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 I
configuration details see section 5.
FT201X 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 IC‟s internal MTP
ROM. See CBUS Signal Options, Table 4.2.
Configurable CBUS I/O Pin. Function of this pin is configured in the IC‟s internal MTP
ROM. See CBUS signal options,Table 4.2.

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 FT201X. For power supply configuration details see section 5.
