The ECU family consists of four products with different configuration levels. The products comply with ASIL-C as specified ISO 26262, the international standard for automotive functional safety. Furthermore, a robust aluminum housing suited for harsh environments protects the IP68-rated device. Optionally, an IP6K9K housing is available. The product provides Autosar-compatible software architecture. It is based on a 32-bit dual-core processor and features a 128-KiB internal RAM, a 1-MiB flash memory as well as a 32-KiB external EEPROM. The MCU is clocked with 160 MHz.

Besides the CAN and LIN interfaces, the ECU comes with up to 89 analog and digital I/O channels. This includes functional safe PWM outputs. Weber-Hydraulics uses the product for electro-hydraulic applications. The product is intended for mobile machines including agriculture and construction vehicles. Optionally, the ECU comes with a 3D accelerator. Sensor voltage output is available at the device’s 154-pin connector.
