Description
Can be used by an external device to reset the FT232R. If not required can be left
unconnected, or pulled up to VCCIO.
Configurable CBUS I/O Pin. Function of this pin is configured in the device internal
EEPROM. Factory Default pin Function is RXLED#. See CBUS Signal Options, Table
4.4.*
Configurable CBUS I/O Pin. Function of this pin is configured in the device internal
EEPROM. Factory Default pin Function is TXLED#. See CBUS Signal Options,Table 4.4.*
Table 4.1Module Pin Out Description
* When used in Suspend, these pins are pulled to VCCIO via internal 200k Ω resistors. These pins
can be programmed to gently pull low during USB suspend (PWREN # = “1”) by setting an option
in the internal EEPROM.

Description
5V Power output USB port. For a low power USB bus power design, up to 100mA can
be sourced from the 5V supply on the USB bus. A maximum of 500 mA can be sourced
from the USB bus in a high power USB bus powered design.
Board supply input. Connect to jumper J2 pin 1 in order to supply the board from the
USB bus.
This pin is internally connected to the VCC DIP pins. Remove the jumper connector in a
self powered design.
