Table 3.2 FT2232H-56Q Mini Module Connection – CN3

In most cases, the FT2232H-56Q pin is connected directly to the associated pin on CN2 or CN3.

The FT2232H-56Q Mini Module allows configuration with both USB Bus-powered designs and USB Self-

powered designs:

USB Bus-powered:

1) JP1 is connected VBUS to VCC (CN3, pin 1 to CN3, pin 3). This connection takes the power

from the USB bus (VBUS) and connects it to the voltage regulator input on the FT2232H-56Q Mini

Module. The voltage regulator, in turn, provides V3V3, VPLL and VUSB power inputs to the

FT2232H-56Q chip.

2) JP2 is connected V3V3 to VIO (CN2, pins 1, 3 & 5 to CN2, pins 11 and CN3, pins 12 &

22). This connection provides the correct 3.3VDC operating voltage for VCCIO on the FT2232H-

56Q chip.

3) Connected to jumper JP1 pin 1 in order to supply power for FT2232H-56Q chip from the USB

port.

4) External 3.3V regulator output. Connected to jumper JP2 pin 2 in order to supply the VIO voltage

with 3.3V tolerance.
