mode. IR indicates whether or not the FIFO has available memory 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 (
AEA and AEB) and a
programmable Almost-Full flag (
AFAandAFB). AEAandAEB indicatewhen
aselectednumberofwordsremainintheFIFOmemory.
AFAandAFBindicate
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
clockthatwritesdataintoitsarray.
EFA/ORA,EFB/ORB,AEAandAEBaretwo-
stage synchronized to the port clock that reads data from its array. Program-
mable offsets for
AEA,AEB, AFA and AFB areloaded byusingPortA.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
AFA and AFB
threshold can be set at 8, 16 or 64 locations from the full boundary. 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.
The IDT723652/723662/723672 are characterized for operation from 0
°C
to 70
°C.Industrialtemperaturerange(-40°Cto+85°C)isavailablebyspecial
order. They are fabricated using IDT’s high speed, submicron CMOS
technology.
