V),

then that port's I/Os and controls will operate at 3.3V levels and V

DDQX

must be

supplied at 3.3V. If OPT

X

is set to VIL (0V), then that port's I/Os and controls will

operate at 2.5V levels and V

DDQX

must be supplied at 2.5V. The OPT pins are

independent of one another—both ports can operate at 3.3V levels, both can

operate at 2.5V levels, or either can operate at 3.3V with the other at 2.5V.
