Clearance No.: FTDI# 125

Figure 7.2 is also 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.

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. One of the CBUS pins could be configured as a 6/12/24/48 MHz clock

output which can be used to clock the MCU. 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.
