OPERATING MODES:
Care must be taken to assure that the appropriate flag is monitored by
eachsystem(i.e.
FFismonitoredonthedevicewhereWisused;EFismonitored
on the device where
R is used).
SINGLE DEVICE MODE
A single IDT7280/7281/7282/7283/7284/7285 may be used when the
application requirements are for 256/512/1,024/2,048/4,096/8,192 words 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 devices can easily be adapted to applications when the require-
ments are for greater than 256/512/1,024/2,048/4,096/8,192 words. Figure
14 demonstrates a four-FIFO Depth Expansion using two IDT7280/7281/
7282/7283/7284/7285s. Any depth can be attained by adding additional
IDT7280/7281/7282/7283/7284/7285s. These FIFOs operate in the Depth
Expansion mode when the following conditions are met:
1. ThefirstFIFOmustbedesignatedbygroundingtheFirstLoad(
FL)control
input.
2. All other FIFOs must have
FLin the HIGH state.
3. The Expansion Out (
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
FFor EF). See Figure 14.
