4.1 Architecture
Fig. 4-1ETK-S20.1 Architecture
The microcontroller can communicate with the memories or peripheral compo-
nents of the development ECU. The ETK-S20.1 is connected to the serial debug
and test interface of the microcontroller (DAP). It converts these interface to
the 100 MBit/s serial ETK interface and extends in this way the length of the
connection line.

ETAS Hardware Description
ETK-S20.1 -User Guide 18
While the microcontroller accesses the data out of the data emulation memory,
the content of the data emulation memory can simultaneously be modified by
the calibration and development system through the serial ETK interface. This
process 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 send data to the calibra-
tion and development system which receives, buffers and processes this
measured data (DISTAB13).
The 100 Mbit/s serial interface provides communication with the calibration
and development system.
The power supply for the ETK-S20.1 is provided by a switch mode power sup-
ply, to minimize power dissipation.
4.2 ECU Interface
The ECU interface can be flexibly configured for several applications. For a HDC
update, it is not necessary to unmount or disconnect the ETK-S20.1 from the
ECU.
For currently supported microcontrollers refer to chapter 7.1.3 on page 36.
The ETK-S20.1 is connected via CON1 and CON2 to the ECU with two adapter
cables (refer to Fig. 4-2 on page 18). The pin definition depends on the applica-
tion and the microcontroller type. In general the ECU interface consists of
• 1 ECU voltage line, which is not used for ETK power supply but only for
detection of the ECU status, therefore the power consumption on these
line is negligible (refer to chapter 4.5 on page 20)
• 1 Reset line which allows the ETK to control the system reset of the ECU
• 7 Debug Interface lines for the communication between the ETK-S20.1
and the microcontroller
• 2 ground lines for a proper shielding of the ECU interface lines.

4.3 Serial ETK Interface
The serial 100 Mbit/s ETK-S20.1 interface creates the link to the calibration and
development system. The interface utilizes a 100Base-TX transmission to
achieve a transmission performance of 100 Mbit/s.
Fig. 4-3Location of the Serial ETK Interface (ETK-S20.1)
4.4 Debug Interface
The ETK-S20.1 features a DAP debugging interface connector CON5 (Samtec
16 pin). This connector can be used to attach debug tools (e.g. Lauterbach or
PLS debugger for Infineon TC2D5ED and TC27x-ED).
Fig. 4-4Location of the Debugger Interface (ETK-S20.1)
By using the debug interface for serial ETK connection, it is not available for
debugging tools anymore. Arbitration mechanisms are required to simultane-
ously work e.g. with measurement and calibration tools as well as with debug-
ging tools. The ETK-S20.1 supports a hardware arbitration unit for the DAP
interface. This enables parallel use of tools for debugging and ETAS tools for
measurement and calibration.
NOTE
To ensure stable communication only 100 Mbit cables delivered by ETAS
shall be used.

4.5 Power Supply
The ETK-S20.1 needs a permanent power supply. It is powered directly from
the car battery. The input voltage may vary between 5 V and 36 V (3 V drops for
3 seconds). In case of higher input voltages to the ETK an additional voltage
converter is required.
All necessary voltages are created through switching power supplies which
minimizes power dissipation. The power supply of the ECU is not affected by
the ETK-S20.1. An automatic switch ensures that the power supply of the ETK-
S20.1 is automatically switched on and off when the ETK enters and leaves its
sleep mode.
The ETK-S20.1 can be supplied with power through five pins connector CON7.
The 2 pin JST connector CON3 can be used additionally to connect a power
supply UBatt2. The power supply on CON3 must use the GND of CON7 (refer to
chapter 5.2.2).
Fig. 4-5Location of the Power Supply Connectors (ETK-S20.1)
4.6 ECU Voltage Supervisor
The ECU voltage (VDDP) is monitored by the ETK to recognize whether the ECU
is switched on or off. The ETK-S20.1 supplies the ECU EDRAM and monitores
this voltage.
NOTE
The ETK-S20.1 allow switching between reference page and working page
only, if there is a valid voltage at the sense pin detected.
