Table 4.1 FT245 Synchronous FIFO Interface Signal Timings
This single channel mode uses a synchronous interface to get high data transfer speeds. The chip drives a
60 MHz CLKOUT clock for the external system to use.
Note that Asynchronous FIFO mode must be selected on both channels before selecting the Synchronous
FIFO mode in software.
4.4.1 FT245 Synchronous FIFO Read Operation
A read operation is started when the chip drives RXF# low. The external system can then drive OE# low
to turn around the data bus drivers before acknowledging the data with the RD# signal going low. The
first data byte is on the bus after OE# is low. The external system can burst the data out of the chip by
keeping RD# low or it can insert wait states in the RD# signal. If there is more data to be read it will
change on the clock following RD# sampled low. Once all the data has been consumed, the chip will drive
RXF# high. Any data that appears on the data bus, after RXF# is high, is invalid and should be ignored.
4.4.2 FT245 Synchronous FIFO Write Operation
A write operation can be started when TXE# is low. WR# is brought low when the data is valid. A burst
operation can be done on every clock providing TXE# is still low. The external system must monitor TXE#
and its own WR# to check that data has been accepted. Both TXE# and WR# must be low for data to be
accepted.
