Safety-certification and mixed-criticality

The TTC 2030 family is safety-certified according to various safety standards:

  • SIL 2 and PL d certified for machinery (IEC 61508 / EN ISO 13849)
  • for the agricultural market according to AgPL d (ISO 25119)
  • for earth-moving machinery according to MPL d (ISO 19014)
  • ASIL C certified for cars, trucks, and buses (ISO 26262).

The products are certified by TÜV Nord. The mixed criticality concept of the TTC 2030 family, also known as freedom from interference, allows both safety-related and non-safety-related code to be executed on the same AurixTM CPU without reducing the overall safety level. This leads to significantly reduced time–to-market of mobile machinery.

Highly configurable inputs and outputs

The TTC 2030 variants are equipped with up to 32 inputs and outputs (I/O). The I/Os are highly configurable for different types of sensors and actuators. This makes the TTC 2030 product family the perfect fit for compact applications. Part of the I/O set are analog and digital timer inputs, both high-side and low-side PWM outputs, as well as PVG control outputs. The controllers are designed for a total load current of up to 24A and high inrush currents.

Large set of interfaces for future proof vehicle architectures

The TTC 2030’s modern communication interfaces address the enhancing requirements of electronic architectures in tomorrow’s smart off-highway vehicles. For connection of smart sensors, up to four SENT interfaces, including the Short PWM Code (SPC) enhancement, are available. The TTC 2030 ECU product family is furthermore equipped with a LIN interface and two CAN-FD interfaces with up to two Mbit/s. One CAN channel can be used as wake-up source. In cases of agricultural use, an ISOBUS compliant CAN bus is available.

Operating system and efficient programming

Part of the software package delivered with the TTC 2030 is the real-time operating system PXROS, which is also safety certified. It enables free distribution of tasks between the two CPU cores for efficient application programming. By sharing modularity with the TTC 2000 series software blocks can be reused between different ECU families. The TTC 2038 can either be programmed in a C/C++ environment or in the future also with CODESYS Safety SIL 2.
The powerful MATCH toolchain by HYDAC is optionally available and provides enhanced functionality for testing and service in the field.
