OPERATING MODES:
Care must be taken to assure that the appropriate flag is monitored by
eachsystem(i.e.FFismonitoredonthedevicewhereWisused;EFismonitored
onthedevicewhereRisused).ForadditionalinformationontheIDT7203/7204/
7205/7206/7207, refer to Tech Note 8: Operating FIFOs on Full and Empty
Boundary Conditions and Tech Note 6: Designing with FIFOs.
Single Device Mode
A single IDT7203/7204/7205/7206/7207/7208 may be used when the
applicationrequirementsarefor2,048/4,096/8,192/16,384/32,768/65,536words
or less. These FIFOs are in a Single Device Configuration when the Expansion
In (XI) control input is grounded (see Figure 12).
Depth Expansion
These FIFOs can easily be adapted to applications when the require-
mentsareforgreaterthan2,048/4,096/8,192/16,384/32,768/65,536words.
Figure 14 demonstrates Depth Expansion using three IDT7203/7204/7205/
7206/7207/7208s. AnydepthcanbeattainedbyaddingadditionalIDT7203/
7204/7205/7206/7207/7208s. ThesedevicesoperateintheDepthExpansion

2. All other devices must have FLin the HIGH state.
3. TheExpansionOut(XO)pinofeachdevicemustbetiedtotheExpansion

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 FFor EF). See Figure 14.
5. The Retransmit (RT) function and Half-Full Flag (HF) are not available in
the Depth Expansion Mode.
