3.1
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.

Hardware description
UMFT12XEV Main Board
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
