memory is full or not. The IR and OR functions are selected in the First Word
FallThroughmode.IRindicateswhetherornottheFIFOhasavailablememory
locations. OR shows whether the FIFO has data available for reading or not.
It marks the presence of valid data on the outputs.
Each FIFO has a programmable Almost-Empty flag (
AEAandAEB)and
a programmable Almost-Full flag (
AFA and AFB). AEA and AEB indicate
when a selected number of words remain in the FIFO memory.
AFAand AFB
indicate when the FIFO contains more than a selected number of words.
FFA/IRA, FFB/IRB, AFA and AFB are two-stage synchronized to the
port clock that writes data into its array.
EFA/ORA, EFB/ORB, AEA and AEB
are two-stage synchronized to the port clock that reads data from its array.
Programmable offsets for
AEA, AEB, AFA and AFB are loaded by using
Port A. Three default offset settings are also provided. The
AEA and AEB
threshold can be set at 8, 16 or 64 locations from the empty boundary and the
AFAandAFBthresholdcanbesetat8,16or64locationsfromthefullboundary.
All these choices are made using the FS0 and FS1 inputs during Reset.
Two or more devices may be used in parallel to create wider data paths.
If, at any time, the FIFO is not actively performing a function, the chip will
automatically power down. During the power down state, supply current
consumption(ICC)isataminimum.Initiatinganyoperation(byactivatingcontrol
inputs) will immediately take the device out of the power down state.

°C to 70°C. Industrial temperature range (-40°C to +85°C) is available by
special order. They are fabricated using IDT’s high speed, submicron CMOS
technology.
