FUNCTIONAL DESCRIPTION:
TheIDT72413,65x5FIFOisdesignedusingadual-portRAMarchitecture
asopposedtothetraditionalshiftregisterapproach. ThisFIFOarchitecturehas
awritepointer,areadpointerandcontrollogic,whichallowsimultaneousread
andwriteoperations.Thewritepointerisincrementedbythefallingedgeofthe
ShiftIn(Sl)control;thereadpointerisincrementedbythefallingedgeoftheShift
Out (SO). The Input Ready (IR) signals when the FIFO has an available
memory location; Output Ready (OR) signals when there is valid data on the
output. OutputEnable(OE)providesthecapabilityofthree-statingtheFIFO
outputs.
FIFO RESET
TheFIFOmustberesetuponpowerupusingtheMasterReset(MR)signal.
ThiscausestheFIFOtoenteranemptystatesignifiedbyOutputReady(OR)
being LOW and Input Ready (IR) being HIGH. In this state, the data outputs
(Q0-4) will be LOW.
DATAINPUT
DataisshiftedinontheLOW-to-HIGHtransitionofShiftIn(Sl). Thisloads
input data into the first word location of the FIFO and causes the lnput Ready
(IR)togoLOW. OntheHlGH-to-LOWtransitionofSI,thewritepointerismoved
tothenextwordpositionand lRgoesHlGHindicatingthereadinesstoaccept
new data. If the FIFO is full, IR will remain LOW until a word of data is shifted
out.
DATAOUTPUT
DataisshiftedoutontheHIGH-to-LOWtransitionofShiftOut(SO).Thiscauses
the internal read pointer to be advanced to the next word location. If data is
present, valid data will appear on the outputs and Output Ready (OR) will go
HIGH.Ifdataisnotpresent,ORwillstayLOWindicatingtheFIFOisempty. The
lastvalidwordreadfromtheFIFOwillremainattheFlFOsoutputwhenitisempty.

SO.
FALL-THROUGHMODE
The FIFO operates in a Fall-Through Mode when data gets shifted into an
emptyFIFO.Afterthefall-throughdelaythedatapropagatestotheoutput.When
the data reaches the output, the Output Ready (OR) goes HIGH.
AFall-ThroughModealsooccurswhentheFIFOis completelyfull. When
dataisshiftedoutofthefullFIFOalocationisavailablefornewdata. Afterafall-
through delay, the lnput Ready goes HlGH. If Shift In is HIGH, the new data
canbewrittentotheFIFO. Thefall-throughdelayofaRAM-basedFIFO(one
clock cycle) is far less than the delay of a Shift register-based FIFO.
