About

AURIX™ TC3x features and peripherals

Accelerate system performance with the AURIX™ TC3x family of microcontrollers with multiple cores of TriCore™ architecture, program and data memories, buses, bus arbitration, interrupt system, DMA controller, and a powerful set of on-chip peripherals. Trusted by automotive engineers, the AURIX™ TC3x platform is designed to meet the most demanding embedded control system applications where the competing issues of price/performance, real-time responsiveness, computational power, data bandwidth, and power consumption are key design elements.

The AURIX™ TC3x family is pin-compatible with the AURIX™ TC2x family and offers increased flash memory sizes (up to 16 MB), integrated RAM (over 6 MB), and up to six TriCore™ 1.62 embedded cores, each with a full clock frequency of 300 MHz. New features include a new radar processing subsystem with up to two dedicated Signal Processing Units (SPU), Gigabit Ethernet, additional CAN FD and LIN interfaces, and an eMMC interface for external flash. The family offers several versatile on-chip peripheral units such as serial controllers, timer units, and ADCs to ensure the right solution for your design.

OPTIREG™ PMIC
Ideal for safety-critical automotive applications

The latest AURIX™ TC3x 32-bit MCUs are well-suited for safety-critical applications to support clean, autonomous, and connected cars. Ranging from classic airbags, braking, and power steering to fail-operational systems supported by sensor-based systems using radar, LIDAR, or camera technologies.

The implemented connectivity features, in combination with the highest level of security, allow for the design of connected cars with applications such as a telematics unit, connected gateway, or in-vehicle wireless charging for portable devices. To make the car clean, the new AURIX™- TC3x second-generation MCUs are well-suited for new systems in electrical and hybrid drives – specifically hybrid domain control, inverter control, battery management, onboard charger, and DC-DC converters, in addition to engine management and transmission control systems.

AURIX™ TC3x combines performance with a powerful safety architecture and offers enhanced security with the second-generation HSM with asymmetric cryptography accelerators and Full EVITA support which makes the family the ideal fit for domain control and data fusion applications.

TriCore™ architecture overview and key features

TriCore™ is the first unified, multi-core, 32-bit microcontroller-DSP architecture optimized for real-time embedded systems. TriCore™ Instruction Set Architecture (ISA) combines the real-time capability of a microcontroller, computational power of a DSP, and high performance/price features of a RISC load or store architecture in a compact re-programmable core.

The architecture supports both 16-bit and 32-bit instruction formats.

The key features of the TriCore™ ISA are:

  • 32-bit architecture
  • 4 GB of address space
  • 16-/32-bit instructions for reduced code size
  • Branch instructions (using branch prediction)
  • Low interrupt latency with fast automatic context switch using wide pathway to 
  • on-chip memory
  • Zero overhead loop capabilities
  • Dual, single-clock-cycle, 16x 16-bit multiply-accumulate unit (with optional saturation)
  • Optional Floating-Point Unit (FPU) and Memory Management Unit (MMU)
  • Extensive bit-handling capabilities
  • Single Instruction Multiple Data (SIMD) packed data operations (2x 16-bit or 4x 8-bit operands)
  • Flexible interrupt prioritization scheme
  • Byte and bit addressing
  • Memory protection and debug support
