TTC 2300 Family

The TTC 2300 ECUs are equipped with the second generation of the high performance AurixTM TriCoreTM CPU. With up to six cores, each running at 300 MHz, the TTC 2300 family is the right choice for future vehicles. To fulfill the highest security standards, the CPU is equipped with a dedicated Hardware Security Module.

The TTC 2300 family supports advanced data configuration, logging and storing. It comes with up to 6.47 MB internal SRAM and 16 MB internal Flash as well as an external Flash memory of up to 32 MB. In addition, it is also equipped with EEPROM or FRAM memory extensions.

In addition to the Flash option, the controller family supports efficient memory management and data transfer with a user-friendly file system available for all TTC 2300 ECU variants.

The TTC 2300 variants are equipped with up to 60 inputs and outputs (I/O). The I/Os are highly configurable and can be flexibly configured for different types of sensors and actuators, which helps to save time and development costs. Analog and digital timer inputs, both high-side and low-side PWM outputs, as well as PVG control outputs, make the TTC 2300 ECUs the perfect match for a variety of applications.

The controllers are designed for a total load current of up to 45A and high inrush currents.

More automation and assistance systems go hand-in-hand with an increasing number of sensors, and these sensors are getting smarter. The TTC 2300’s modern communication interfaces address the requirements of electronic architectures in tomorrow’s smart vehicles. The TTC 2300 ECU product family has four CAN-FD interfaces with up to two Mbit/s. One CAN channel can be used as wake-up source.

In addition, the control units are equipped with two high-speed data (HSD) connectors for Ethernet and BroadR-Reach communication. These provide the necessary bandwidth for the increasing number of sensor and actuator data in vehicles. Up to four SENT interfaces, including the Short PWM Code (SPC) enhancement, are available.

TUeV Nord safety certified the TTC 2300 family for an extended set of functional safety standards, helping to reduce overall vehicle certification costs: AgPL d for agricultural machinery (ISO 25119); MPL d for earth-moving machinery (ISO 19014); ASIL C for cars, trucks, and buses (ISO 26262); as well as SIL 2 and PL d for machinery (IEC 61508 / EN ISO 13849).

The mixed criticality concept allows both safety-related and non-safety-related code to be executed on the same CPU without reducing the overall safety level (freedom from interference), which helps to significantly reduce time–to-market.

The TTC 2300 product family is delivered with the safety-certified, real-time operating system PXROS. It enables full use of the AurixTM multicore architecture by freely distributing tasks to the different CPU cores. The ECUs can either be programmed in a C/C++ or with CODESYS Safety SIL 2, including support for CANopen Safety Master.

The powerful MATCH toolchain by HYDAC is optionally available and provides enhanced functionality for testing and service in the field.

The TTC 2300 electronic control family answers the rapidly growing industry trend of electrification. For the TTC 2300 family, the possibility of controlling electric motors was considered from the start. The H-Bridge interface supports frequencies up to 1 kHz and currents up to 4A.
