ECU interfaces: ETK / FETK / XETK

Powerful ECU measuring and calibration access

The ETAS Ethernet-based ECU interfaces ETK, FETK, and XETK provide direct access to the measurement variables and control parameters of an ECU. Access is enabled via the parallel data and address bus, or via a serial microcontroller testing or debugging interface. Their extremely compact design allows to accommodate ETKs, FETKs, and XETKs inside the housings of production ECUs, ensuring utmost interface protection.

Parallel operations

Simultaneous access to the ECU for measurement, calibration, and rapid prototyping tools.

Dedicated power supply

Enables the preparation and initiation of cold-start testing independently of the ECU.

Parallel and serial ECU interface

The data exchange between ETK, FETK, XETK and microcontroller uses a mailbox as intermediate memory for measurements and real-time applications. When the microcontroller does not provide an external data and address bus, a microcontroller variant containing extended memory is often used for ECU development. In both test bench and in-vehicle testing, the interfaces facilitate access to the microcontroller over a long distance through a powerful test, debug, or trace interface.

Extremely robust

ETK, FETK, and XETK interfaces are mechanically and electrically robust. They resist temperature extremes and vibrations at the ECU’s location in the vehicle.

Reducing computing overhead in ECUs

Reducing computing overhead in ECUs

ETK, FETK, and XETK interfaces call for very little computing overhead on the part of the ECU. On engine ECUs, for example, large numbers of measured values can be acquired easily without impact on ECU overhead, even at high engine speeds that impact computing power. Using an ETK, FETK, or XETK development ECU, series-production software can be readily calibrated and verified with the production ECU. This helps minimize driver changes in the platform software.

Supported microcontrollers

ETAS provides a broad portfolio of ETKs, FETKs, and XETKs for commonly used microcontrollers for engine and transmission ECUs from NXP, Infineon, Renesas, Texas Instruments and STMicroelectronics. ETKs, FETKs, and XETKs are designed according to customer requirements, for example regarding memory sizes and mechanical integration with the ECU.
