GROUND
RTS - Request to Send Control Output/Handshake Signal
RI - Ring Indicator Control Input. When remote wake-up is enabled in the internal
EEPROM taking RI# low (20ms active low pulse), this can be used to resume the PC
USB host controller from Suspend.
DSR - Data Set Ready Control Input/Handshake Signal
CTS - Clear To Send Control Input/Handshake Signal
CBUS4 - Configurable CBUS output-only pin. The function of this pin is configured in the
FT232R internal EEPROM (see CBUS Signal Options in the next section).
VCCIO - +1.8V to +5.25V supply for the UART interface and CBUS group (Pins 6, 11,
12, 14 and 15). Connect this pin to an external power supply to drive out at +3.3V levels
(or another voltage within the specified range), or connect to EXTVCC (Pin 8) to drive out
at the +5V CMOS level.
EXTVCC - Use for applying main power (4.0 to 5.25 volts) to the module. Connect to
PORTVCC (Pin 9) if the module is to be powered by the USB port (typical configuration).
PORTVCC - Power from the USB port. Connect to EXTVCC (Pin 8) if the module is to
be powered by the USB port (typical configuration). 500mA is the maximum current
available to the USB adapter and target electronics if the USB device is configured for
high power.
GROUND
CBUS2 - Configurable CBUS I/O pin. The function of this pin is configured in the
FT232R internal EEPROM (see CBUS Signal Options in the next section).
CBUS3 - Configurable CBUS I/O Pin. The function of this pin is configured in the
FT232R internal EEPROM (see CBUS Signal Options in the next section).
DCD - Data Carrier Detect Control Input
CBUS1 - Configurable CBUS I/O Pin. The function of this pin is configured in the
FT232R internal EEPROM (see CBUS Signal Options in the next section).
CBUS0 - Configurable CBUS I/O Pin. The function of this pin is configured in the
FT232R internal EEPROM (see CBUS Signal Options in the next section).
RXD - Receiving Asynchronous Data Input
DTR - Data Terminal Ready Control Output/Handshake Signal
TXD - Transmit Asynchronous Data Output
