to-HIGH transition of WCLK. Similarly, the
PAFisassertedLOWontheLOW-
to-HIGH transition of WCLK and
PAF is reset to HIGH on the LOW-to-HIGH
transition of RCLK.
If synchronous
PAE/PAF configuration is selected , the PAE is asserted
and updated on the rising edge of RCLK only and not WCLK. Similarly,
PAF
is asserted and updated on the rising edge of WCLK only and not RCLK. The
modedesiredisconfiguredduringmasterresetbythestateoftheProgrammable
Flag Mode (PFM) pin.
The Retransmit function allows data to be reread from the FIFO more
than once. A LOW on the
RT input during a rising RCLK edge initiates a
retransmitoperationbysettingthereadpointertothefirstlocationofthememory
array. A zero-latency retransmit timing mode can be selected using the
RetransmittimingModepin(RM).DuringMasterReset,aLOWonRMwillselect
zero-latency retransmit. A HIGH on RM during Master Reset will select normal
latency.
If zero-latency retransmit operation is selected the first data word to be
retransmitted will be placed on the output register with respect to the same
RCLK edge that initiated the retransmit based on RT being LOW.
Refer to Figure 11 and 12 for Retransmit Timing with normal latency. Refer
to Figure 13 and 14 for Retransmit Timing with zero-latency.
A Big-Endian/Little-Endian data word format is provided. This function is
useful when data is written into the FIFO in long word format (x18) and read
out of the FIFO in small word (x9) format. If Big-Endian mode is selected, then

outoftheFIFOfirst,followedbytheleastsignificantbyte.IfLittle-Endianformat
is selected, then the least significant byte of the long word written into the FIFO
will be read out first, followed by the most significant byte. The mode desired is
configured during master reset by the state of the Big-Endian (
BE) pin.
The Interspersed/Non-Interspersed Parity (IP) bit function allows the user
to select the parity bit in the word loaded into the parallel port (D0-Dn) when
programming the flag offsets. If Interspersed Parity mode is selected, then the
FIFOwillassumethattheparitybitislocatedinbitpositionD8 duringtheparallel
programmingoftheflagoffsets.IfNon-InterspersedParitymodeisselected,then
D8isassumedtobeavalidbitandD16 andD17 areignored.IPmodeisselected
during Master Reset by the state of the IP input pin. This mode is relevant only
when the input width is set to x18 mode. Interspersed Parity control only has
aneffectduringparallelprogrammingoftheoffsetregisters.Itdoesnoteffectthe
data written to and read from the FIFO.
A JTAG test port is provided, here the FIFO has fully functional Boundary
Scan feature, compliant with IEEE 1149.1 Standard Test Access Port and
Boundary Scan Architecture.
If, at any time, the FIFO is not actively performing an operation, the chip will
automatically power down. Once in the power down state, the standby supply
currentconsumptionisminimized.Initiatinganyoperation(byactivatingcontrol
inputs) will immediately take the device out of the power down state.
The IDT72V223/72V233/72V243/72V253/72V263/72V273/72V283/
72V293 are fabricated using IDT’s high speed submicron CMOS technology.
