UM232H Single Channel USB Hi-Speed FT232H Development Module

Datasheet Version 1.2

Clearance No.: FTDI# 198

The following 2 tables provide a description of the signals available on each pin of the UM232H module

Pin No. Name Type

Description

J1-1

GND

PWR

Module Ground Supply Pins

J1-2

5V0

Input

+5.0V or +3.3V power supply input.

J1-3

USB

Output

J1-4

RST# Input

5V Power output USB port. For a low power USB bus powered design, up to

100mA can be sourced from the 5V supply on the USB bus. A maximum of

500mA can be sourced from the USB bus in a high power USB bus powered

design.

Can be used by an external device to reset the FT232H. If not required can be

left unconnected, or pulled up to VCCIO
