3 Hardware description
3.1 UMFT12XEV Main Board
The UMFT12XEV board is intended for use as a hardware platform to enable easy evaluation of FTDI’s
FT120, FT121 and FT122 series of USB peripheral controllers. The UMFT12XEV boards utilize a NXP
Cortex-M0 based microcontroller (LPC1114) to interface to FT12 series with parallel or SPI bus. The LEDs
and push buttons can be used to demo the HID keyboard functions. A prototype area is also built on the
UMFT12XEV board, allowing user defined application circuit to be added so that application
hardware/firmware can be developed and tested on the prototype before porting over to mass
production.
Figure 3-1 shows the PCB layout with main component positions. These components include:
- 14x2 socket for add-on module: insert any of the three daughter boards (UMFT120DC,
UMFT121DC, UMFT122DC)
- 3.3V Regulator: It takes 5V input from USB Vbus (bus-power) or DC jack CN4 (self power) and
output 3.3V for on-board circuits
- LED(GPIO): 2 LED diodes for GPIO status display. Can be used for HID keyboard status LED
- LED(BCD_DET): This LED indicates if a USB Charger is attached and detected by FT121/FT122
- Push Button(GPIO): 2 push buttons for GPIO control input. Can be used for HID keyboard
function keys
- Reset button: hardware reset button
- UART connector: This 6-pin UART connector can be used for in-system firmware download as well
as firmware debug port
- SPI0 connector: This 6-pin SPI connector can be used to connect to a SPI slave board
- JTAG/SWD connector: This 8-pin connector is for connecting to LPC-link for firmware download or
debug purpose
- LPC1114 Microcontroller: 44-pin LPC1114 Cortex-M0 MCU to control FT12x and other peripherals
- Prototype area: for adding extra application circuits for prototyping purpose

4.3 Install the driver
The LPC1114 on the UMFT12XEV board is pre-loaded with firmware supporting Communication Device
Class (CDC class). The major OSs support the CDC protocol on their USB stack to use serial port
communication, allowing PC’s to access the CDC device through a virtual COM port (VCP) without
developing a new driver.
Linux recognize the CDC device as /dev/ttyACM# (# denotes a number). The driver is loaded
automatically when the device is connected.
Mac OS recognize the CDC device as /dev/cu.usbmodem# (# denotes a number). The driver is loaded
automatically when the device is connected.
Windows has a CDC protocol driver (usbser.sys) to generate VCP. However, it requires a “Setting
Information (INF)” file at the first connection. The required INF file can be download from FTDI website
http://www.ftdichip.com/Products/Modules/DevelopmentModules.htm.
Here is an example of driver installation under Windows 7 32-bit system:
Connect the daughter card USB connector to the test PC with the micro-USB-B to Standard-A cable

5 Running demo tests
The UMFT12XEV is pre-loaded with a default firmware. The firmware can auto-detect the daughter card
type, and the LPC1114 MCU can communicate to the FT12 series with either SPI(for FT121) or parallel
(for FT120 or FT122) protocol. For bus-powered configuration (default setting), the FT12x evaluation kit
will power on when the USB cable is plugged in. LED D4 (red) on the main board will be ON, indicating
the 3.3V power is ready. The D2 and D3 LEDs (red) will be flashing, indicating the firmware is up and
running. For UMFT120DC and UMFT122DC, the LED D1 (green) on the daughter card will be tunred ON
upon successful enumeration, and blinking when there are USB transactions.
The default firmware supports USB CDC class driver. Upon enumeration a virtual COM port is present on
the PC. User can run serial port applications such as serial loopback test, teraterm, hyperterm etc.
5.1 Serial Loopback test
Follow the steps below to run the serial loopback test over the FT12x USB serial port interface.
- Install the serial loopback test utility. Download v1.10 of the serial loopback test utility at
http://www.madsencircuits.com/serial_loopback.html .
- Start the loopback test by clicking All Programs -> Serial Loopback Test -> Serial Loopback
Test.
- Select the Serial Port number from the pull-down list. In this example COM25 is selected.
- Click “Start Test” button. The utility will send data to the FT12x USB serial port, receive
back from the same serial port, and perform the comparisson of the received data from the
sent one. The FT12x Evaluation kit firmware will route all the received data back to the PC
internally (the firmware will store the data from bulk OUT endpoint, and send it back when
the bulk IN token comes).
Figure 5-1 Serial Loopback Test
5.2 USB Charger test
The FT121 and FT122 supports USB Charger (Wall Charger or Dedicated Charging Port) detection. The
USB Charger shall have micro-B plug with its D+/D- pins shorted.

Follow the steps below to check the USB Charger detection function:
- Connect the USB Charger to the micro-B USB connector of UMFT121DC or UMFT122DC
module.
- Plug the USB Charger to the Wall power socket and switch on the power.
- The yellow LED (D1 on the UMFT12XEV main board) will be turned ON. This indicates a
USB wall charger or dedicated charging port is connected.

7 Firmware Upgrade Process
The firmware for the on-board microcontroller LPC1114 can be upgraded through either UART (ISP mode)
or JTAG/SWD interface. This section will describe the steps on how to download the firmware through
ISP mode. For the usage of JTAG/SWD interface with LPC-Link debug module, please refer to NXP
LPCXpresso homepage at http://ics.nxp.com/lpcxpresso/. Note that the LPCXpresso is an integrated
development platform for firmware development, debug and download for NXP’s ARM-based LPC
microcontrollers. The LPCXpresso development tool chain can be downloaded from
http://lpcxpresso.code-red-tech.com/LPCXpresso/ .
Check the FTDI website for the available pre-compiled firmware for FT12x Evaluation Kit (
http://www.ftdichip.com/Firmware/Precompiled.htm ).
7.1 Put LPC1114 microcontroller in ISP mode
- Use a jumper wire to short pad 38 of J1 to pad 1 or pad 54 of J1. This is to connect the LPC1114
P0_1 pin to GND so that LPC1114 will enter ISP mode after power on or reset.
- Connect the board to the test PC via the micro-USB cable. The USBA plug shall be inserted in
the PC USB port, while the micro-USB-B plug shall be connected to the daughter card USB port.
The board will be powered on with the LPC1114 entering ISP mode. Note for self power
configuration the daughter card is not required to be present for firmware upgrading. For bus
power configuration the daughter card is required as the power comes from the daughter card
USB port.
Figure 7-1 Plug in micro USB cable
7.2 Connect the TTL-232R-3V3 cable
- Connect the board to the test PC using a TTL-232R-3V3 cable. Plug the 6-pin socket of the cable
into the CN2 pin header. Please note the direction of the cable, the black wire (GND) should be
plugged in to pin 1 of CN2.
- Connect the other end of the TTL-232R-3V3 cable to a USB port of the test PC

Figure 7-2 Connect TTL-232R-3V3 UART cable
7.3 Upgrade firmware
- Download and install the driver for the FTDI TTL-232R-3V3 cable. Refer to the cable datasheet for
details ( http://www.ftdichip.com/Support/Documents/DataSheets/Cables/DS_TTL-
232R_CABLES.pdf )
- Download the Flash Magic firmware programming utility from http://www.flashmagictool.com.
- Install the utility on test PC by running “FlashMagic.exe”
- Once installation is complete, launch the utility from Start -> All Programs -> Flash Magic ->
Flash Magic.
- Configure the tool by the following steps:
o Click “Select Device…”, choose LPC1114/302 from the popup window and click OK
o COM port: select the COM port number associated with the TTL-232R-3V3 cable. The
COM port number can be found in the “Device Manager -> Ports (COM & LPT) -> USB
Serial Port (COM3)”. Note on different PC this number can be changed.
o Interface: select “FTDI USB-Dongle” from the pull-down list.
o Oscillator (MHz): key in ‘12’.
o Tick the box “Erase blocks used by Hex File”.
o Select Hex File: browse to select the desired firmware binary hex file (ie “LPC1114-
FT12x.hex”).
o Tick the box “Verify after programming”
o The tool is configured ready for firmware downloading.
- Click “Start” button and the firmware download will begin. Typically the download takes about 2
minutes. Once completed, a ‘finished’ message will be displayed in the status bar (bottom side),
and the green download progress bar will reach 100%. Note the ‘finished’ message may
disappear after a while. If no message is displayed in the status bar after a few minutes, this also
indicates that the previous download is completed.
- Power off the board. Remove the ISP jumper wire and then power on the board again. The new
firmware will take effect.
