IDT723616 CMOS TRIPLE BUS SyncFIFO
WITH
BUS-MATCHING AND BYTE SWAPPING 64 x 36 x 2
This FIFO employs IDT Standard Mode timing; that is to say, the first word
written to an empty FIFO is deposited into the memory array. A read operation
is required to access that word (along with all other words residing in memory).
Each FIFO has an Empty Flag (
EFA and EFB) and a Full Flag (FFA and
FFC). EF indicates whether or not the FIFO memory is empty. FF shows
whether the memory is full or not.
Each FIFO has a programmable Almost-Empty flag (
AEA and AEB) and a
programmable Almost-Full flag (
AFAandAFC). AEAandAEBindicatewhen
a selected number of words written to FIFO memory achieve a predetermined
"almost-emptystate".
AFAandAFCindicatewhenaselectednumberofwords
written to the memory achieve a predetermined "almost-full state".
FFA, FFC,AFA andAFC aretwo-stagesynchronizedtotheportclockthat

EFA,EFB,AEA,andAEBaretwo-stagesynchronized
to the port clock that reads data from its array. Four default offset settings are
alsoprovided.The
AEAandAEBthresholdcanbesetat4,8,12or16locations
from the empty boundary and the
AFA and AFC threshold can be set at 4, 8,
12 or 16 locations from the full boundary. All these choices are made using the
FS0 and FS1 inputs during Reset.
Two or more FIFOs may be used in parallel to create wider data paths. Such
a width expansion requires no additional, external components.
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) is at a minimum. Initiating any operation (by activating
control inputs) will immediately take the device out of the Power Down state.
The IDT723616 are characterized for operation from 0°C to 70°C. They
are fabricated using IDT’s high speed, submicron CMOS technology.
