FETK-S1.1A / FETK-S1.1B

The FETK-S1.1A and FETK-S1.1B are ETK for the Infineon AURIX microcontroller family.

These serial ETK can be used for measurement and calibration applications, rapid prototyping, and flashing.

Configuration Parameters

The following list shows the parameters for the FETK-S1.1A and FETK-S1.1B device:

Defines the type of the microcontroller used in the ECU.

Defines the frequency used for the DAP interface.

Defines whether 1 data pin (DAP1 (2Pin-DAP)) or 2 data pins (DAP2 (3Pin-DAP)) are used. DAP2 supports a higher data rate than DAP1 via the DAP interface.

Selects how the XETK controls the ECU watchdog.

  • Controlled by ECU: The XETK will not drive the signal.
  • Enabled: Enables watchdog control from the XETK debugger connector. The XETK will drive the signal as configured to enable the watchdog when the debugger requests the watchdog to be enabled.
  • Disabled: The XETK will drive the signal as configured to disable the watchdog.

Controls which level of the watchdog disable signal shall disable the watchdog.

  • Low: Low level shall disable the watchdog.
  • High: High Level shall disable the watchdog.

The ETK has the ability to wake up the ECU by applying voltage to the CalWakeUp pin of the ECU connector. This makes it possible to download the content of the working page and configure a measurement while the ECU is off.

When waking up the ECU via the CalWakeUp pin it can be selected whether the pin is pulled until the microcontroller core voltage (VDDP) is high or whether the pin should be kept on high state until the start-up handshake between ECU and ETK signals to the ETK that the ECU has finished its initialization.

  • YES: The CalWakeUp pin will be kept on high state until the start-up handshake between ECU and ETK signals to the ETK that the ECU has finished its initialization.
  • NO: The CalWakeUp pin is pulled until the microcontroller core voltage (VDDP) is high.

Selects the signal the ETK will use for ECU standby RAM (working page) power supply supervision.

  • ETK Standby Supply: ETK is monitoring the standby supply it provides to the ECU.
  • No Standby Supply: ETK is monitoring the standard ECU power supply; the working page is not using a standby supply.

Configures whether the ECU is set into reset during ETK sleep. This may improve the handshake after wakeup.

Select the timeout value for the handshake.

  • Infinite: This option must be selected for Register Triggering.
  • timeout values (1 ms, 10 ms, …): Select one of the timeout values if Timer Triggering is used. ETK will report a simulated successful handshake completion to the software after the selected time has elapsed.

Selects the polling rate in μs. Typically at least twice as fast as the fastest raster in a measurement.

Defines how the XETK shall behave if an overload occurs during data processing.

  • Drop Data and Continue Measurement: The XETK drops measurement data, sends an error event and continues measurement.
  • Stop Measurement: The XETK stops the measurement and sends an error event.

Only FETK-S1.1B:

Defines how the ETK will configure the microcontroller’s DAP timeout value. When the microcontroller’s internal bus is under high load, it takes additional time to read or write data using the DAP Interface. To reduce the chance of a DAP timeout, the ETK can be configured to increase the DAP timeout value.

  • On / Auto – Detect: The ETK will increase the timeout, if supported by the microcontroller.

  • Off – The ETK will leave the timeout at the default value defined by the microcontroller.
