• Manufacturer Part Number: ft232hq
• Description: Ft232h Single Channel Hi- Speed Usb To Multipurpose Uart/fifo Ic
• Manufacturer: Future Technology Devices International Ltd.

Note:
1. In this application, pin 40 (VREGIN) is the +5V input to the on chip +3.3V/1.8V regulator.
2.
Since the VREGIN is +5.0V, pin 39 (VCCD) becomes 3V3 output and supplies 3.3V to the
VCCIOs, VPLL and VPHY.
The output of the on chip LDO +3.3V/1.8V regulator (+1.8V) drives pin 38, the
FT232H core supply (VCORE) and pin 37, the VCCA.
