Introduction - XE166 family
Hardware Manual 5 V1.5, 2011-03
1 Introduction - XE166 family
XE166 family - More performance, more Flash, better peripherals
With more than 15 successful years in the microcontroller market place, C166 has set the standard for 16-bit
architectures with the highest aggregate volume share of all available 16-bit devices.
With its fast interrupt response and context switching, the C166 family is ideally suited for automotive, industrial,
mass storage and wired as well as wireless communications applications.
Compared with the XC166, XE166 delivers more performance, more Flash memory, more RAM, strongly
enhanced peripherals and a complete DSP library.
MCU and DSP in a core
Infineon Technologies´ Real Time Signal Controller combines the traditional strengths of a Microcontroller Unit
(MCU) to control peripherals with the computing power of Digital Signal Processors (DSP). All in one enhanced
C166S V2 core. Together, the Microcontroller's real-time capability and ease of use and the DSP's mathematical
performance and data throughput form a powerful singe-chip solution ideal for many embedded applications.
For detailed technical information about the different derivatives please refer to the XE166 family web pages on
the Infineon Internet.
http://www.infineon.com/XE166
This document covers all products of the XE162xL, XE161xL, XE161FU and XE160FU series.

2.4 DIP Switch S101
Although most of the programmable features of the XE166 are selected by software either during the initialization
phase or repeatedly during program execution, some features must be selected earlier because they are used for
the first access of the program execution.
These configurations are accomplished by latching the logic levels at a number of pins at the end of the internal
reset sequence.
DIP switch S101 allows to configure the startup setting of the XE166 during RESET. The default System Startup
Configuration is shown in Table 1. By default all DIP Switches are OFF. The XE166 executes a standard start from
internal Flash.
Note: The Kit is programmed with BMI for DAP. To connect a JTAG debugger box from a Tool vendor (KEIL, PLS),
the BMI need to be reprogrammed to JTAG using a flash programming software (e.g. Memtool).

2.4.1 Basic Startup Configuration for XE16x (L/ U -Series)
Configuration pins are treated by firmware differently depending on additional conditions:
1. If TRST=0 - it is purely hardware controlled (so-called “Zero-pin”) configuration - device start from Internal Flash
without debug support is executed
2. If TRST=1 - the Boot Mode Index (BMI) is evaluated by firmware first and depending on the result - start-up
mode and debug
For more detailed information about the DIP switch setting, please refer to Chapter 3.1.1, Table 4.
2.5 USB Drive installation
All USB-Transaction are realized by the USB-Software running on a Host-Computer. The USB-Device driver is
communicating with the Equipment connected to the Computer.
The driver for Easy Kit USB interface will be delivered with a Software called DAS (Device Access Server). The
goal of the DAS architecture is to provide one single interface for all types of tools, which fulfills all performance
and reliability needs. Additionally a driver for a virtual COM port will be installed.
Find out more about DAS on the Infineon Web page:
http://www.infineon.com/DAS
This DAS Software can be found in the Easy Kit CD under the Tools section. DAS Software Version 3.0.0 or higher
is required to be used with the Easy Kit.

2.6 Easy Kit Power Supply concept
The Easy Kit USB Power Supply concept allows the user to work with the Kit without an external Power Supply.
If the USB power supply is not sufficient, an additional regulated DC power supply can be used.
Figure 5 Easy Kit Power Supply concept
By means of the Power Supply Jumper JP201, USB, or the external power Supply can be selected to run the Easy
Kit. The Setup for the Jumper JP201 is shown in Table 3 below.
The USB specification provides a 5 V supply on a single wire from which connected USB devices may draw power.
The specification provides for no more than 5.25 V and no less than 4.35 V between the +ve and -ve bus power
lines.
Initially, a device is only allowed to draw 100 mA. It may request more current from the upstream device in units
of 100 mA up to a maximum of 500 mA. In practice, most ports will deliver the full 500 mA or more before shutting
down power, even if the device hasn't requested it or even identified itself. If a (compliant) device requires more
power than is available, then it cannot operate until the user changes the network (either by rearranging USB
connections or by adding external power) to supply the required power.

Note: If the USB power supply is not sufficient, an external power supply is needed and the Jumper JP201 setting
need to be changed.
Note: In case the USB Host PC goes into Suspend Mode, an external Power Supply should be used.
2.6.1 Power Supply via Power Plug
The XE166 Board can be supplied either with USB cable or with an external power supply. For external power
supply, a regulated DC power supply with max. 12Volt/ 400mA can be connected to the power connector. The
maximum power dissipation of the used voltage regulator has to be taken into account.
Figure 6 Power Supply

3 Information in Detail
The XE166 family supports variety of start-up modes, allowing the user to make selections in three aspects:
• Main functionality - where from the user code will be started (on-chip Flash, PSRAM, external memory);
• Optionally - a way for initial code-downloading into PSRAM before to start it:
– From an external host via a communication interface - UART, CAN.
• Debug-related - either debugging will be possible, and if Yes - which debug-interface to use (SPD, JTAG, and
DAP selectable pin-assignments via BMI).
The Easy Kit Board Manual covers only a limited number of start-up modes. For all possible start-up modes please
refer to the corresponding User’s Manual.

3.2.3 LIN Interface (X105)
The board has a connector with 4 pins for LIN. For the pinout of the connector see Figure 9. The LIN transceiver
is connected to USIC1 Channel 0 for XE16xL module, and USIC0 Channel 0 for XE16xU module of the CPU.
Figure 9 On-board header (X105)
3.2.4 OCDS Interface
The OCDS1 signals are connected to the IDC16 plug (X202). For pinout of the connector see Figure 10. You can
connect any debugger to this connector.
The signals /BRKIN and /BRKOUT are not connected by default.
If you connect a debug hardware, ensure that the MiniWiggler circuit is not active (ACTIV LED is off), and on the
DAP connector (X203), no hardware is connected or the hardware is tristate.
If the ACTIV LED is on, then stop the active DAS Server JTAG over USB Chip and/or remove the USB connection
to the PC.
Figure 10 On-board header X202
3.2.5 DAP Interface
The board comes with a DAP connector (X203). For pinout of this connector see Figure 11. You can connect a
DAP/ SPD hardware here. If you use this connector make sure that the MiniWiggler is not active (ACTIV LED is
off) and a connected OCDS1 hardware is disconnected or tristate.
For single pin DAP (SPD) interface, DAP1 is used.
