DESCRIPTION:
TheIDT72420/72200/72210/72220/72230/72240SyncFIFOarevery
high-speed,low-powerFirst-In,First-Out(FIFO)memorieswithclocked read
andwritecontrols.Thesedeviceshavea64,256,512,1,024,2,048,and4,096
x 8-bit memory array, respectively. These FIFOs are applicable for a wide
varietyofdatabufferingneeds,suchasgraphics,LocalAreaNetworks(LANs),
andinterprocessorcommunication.
TheseFIFOshave8-bitinputandoutputports.Theinputportiscontrolled
byafree-runningclock(WCLK),andaWriteEnablepin(WEN). Dataiswritten
intotheSynchronousFIFOoneveryclockwhenWENisasserted.Theoutput
port is controlled by another clock pin (RCLK) and a Read Enable pin (REN).
TheReadClockcanbetiedtotheWriteClockforsingleclockoperationorthe
twoclockscanrunasynchronousofoneanotherfordualclockoperation.An
Output Enable pin (OE) is provided on the read port for three-state control of
theoutput.
These Synchronous FIFOs have two endpoint flags, Empty (EF) and Full
(FF).Twopartialflags,Almost-Empty(AE)andAlmost-Full(AF),areprovided
forimprovedsystemcontrol.Thepartial(AE)flagsaresettoEmpty+7andFull-
7 for AE and AF respectively.
These FIFOs are fabricated using high-speed submicron CMOS technol-
ogy.
