AURIX (Automotive Realtime Integrated Next Generation Architecture) is a 32-bit Infineon microcontroller family, targeting the——automotive industry. It is based on multicore architecture of up to three independent 32-bit TriCore CPU's.

Applications※

The AURIX series has been used in some artificial intelligence applications, in electric vehicles, and in the navigation systems of self-driving cars.

Technical features※

System performance※

The AURIX family devices range from a 300 MHz three-core device with 8MB embedded Flash down to 130 MHz and 80 MHz single-core and "single core lockstep devices with 1."5MB, "1MB and 0."5MB of embedded Flash. The package portfolio includes a BGA-516 package with a ball-compatible BGA-292 package (I/O subset), and compatible QFP-176, "QFP-144," QFP‑100 to QFP-64 packages.

TRICOR DSP functionality※

• Multicore
• TriCore with up to 300 MHz per core
• 1.7–2.4 DMIPS/MHz
• DSP with up to 1.8 GFLOPS
• Supports floating point and fixed point operations with all cores
• Fast Fourier accelerator
• Pixel Preprocessor
• Embedded EEPROM
• Generic Timer Module (GTM)
• Advanced timer unit for totally flexible PWM generation and hardware input capture
• Redundant flexible 12-bit ADC
• Delta sigma converters
• Single supply 5V. Or 3.3V
• Availability of AUTOSAR 4.x and 3.2.1
• Ta = -40 °C ... 145 °C

Safety Features※

The AURIX architecture has been developed according to an audited ISO26262-compliant process and designed to meet ASIL-D on an application level. The platform uses up to 2 cores in TriCore lockstep mode, a lockstep architecture combined with safety technology such as internal communication buses/distributed memory protection systems. Hardware level encapsulation techniques allow integration of software with various safety levels (QM to ASIL-D) from different sources, reducing the "system complexity of implementing those safety levels."

The AURIX architecture offers the following features:

• Hardware-focused safety concepts for reduced SW overhead
• Lockstep with clock delay
• Access permission system
• Safety management unit
• Safe DMA
• I/O, clock and voltage monitors
• Safety Software for checking the functionality of the core
• ISO 26262 conformance to support safety requirements up to ASIL-D

Security Features※

Infineon has integrated a programmable Hardware Security Module (HSM) into the AURIX family in line with EVITA (E-safety vehicle intrusion protected applications). This “embedded chipcard” protects against IP infringement, fraud and software hijacking.

• Hardware Security Module (HSM)
• Secure software updates, Secure Boot, Secure Key Update, Secure Communication
• Immobilizer
• Tuning protection
• Mileage protection
• Component protection
• IP protection

Scalability※

• From Single Core to Triple Lockstep Core
• 80–300 MHz
• 256KB – 8MB Flash
• 48KB – 2.7MB SRAM
• ASIL Level from QM up to ASIL D
• HOT Package Option

Connectivity※

• Ethernet 100Mbit
• FlexRay
• High-Speed Serial Link IF
• SPI, CAN (FD), LIN, UART
• Hardware SENT interface for low CPU load
• Camera Interface (up to 16-bit)
• External ADC IF (up to 16-bit)
• External Bus Interface for Memory Extension

Supply security※

Infineon has set up dual-fab manufacturing using two local separated Frontend production sites. Both sites are using identical certified processes and tooling. All products from both sides will be AEC-Q100 qualified and are manufactured in a 65 nm technology.Infineon has officially stated that the embedded flash technology for TC39xXX utilizes a 40 nm manufacturing process.

Tools and software※

Infineon has several full-featured evaluation boards for their TriCore product line. Development tools for evaluation such as compilers, debuggers and AURIX Development Studio IDE are included, as well as technical documentation: user manuals, architecture manuals, application notes, data sheets, board documentation.
