About

Scalable automotive telematics control unit solutions

The scalable chip-set solutions provided by Infineon support the ever-changing specifications for automotive telematics control units (TCU). A scalable solution makes it possible to create core designs that are flexible and cost-effective while cutting down on development expenses and time to market. Check out the benefits of Infineon's car chip-set solutions below.

Scalability: Scalable family solutions with wide compatibilities on both hardware and software support designs from low- to high-end systems with less design effort.

Performance: Best-in-class performance (microcontrollers, microphones, power supply, etc.) and robust broadband connectivity (Wi-Fi and Bluetooth®) improve customer experience significantly.

Security: Secured MCUs, secured memories, and secured connectivity support secured firmware updates over-the-air (FOTA), and safeguard consumers from cyber-attacks.

Total cost of ownership: Broad portfolio provides one-stop shop on both commercial and technical levels which significantly reduces purchase costs as well as system design effort.

Infineon's TCU solutions enable complete OTA end-to-end protection

With constantly increasing software scopes and comparatively short development times, the possibility for software updates over-the-air (SOTA/OTA or FOTA) is indispensable for future vehicle generations. The OTA capability allows the seamless installation of new features or feature upgrades while reacting swiftly to potential security attacks. Thus, OTA increases customer satisfaction, reduces costs and recalls, and has the potential to open new revenue streams for the OEMs.

Infineon's solutions enable complete end-to-end protection while helping to minimize vehicle unavailability.

These solutions include:

  • Discrete security IC to enhance platform security and protect cellular connectivity (OPTIGA™ TPM SLI 9670 and SLx family)
  • TRAVEO™ T2G or AURIX™ microcontrollers to manage the OTA update in-vehicle network (from source to sink) and to maximize the vehicle availability (incl. dual bank flash to allow for A/B SWAP and EVITA HSM Full)
  • External memory to store large SW images (SEMPER™ NOR flash)
  • Last but not least, AIROC™ automotive wireless offers a cost-effective alternative for bulk updates

AIROC™ Wi-Fi and Bluetooth® solutions for robust connectivity

Infineon is leading in real simultaneous dual-band (RSDB) solutions providing simultaneous operation in both 2.4 GHz and 5 GHz bands, as well as multiple-input multiple-output (MIMO) support. RSDB solutions provide the necessary bandwidth and the software architecture required to support complex use-case scenarios for cars, enabling combinations of AP, station, and P2P connections simultaneously.

Recommended memories for automotive connectivity systems

Infineon's parallel NOR flash devices and serial NOR flash devices feature automotive-proven MIRRORBIT™ technology to ensure data reliability and the high endurance required for frequent writes over the product lifespan. In addition, they provide fast system boot times and different densities to scale platforms. Infineon’s NOR flash solutions are AEC-Q100 grade 1 to 3 qualified to meet automotive standards for a wide operating temperature range.

Infineon's automotive F-RAM has no write delays and data is immediately non-volatile. F-RAM offers a virtually unlimited endurance of 100 trillion read/write cycles. This enables much more compact and robust designs compared to conventional EEPROM solutions.

Infineon’s HYPERRAM™ 2.0 is a high-speed, low-pin-count, self-refresh dynamic RAM (DRAM) for high-performance embedded systems requiring expansion memory. HYPERRAM™ 2.0 offers HYPERBUS™ and Octal SPI interfaces that draw upon the legacy features of both parallel and serial interface memories while enhancing system performance and ease of design, as well as reducing system cost.

Infineon enables automotive security system solutions

As the complexity of systems in cars increases, so does the volume of data to be processed and distributed. New payment methods, such as parking fees or road tolls, require a secure flow of transaction data. Infineon can draw on years of expertise in chip card and identification systems to propel automotive data security to the next level. The broad portfolio of automotive security solutions includes microcontrollers with an embedded hardware security module (HSM), secured NOR flash and discrete security controllers. 

BRIGHTLANE™ Ethernet portfolio for telematic control units

Infineon's BRIGHTLANE™ Ethernet portfolio plays a vital role in supporting telematic control units (TCUs) by delivering high-speed, reliable, and secure connectivity for modern connected vehicles. Ethernet PHYs and switches ensure seamless integration with TCUs, providing high-bandwidth connections (e. g., 100BASE-T1 and 1000BASE-T1) to manage data-intensive applications such as infotainment, navigation updates, and fleet management. The portfolio's Time-Sensitive Networking (TSN) capabilities enable real-time communication and synchronization essential for safety-critical systems, while integrated security features such as MACsec protect sensitive data against cyber threats. By offering scalable, multi-Gbit solutions with robust reliability, Infineon’s BRIGHTLANE™ Ethernet portfolio empowers TCUs to support the connected car ecosystem, ensuring efficient, secure, and future-ready telematics solutions tailored for next-generation vehicles.
