The IDT72V10081/72V11081/72V12081/72V13081/72V14081 devices are low-power First-In, First-Out (FIFO) memories with clocked read and write controls. These devices have a 256, 512, 1,024, 2,048 and 4,096 x 8-bit memory array, respectively. These FIFOs are applicable for a wide variety of data buffering needs such as graphics and interprocessor communication. These FIFOs have 8-bit input and output ports. The input port is controlled by a free-running clock (WCLK) and Write Enable pin (WEN). Data is written into the Multimedia FIFO on every rising clock edge when the Write Enable pin is asserted. The output port is controlled by another clock pin (RCLK) and Read Enable pin (REN). 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 (OE ) is provided on the read port for three-state control of the output. The Multimedia FIFOs have two fixed flags, Empty (EF) and Full (FF). These FIFOs are fabricated using IDT's submicron CMOS technology. |
