ETK – ECU Interface

Independently of its connection with the microcontroller, an ETK provides development and calibration tools with a powerful interface to the development ECU. Thanks to their rugged design on both the mechanical and electrical side, ETKs are fully vehicle-compatible. Operating reliably on voltages between 4.3 V and 18 V, they also tolerate short-term voltage drops. Due to their extremely compact design, ETKs can be accommodated inside the housings of production ECUs. They are impervious to the temperature extremes of winter testing and hot-weather trials at the ECU's real-life working location in the vehicle. Without requiring intermediate amplification, the ETK interface enables interference-free, high-bandwidth Ethernet data transmission at 100 Mbit/s over distances of up to 30 meters.

Benefits

• Available for the most common 8 bit, 16 bit and 32 bit micro-controllers, with or without multiplexed bus
• Small dimensions facilitate mounting of ETKs within the ECU housing
• Requires only minor modifications to the hardware and only minimum supplement to the code of the production ECU
• Extensive mechanical adaptation options (Flash or microcontroller adapter)
• Robust design withstands strong vibrations
• Extended operation temperature range from typically -40 °F to 230 °F (-40 °C to 110 °C)
• External or ECU-controlled power supply without load to the ECU power supply
• Wide power supply range from 4.3 V to 18 V (can be extended with external power supply modules from 6.5 V to 36 V)
• Tolerance to voltage spikes and voltage dips
• Power-on and voltage monitoring with safety reload from flash
