and Read Enable (
REN) input. Data is read from the FIFO on every rising
edgeofRCLKwhen
RENisasserted. AnOutputEnable(OE)inputisprovided
for three-state control of the outputs.
The frequencies of both the RCLK and the WCLK signals may vary from 0
tofMAXwithcompleteindependence. Therearenorestrictionsonthefrequency
of the one clock input with respect to the other.
There are two possible timing modes of operation with these devices: IDT
Standard mode and First Word Fall Through (FWFT) mode.
InIDTStandardmode,thefirstwordwrittentoanemptyFIFOwillnotappear
on the data output lines unless a specific read operation is performed. A read
operation,whichconsistsofactivating
RENandenablingarisingRCLKedge,
will shift the word from internal memory to the data output lines.
In FWFT mode, the first word written to an empty FIFO is clocked directly
to the data output lines after three transitions of the RCLK signal. A
RENdoes
not have to be asserted for accessing the first word. However, subsequent
words written to the FIFO do require a LOW on
REN foraccess. Thestateof
the FWFT/SI input during Master Reset determines the timing mode in use.
For applications requiring more data storage capacity than a single FIFO
canprovide,theFWFTtimingmodepermitsdepthexpansionbychainingFIFOs
in series (i.e. the data outputs of one FIFO are connected to the corresponding
data inputs of the next). No external logic is required.
