Power Supply
If more current is needed, a regulated DC power supply with max. 12 Volts should be connected to the power
connector. The maximum power dissipation of the used voltage regulator has to be taken into account. By default
one green LED should be active. It indicates that the embedded voltage regulator supply the microcontroller.
Please Note, the power supply is not part of the delivery !

OCDS Debugging Interface
The XE166 Easy Kit offers two types of JTAG interfaces. With the FTDI chip an on board USB JTAG wiggler has
been implemented. Further the USB interface allows to emulate a USB to UART bridge. Both can be done at the
same time.
A simple 16 pin JTAG header can be used to connect a debugger from one of Infineon’s tool suppliers. Both
systems include an On-Chip Debug Support (OCDS) system, which provides convenient debugging, controlled
directly by an external device via debug interface pins.

USB Interface for UART support
The USB connector is used for connection to a PC. Via the USB it is possible to power the board, using the ASC0
as serial connection via USB and Debugging via DAS. For the pinout of USB socket see Figure 6.
NOTE: Before connecting the board to the PC, make sure that the actual DAS software is installed on the PC. For
actual DAS software please contact your local FAE.
The latest version of the software can also be found on the
