6: Designing with FIFOs.
SINGLE DEVICE MODE
A single IDT72V01/72V02/72V03/72V04/72V05/72V06 may be used
when the application requirements are for 512/1,024/2,048/4,096/8,192/
16,384wordsorless.ThesedevicesareinaSingleDeviceConfigurationwhen
the Expansion In ( XI) control input is grounded (see Figure 12).
TheseFIFOscaneasilybeadaptedtoapplicationswhentherequirements
are for greater than 512/1,024/2,048/4,096/8,192/16,384 words. Figure 14
demonstratesDepthExpansionusingthreeIDT72V01/72V02/72V03/72V04/
72V05/72V06s. Any depth can be attained by adding additional IDT72V01/
72V02/72V03/72V04/72V05/72V06s. These devices operate in the Depth
Expansionmodewhenthefollowingconditionsaremet:
1. ThefirstdevicemustbedesignatedbygroundingtheFirstLoad(FL)control
input.
2. All other devices must have FLin the HIGH state.
3. TheExpansionOut(XO)pinofeachdevicemustbetiedtotheExpansion
In ( XI ) pin of the next device. See Figure 14.
4. ExternallogicisneededtogenerateacompositeFullFlag(FF)andEmpty
Flag ( EF). This requires the ORing of all EFs and ORing of all FFs (i.e.
allmustbesettogeneratethecorrectcompositeFForEF). SeeFigure14.
5. The Retransmit ( RT) function and Half-Full Flag ( HF) are not available
in the Depth Expansion Mode.

Modules.
USAGE MODES:
WIDTH EXPANSION
Wordwidthmaybeincreasedsimplybyconnectingthecorrespondinginput
controlsignalsofmultipledevices. Statusflags(EF,FFandHF)canbedetected
from any one device. Figure 13 demonstrates an 18-bit word width by using
twoIDT72V01/72V02/72V03/72V04/72V05/72V06s. Anywordwidthcanbe
attainedbyaddingadditionalIDT72V01/72V02/72V03/72V04/72V05/72V06s
(Figure 13).
BIDIRECTIONAL OPERATION
Applications which require data buffering between two systems (each
system capable of Read and Write operations) can be achieved by pairing
IDT72V01/72V02/72V03/72V04/72V05/72V06sasshowninFigure16.Both
Depth Expansion and Width Expansion may be used in this mode.
DATAFLOW-THROUGH
Twotypesofflow-throughmodesarepermitted,areadflow-throughand
writeflow-throughmode. Forthereadflow-throughmode(Figure17),theFIFO
permitsareadingofasinglewordafterwritingonewordofdataintoanempty
FIFO. The data is enabled on the bus in (tWEF + tA) ns after the rising edge of
W,calledthefirstwriteedge,anditremainsonthebusuntilthe Rlineisraised
fromLOW-to-HIGH,afterwhichthebuswouldgointoathree-statemodeafter
tRHZ ns. The EFline would have a pulse showing temporary deassertion and
then would be asserted.
Inthewriteflow-throughmode(Figure18),theFIFOpermitsthewritingof

The Rline causes the FFto be deasserted but the Wline being LOW causes
it to be asserted again in anticipation of a new data word. On the rising edge
ofW,thenewwordisloadedintheFIFO.TheWlinemustbetoggledwhenFF
