Infineon AURIX

Infineon AURIX is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Infineon AURIX rather than just read about it. In short: 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 CPUs.

Key takeaways

Infineon AURIX belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Infineon AURIX to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Infineon AURIX from memory before moving on to harder problems.

Reference excerpt

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 CPUs.

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.

TriCore 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 or 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.

Worked examples

Example 1 — a first encounter with Infineon AURIX

Start with the simplest possible case. Write down what Infineon AURIX claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Infineon AURIX before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Infineon AURIX ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Infineon AURIX

In research: Infineon AURIX appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Infineon AURIX in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Infineon AURIX is common in secondary-school and first-year university syllabi. It links to neighbouring topics Microcontrollers, so understanding it makes those chapters shorter.
In everyday life: Look for Infineon AURIX outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
