adjustments of parameters, characteristic lines and maps through the calibration
and development system. Using an additional measurement data memory area,
the ECU microcontroller can provide data to the calibration and development sys-
tem by buffering the data (DISTAB) and triggering the XETK to read the data via
DAP. The XETK then reads, buffers, processes and sends this measured data to
the PC.
If no additional measurement data memory is available, the XETK-S20.1B can alter-
natively read the data to be measured directly from the microcontroller’s memory.
This process is Triggered Direct Measurement (TDM).
The 100 Mbit/s XETK Ethernet interface provides communication with the PC.
The power supply for the XETK-S20.1B is provided by a switch mode power supply,
to minimize power dissipation.
3.2 ECU Interface
The XETK-S20.1B is connected via connectors CON6 and CON7 to the ECU with
two adapter cables (refer to Fig. 3-2 on page 16). The pin definition depends on the
application and the microcontroller type. In general the ECU interface consists of
- 1 ECU voltage line, which is not used for XETK power supply, but only for
detection of the ECU status, therefore the power consumption on this line is
negligible (refer to chapter 3.5 on page 19)
- 1 Reset line which allows the XETK to control the system reset of the ECU
- 1 Reset line which allows the XETK to monitor the system reset of the ECU
- 3 Debug line interfaces for the communication between the XETK-S20.1B
and the microcontroller (/TRST, DAP0, DAP1)
- 2 ground lines for proper shielding of the ECU interface lines

3.3 XETK Ethernet Interface
The XETK Ethernet interface shown in Fig. 3-3 can be directly connected to the PC.
No additional ETAS module is required for the access to the ECU.
The interface is a standard full duplex 100Base-TX Ethernet interface using the XCP
protocol. The XETK Ethernet interface is integrated in the ETAS IP world with auto -
matic IP management and supports the open automotive "Universal Measurement
and Calibration" standard "XCP on Ethernet" (TCP/IP, UDP/IP). The open XCP on
Ethernet interface allows for connecting to the XETK-S20.1B with third party appli -
cation softw are.
Fig. 3-3Location of the XETK Ethernet Interface connector (CON5)
NOTE
The XETK Ethernet interface is not compatible with the ETK interfaces in mod-
ules like e.g. ES910, ES590, ES591, ES592, ES593-D, ES595, ES1232-A. The XETK
Ethernet interface is compatible with the ECU interface of the ES910 module and
the Ethernet interfaces of the ES592/ ES593-D/ ES595/ ES600/ ES8xx modules.
NOTE
Please see chapter 6.1.2 on page 32 for additional information regarding PC
requirements for the Ethernet interface.

3.4 Debug Interface
The XETK-S20.1B features a DAP debugging interface connector CON1 (Samtec 16
pin). This connector can be used to attach debug tools (e.g. Lauterbach or PLS
debugger for Infineon TC27x-ED and TC29x-ED).
Fig. 3-4Location of the Debugger Interface (XETK-S20.1B)
By using the debug interface at the ECU board for serial ETK connection, it is not
available for debugging tools any longer. Arbitration mechanisms are required to
simultaneously work e.g. with measurement and calibration tools as well as with
debugging tools. The XETK-S20.1B provides a hardware arbitration unit for the DAP
interface. This enables parallel use of tools for debugging and ETAS tools for mea-
surement and calibration

3.5 Power Supply
The XETK-S20.1B requires a permanent power supply. It is typically powered
directly from the car battery. The input voltage may vary between 4.3 V and 36 V. In
case of higher input voltages to the XETK, additional voltage protection is required.
The XETK-S20.1B will also accept voltage dips down to 3V, for a maximum duration
of 15ms (for additional details of low voltage operation, see ISO standard 16750).
From the input battery voltage, the XETK-S20.1B creates all necessary voltages
through switching power supplies on the XETK-S20.1B. The power supply of the
ECU is not affected by the XETK-S20.1B. An automatic switch ensures that the
power supply of the XETK-S20.1B is automatically switched on and off when the
XETK enters and leaves its standby (sleep) mode.
The XETK-S20.1B can be supplied with power through the seven pin connector,
CON7. The through-hole solder pad CON4 can be used additionally to connect a
power supply UBatt2.
The power supply on CON4 must use the GND of CON7 pin 3.
Fig. 3-5Location of the XETK-S20.1B Power Supply Connectors
3.6 ECU Voltage Supervisor
The ECU voltage (VDDP) is monitored by the XETK to recognize whether the ECU is
switched on or off.
Additionally the ECU RAM standby voltage (VDDSBRAM) is monitored to determine
if the standby RAM content is still valid. These two signals are only used for moni-
toring therefore the load current is negligible.
The XETK-S20.1B supplies the ECU EDRAM using the pin VDDSBRAM and monitors
this voltage using a sense pin on board the XETK. The microcontrollers standby
power supply pin must be connected to the XETK pin VDDSBRAM.
NOTE
The XETK-S20.1B only allows switching between reference page and working
page if there is a valid voltage at the sense pin and the working page has been
initialized by the calibration and development system.
