General Description

The IDT72V801/72V811/72V821/72V831/72V841/72V851/72V851 are dual synchronous (clocked) FIFOs. The device is functionally equivalent two IDT72V201/72V211/72V221/72V231/72V241/72V251 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 IDT72V80/72V811/72V821/ 72V831/ 72V841/72V851 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 (
