The CY7C63723C-PXC can support clock frequencies up to 67 MHz.
To implement FIFO mode, set the FIFOEN pin high and configure the device using the FIFO control registers. Refer to the datasheet for specific register settings.
The maximum data transfer rate of the CY7C63723C-PXC is 67 MB/s.
Yes, the CY7C63723C-PXC can be used as a UART. It has a built-in UART mode that supports data transfer rates up to 3 Mbps.
The CY7C63723C-PXC can be reset by asserting the RESET# pin low for at least 10 ns.
