DESCRIPTION:

The IDT72801/72811/72821/72831/72841/72851 are dual synchronous

(clocked) FIFOs. The device is functionally equivalent to two IDT72201/72211/

72221/72231/72241/72251 FIFOs in a single package with all associated

control, data, and flag lines assigned to separate pins.

Each of the two FIFOs (designated FIFO A and FIFO B) contained in the

IDT72801/72811/72821/72831/72841/72851 has a 9-bit input data port (DA0

- DA8, DB0 - DB8) and a 9-bit output data port (QA0 - QA8, QB0 - QB8). Each

input port is controlled by a free-running clock (WCLKA, WCLKB), and two Write

Enable pins (WENA1, WENA2,

WENB1,

WENB2). Data is written into each of

the two arrays on every rising clock edge of the Write Clock (WCLKA, WCLKB)

when the appropriate write enable pins are asserted.

The output port of each FIFO bank is controlled by its associated clock pin

(RCLKA, RCLKB) and two Read Enable pins (RENA1,

RENA2, RENB1,

RENB2).

The Read Clock can be tied to the Write Clock for single clock operation

or the two clocks can run asynchronous of one another for dual clock operation.

An Output Enable pin (OEA,

OEB)

is provided on the read port of each FIFO

for three-state output control.

Each of the two FIFOs has two fixed flags, Empty (EFA,

EFB)

and Full (FFA,

FFB).

Two programmable flags, Almost-Empty (PAEA,

PAEB)

and Almost-Full

(PAFA,

PAFB),

are provided for each FIFO bank to improve memory utilization.

If not programmed, the programmable flags default to empty+7 for

PAEA

and

PAEB,

and full-7 for

PAFA

and

PAFB.

The IDT72801/72811/72821/72831/72841/72851 architecture lends itself

to many flexible configurations such as:

• 2-level priority data buffering

• Bidirectional operation

• Width expansion

• Depth expansion

These FIFOs is fabricated using high-performance submicron CMOS

technology.
