While the microcontroller accesses the program data (not the program code)
out of the data emulation memory provided by the microcontroller, the content
of the data emulation memory can simultaneously be modified by the calibra-
tion and development system through the XETK Ethernet interface. This pro-
cess enables adjustments of parameters, characteristic lines and maps

through the calibration and development system. Using an additional measure-
ment data memory area, the ECU microcontroller can provide data to the cali-
bration and development system by buffering the data (DISTAB13) and
triggering the XETK to read the data via JTAG. The XETK then reads, buffers,
processes and sends this measured data to the PC.
If no additional measurement data memory is available, the XETK-S21.0 can
alternatively read the data to be measured directly from the microcontroller’s
memory. This process is Triggered Direct Measurement (TDM) with DISTAB13.
The 100 Mbit/s XETK Ethernet interface provides communication with the PC.
The power supply for the XETK-S21.0 is provided by a switch mode power sup-
ply, to minimize power dissipation.
4.2 ECU Interface
The XETK-S21.0 is connected via connectors CON6 and CON7 to the ECU with
two adapter cables (refer to Fig. 4-2 on page 17). The pin definition depends on
the application and the microcontroller type. In general the ECU interface con-
sists 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 4.5 on page 20)
• 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
• 5 Debug line interfaces for the communication between the XETK-S21.0
and the microcontroller
• 2 ground lines for proper shielding of the ECU interface lines.

4.3 XETK Ethernet Interface
The XETK Ethernet interface can be directly connected to the PC via CON5
(refer to Fig. 4-3). 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 automatic 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-S21.0
with third party application softw are.
Fig. 4-3Location of the XETK Ethernet Interface connector (CON5)
NOTE
The XETK Ethernet interface is not compatible with the ETK interfaces in
modules 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 ES51x/ ES592/ ES593-D/
ES595/ ES600 modules.
NOTE
Please see chapter 7.1.2 on page 33 for additional information regarding PC
requirements for the Ethernet interface.

ETAS Hardware Description
XETK-S21.0B -User Guide 19
4.4 Debug Interface
The XETK-S21.0 features a JTAG debugging interface connector CON1 (Sam-
tec 16 pin). This connector can be used to attach debug tool (e.g. Lauterbach
or PLS debugger). It is recommended to use the ETAS Debug - Adapter (e.g.
ETAF11 or AS_ETAF13) to connect the debugger to the XETK.
Fig. 4-4Location of the Debugger Interface (XETK-S21.0)
By using the debug interface at the ECU board for serial ETK connection, it is
not available for debugging tools anymore. Arbitration mechanisms are
required to simultaneously work e.g. with measurement and calibration tools
as well as with debugging tools. The XETK-S21.0 provides a hardware arbitra-
tion unit for the JTAG interface. This enables parallel use of tools for debugging
and ETAS tools for measurement and calibration.
NOTE
When using the XETK-S21.0 and ETAF11, the debug tool will not be able to
control the watchdog timer disable pin or monitor the /ESR0 signal provided
by the XETK-S21.0 at CON1. The AS_ETAF13 enables the usage of the watch-
dog timer disable pin and /ESR0 signals.

4.5 Power Supply
The XETK-S21.0 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-S21.0 will also accept voltage dips down to 3V, for a max-
imum duration of 15ms (for additional details of low voltage operation, see ISO
standard 16750)
From the input battery voltage, the XETK-S21.0 creates all necessary voltages
through switching power supplies on the XETK-S21.0. The power supply of the
ECU is not affected by the XETK-S21.0. An automatic switch ensures that the
power supply of the XETK-S21.0 is automatically switched on and off when the
XETK enters and leaves its standby (sleep) mode.
The XETK-S21.0 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.
