3.2 FT232H Pin Descriptions
This section describes the operation of the FT232H pins. Both the LQFP and the QFN packages have the
same function on each pin. The function of many pins is determined by the configuration of the FT232H.
The following table details the function of each pin dependent on the configuration of the interface. Each
of the functions is described in the following table (Note: The convention used throughout this document
for active low signals is the signal name followed by #).
Pins marked * are EEPROM selectable

Pins marked ** default to tri-stated inputs with an internal 75KΩ (approx) pull up resistor to VCCIO.
Pin marked *** default to GPIO line with an internal 75KΩ pull down resistor to GND. Using the EEPROM
this pin can be enabled USBVCC mode instead of GPIO mode.
