OPERATING MODES:
Care must be taken to assure that the appropriate flag is monitored by
eachsystem(i.e.FFismonitoredonthedevicewhereWisused;EFismonitored
onthedevicewhereR isused).Foradditionalinformation,refertoTechNote
8: Operating FIFOs on Full and Empty Boundary Conditions and Tech Note
6: Designing with FIFOs.
SINGLE DEVICE MODE
A single IDT7200/7201A/7202A may be used when the application
requirements are for 256/512/1,024 words or less. These devices are in a
Single Device Configuration when the Expansion In (XI) control input is
grounded (see Figure 12).
DEPTH EXPANSION
The IDT7200/7201A/7202A can easily be adapted to applications when
the requirements are for greater than 256/512/1,024 words. Figure 14
demonstrates Depth Expansion using three IDT7200/7201A/7202As. Any
depthcanbeattainedbyaddingadditionalIDT7200/7201A/7202As. These
FIFOs operate in the Depth Expansion mode when the following conditions
are met:
1. ThefirstdevicemustbedesignatedbygroundingtheFirstLoad(FL)control
input.
2. All other devices must have FL in 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.
all must be set to generate the correct composite FF or EF). See Figure
14.
