3.2 FT2232H Pin Descriptions
This section describes the operation of the FT2232H 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 FT2232H.
The following table details the function of each pin dependent on the configuration of the interface. Each
of the functions are described in the following table (Note: The convention used throughout this
document for active low signals is the signal name followed by a #).
Pins marked ** default to tri-stated inputs with an internal 75KΩ (approx) pull up resistor to VCCIO.
