These devices have a 64, 256, 512, 1,024, 2,048,4,096,and8,192x9-bitmemoryarray,respectively. TheseFIFOsare applicableforawidevarietyofdatabufferingneedssuchasgraphics,localarea networksandinterprocessorcommunication. TheseFIFOshave9-bitinputandoutputports.Theinputportiscontrolled by a free-running clock (WCLK), and two write enable pins (WEN1, WEN2). Data is written into the Synchronous FIFO on every rising clock edge when thewriteenablepinsareasserted.Theoutputportiscontrolledbyanotherclock pin (RCLK) and two read enable pins (REN1, REN2). 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 Synchronous FIFOs have two fixed flags, Empty (EF) and Full (FF). Two programmable flags, Almost-Empty (PAE) and Almost-Full (PAF), are provided for improved system control. The programmable flags default to Empty+7 and Full-7 for PAE and PAF, respectively. The programmable flag offsetloadingiscontrolledbyasimplestatemachineandisinitiatedbyasserting the load pin (LD). TheseFIFOsarefabricatedusinghigh-speedsubmicronCMOStechnology. |
