7.4 USB to MCU UART Interface

Figure 7.4 USB to MCU UART Interface

An example of using the FT232RN as a USB to Microcontroller (MCU) UART interface is shown in Figure 7.4.

In this application the FT232RN uses TXD and RXD for transmission and reception of data, and RTS# /

CTS# signals for hardware handshaking. In this example CBUS0 has been configured as a 12MHz output

to clock the MCU (the clock will stop when in suspend mode).

Optionally, RI# could be connected to another I/O pin on the MCU and used to wake up the USB host

controller from suspend mode. If the MCU is overseeing power management functions, then a CBUS pin

can be configured as PWREN# and would also be connected to an I/O pin of the MCU.
