Description
Module Ground Supply Pins
3.3V output from integrated LDO regulator. This pin is decoupled with a 100nF
capacitor to ground on the PCB module. The prime purpose of this pin is to
provide the 3.3V supply that can be used internally. For power supply
configuration details see section 5.
+1.8V to +3.3V supply to the UART Interface and CBUS I/O pins. For power
supply configuration details see section 5.

USB Cable Shield. Connected to GND via a 0ohm resistor.
5V Power output from the USB bus. For a low power USB bus powered design, up
to 100mA can be sourced from the 5V supply and applied to the USB bus. A
maximum of 500mA can be sourced from the USB bus in a high power USB bus
powered design. Currents up to 1A can be sourced from a dedicated charger and
applied to the USB bus.
5V power input for FT240X. For power supply configuration details see section 5.
FT231X active low reset line. Configured with an on board pull-up and
recommended filter capacitor. When no power is applied to the USB bus reset, will
be held low, this prevents current from flowing to the host or hub when in self-
powered mode.
Configurable CBUS I/O Pin. Function of this pin is configured in the device internal
MTP ROM. Factory Default pin Function is
Table 4.2.
Configurable CBUS I/O Pin. Function of this pin is configured in the device internal
MTP ROM. Factory Default pin Function is VBUS_Sense. See CBUS Signal Options,
