IDT7201L/7201LA/7202LA CMOS ASYNCHRONOUS FIFO
256 x 9, 512 x 9 and 1,024 x 9
USAGE MODES:
WIDTH EXPANSION
Word width may be increased simply by connecting the corresponding
inputcontrolsignalsofmultipledevices. Statusflags(EF,FFandHF)canbe
detectedfromanyonedevice. Figure13demonstratesan18-bitwordwidth
by using two IDT7200/7201A/7202As. Any word width can be attained by
adding additional IDT7200/7201A/7202As (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
IDT7200/7201A/7202As as shown in Figure 16. Both Depth Expansion and
Width Expansion may be used in this mode.
DATA FLOW-THROUGH
Two types of flow-through modes are permitted, a read flow-through
and write flow-through mode. For the read flow-through mode (Figure 17),
theFIFOpermitsareadingofasinglewordafterwritingonewordofdatainto
anemptyFIFO. Thedataisenabledonthebusin(tWEF+tA)nsaftertherising
edgeofW,calledthefirstwriteedge,anditremainsonthebusuntiltheRline
is raised from LOW-to-HIGH, after which the bus would go into a three-state
mode after tRHZ ns. The EF line would have a pulse showing temporary
deassertion and then would be asserted.
In the write flow-through mode (Figure 18), the FIFO permits the writing
of a single word of data immediately after reading one word of data from a
fullFIFO. TheRlinecausestheFFtobedeassertedbuttheWlinebeingLOW
causesittobeassertedagaininanticipationofanewdataword. Ontherising
edge of W, the new word is loaded in the FIFO. The W line must be toggled
whenFFisnotassertedtowritenewdataintheFIFOandtoincrementthewrite
pointer.
COMPOUND EXPANSION
The two expansion techniques described above can be applied together
in a straightforward manner to achieve large FIFO arrays (see Figure 15).
