Figure -Example USB to MCU UART Interface
Figure is an example of interfacing the FT232R to a Microcontroller (MCU) UART interface. This example uses TXD and RXD for transmission and reception of data, and RTS# / CTS# hardware handshaking. Also in this example CBUS0 has been configured as a 12MHz output which is being used to clock the MCU.
Optionally, RI# can be connected to another I/O pin on the MCU and could be used to wake up the USB host controller from suspend mode. If the MCU is handling power management functions, then a CBUS pin can be configured as PWREN# and should also be connected to an I/O pin of the MCU.
