USAGE MODES:
Width Expansion
Wordwidthmaybeincreasedsimplybyconnectingthecorrespondinginput
controlsignalsofmultipledevices. Statusflags(EF,FFandHF)canbedetected
from any one device. Figure 13 demonstrates an 18-bit word width by using
twoIDT7203/7204/7205/7206/7207/7208s. Anywordwidthcanbeattained
by adding additional IDT7203/7204/7205/7206/7207/7208s (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
IDT7203/7204/7205/7206/7207/7208s as shown in Figure 16. Both Depth
Expansion and Width Expansion may be used in this mode.
Data Flow-Through
Twotypesofflow-throughmodesarepermitted,areadflow-throughand
write flow-through mode. For the read flow-through mode (Figure 17), the
FIFO permits a reading of a single word after writing one word of data into an
empty FIFO. The data is enabled on the bus in (tWEF + tA) ns after the rising
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.
Inthewriteflow-throughmode(Figure18),theFIFOpermitsthewritingof
asinglewordofdataimmediatelyafterreadingonewordofdatafromafullFIFO.
The R line causes the FF to be deasserted but the W line being LOW causes
ittobeassertedagaininanticipationofanewdataword.Ontherisingedgeof
W, the new word is loaded in the FIFO. The W line must be toggled when FF
isnotassertedtowritenewdataintheFIFOandtoincrementthewritepointer.
Compound Expansion
The two expansion techniques described above can be applied together
in a straightforward manner to achieve large FIFO arrays (see Figure 15).
NOTE:
1. Flag detection is accomplished by monitoring the FF, EF and HF signals on either (any) device used in the width expansion configuration.
Do not connect any output signals together.
