Integrated Device Technology 

IDT723622/723632/723642 CMOS SyncBiFIFO™

256 x 36 x 2, 512 x 36 x 2, 1,024 x 36 x 2

COMMERCIAL TEMPERATURE RANGE

DESCRIPTION (CONTINUED)

coincident. The enables for each port are arranged to provide a simple

bidirectional interface between microprocessors and/or buses with syn-

chronous control.

Each FIFO has a programmable Almost-Empty flag (AEA and AEB)

and a progammable Almost-Full flag (AFA and AFB). AEA and AEB

indicate when a selected number of words remain in the FIFO memory.

AFA and AFB indicate when the FIFO contains more than a selected

number of words.

The Input Ready (IRA, IRB) and Almost-Full (AFA, AFB) flags of a FIFO

are two-stage synchronized to the port clock that writes data into its array. The

Output Ready (ORA, ORB) and Almost-Empty (AEA, AEB) flags of a FIFO are

two-stage synchronized to the port clock that reads data from its array. Offset

values for the Almost-Full and Almost-Empty flags of both FIFOs can be

programmed from Port A.

Two or more devices may be used in parallel to create wider data paths.

If, at any time, the FIFO is not actively performing a function, the chip will

automatically power down. During the power down state, supply current

consumption (ICC) is at a minimum. Initiating any operation (by activating control

inputs will immediately take the device out of the power down state.

The 723622/723632/723642 are characterized for operation from

0°C to 70°C. They are fabricated using high speed, submicron CMOS

technology.
