DEPTH EXPANSION CONFIGURATION (FWFT MODE ONLY)
The IDT72V36100 can easily be adapted to applications requiring depths
greaterthan65,536and131,072fortheIDT72V36110,withan36-bitbuswidth.
In FWFT mode, the FIFOs can be connected in series (the data outputs of one
FIFOconnectedtothedatainputsofthenext)withnoexternallogicnecessary.
The resulting configuration provides a total depth equivalent to the sum of the
depths associated with each single FIFO. Figure 30 shows a depth expansion
using two IDT72V36100/72V36110 devices.

in the depth expansion configuration. The first word written to an empty
configuration will pass from one FIFO to the next ("ripple down") until it finally
appears at the outputs of the last FIFO in the chain – no read operation is
necessarybuttheRCLKofeachFIFOmustbefree-running. Eachtimethedata
word appears at the outputs of one FIFO, that device's
OR line goes LOW,
enabling a write to the next FIFO in line.
For an empty expansion configuration, the amount of time it takes for
ORof
the last FIFO in the chain to go LOW (i.e. valid data to appear on the last FIFO's
outputs) after a word has been written to the first FIFO is the sum of the delays
for each individual FIFO:
(N – 1)*(4*transfer clock) + 3*TRCLK
whereNisthenumberofFIFOsintheexpansionandTRCLKistheRCLKperiod.
Note that extra cycles should be added for the possibility that the tSKEW1
specificationisnotmetbetweenWCLKandtransferclock,orRCLKandtransfer
clock, for the
OR flag.

depth expansion configuration. There will be no delay evident for subsequent
words written to the configuration.
The first free location created by reading from a full depth expansion
configurationwill"bubbleup"fromthelastFIFOtothepreviousoneuntilitfinally

FIFO in the chain to go LOW after a word has been read from the last FIFO is
the sum of the delays for each individual FIFO:
(N – 1)*(3*transfer clock) + 2 TWCLK
where N is the number of FIFOs in the expansion and TWCLK is the WCLK
period. NotethatextracyclesshouldbeaddedforthepossibilitythatthetSKEW1
