Introduction
1.1
Features
USB2.0 Full Speed compatible
USB bus powered
USB Type B micro connector for
connecting to a PC
USB Type A connector for connecting to a
UMFT4222EV or a device with a FT4222H
On board FTDI chip provides USB hub
function
Visual indicator for 6.5V programming
voltage and USB bus power using LEDs
The UMFT4222PROG FT4222H Programmer
Module is used to program OTP memory on a
UMFT4222EV or devices with a FT4222H.
The internal OTP memory in the FT4222H is used
to store USB Vendor ID (VID), Product ID (PID),
device serial number, product description string
and various other USB configuration descriptors.
With this embedded OTP memory, the device can
store vendor specific information and save the
cost on BOM.
The 4 pin connector on the module connects
directly to the FTDI UMFT4222EV. The
UMFT4222PROG allows the user to program the
UMFT4222EV OTP memory from a USB host
controller.

FT4222H Programmer Module
3
Function Description
The FT4222H Programmer Module (UMFT4222PROG) is designed to control VPP power output (+6.5V) for
programming the FT4222H OTP memory on the UMFT4222EV module or custom device with a FT4222H.
This module is USB bus-powered and includes a USB 2.0 compliant full speed hub device. The VPP power is
provided from the USB upstream port.
VPP power is supplied through 2 pins of the 2.54mm pitch header, JP1. There are two USB connectors: 1)
CN1: USB Type B micro receptacle to a PC, 2) CN2: USB Type A receptacle to a UMFT4222EV or custom
FT4222H device.
Having connected the UMFT4222PROG module, the user can perform the OTP memory programming with
FT_PROG software. FT_PROG is a free programming utility for use with FTDI devices. For more details,
please refer to the
FTDI website.
