How automotive transceivers enable modern in-vehicle communication

Modern vehicles rely on a layered network of bus systems to exchange data between electronic control units (ECUs). An automotive transceiver acts as the interface between the digital logic of a microcontroller and the physical bus line, translating signals for reliable transmission across the vehicle's electrical environment.

Infineon's transceiver portfolio covers every major automotive bus protocol: CAN (Controller Area Network), CAN FD (Flexible Data-rate), CAN FD SIC (Signal Improvement Capability), and LIN (Local Interconnect Network). Together, these cover data rates from 20 kbps over LIN up to 8 Mbps over CAN FD SIC, enabling architects to select the right transceiver for automotive ECUs in every domain — from low-bandwidth body and comfort functions to high-speed powertrain and ADAS networks.

All devices are AEC-Q100 qualified and operate across -40 C to +150 C ambient temperature.

CAN FD and CAN FD SIC for high-speed, high-integrity vehicle networks

CAN is the dominant medium-speed bus for powertrain, chassis, and ADAS ECUs. Infineon's automotive transceiver portfolio for CAN covers classical CAN (up to 1 Mbps), CAN FD (up to 5 Mbps), and CAN FD SIC (up to 8 Mbps). CAN FD SIC actively shapes bus signals to suppress ringing caused by unterminated stubs in large, complex network topologies. Engineers maintain robust communications at high bit rates without redesigning the physical layer or upgrading cabling. For partial networking (PN) applications, Infineon offers CAN PN transceivers with the lowest quiescent current in the market, directly reducing CO2 emissions at vehicle level.

Key parameters:

  • Data rates: 500 kbps to 8 Mbps
  • Supply: 3.3 V and 5 V variants
  • ESD robustness: exceeds ISO 10605 and IEC 61000-4-2
  • Worldwide OEM approval; pin-to-pin compatible with leading competitor devices
  • Operating temperature: -40 C to +150 C (Endurance CAN family)

Low-cost, single-wire LIN transceivers for body and comfort ECUs

LIN is the standard low-speed bus for body, interior, and comfort applications — seat control, climate, lighting, and door modules — where bandwidth requirements are low and cost is critical. Operating on a single wire at up to 20 kbps, it complements CAN in every modern vehicle architecture. Infineon's modular LIN lineup ranges from high-end to basic single-channel transceivers, with integrated variants including dual-LIN and LIN-LDO combinations. This makes the portfolio well suited for transceiver for automotive ECUs that require compact integration and reduced BOM count.

Key parameters:

  • Compliant with LIN 2.x and SAE J2602
  • Top EMC performance and very high ESD robustness
  • Available in DSO-14 and TSON-14 packages
  • Pin-out compatible with competing devices, reducing re-qualification effort
  • Low quiescent current for efficient standby operation

The LIN bus connects sensors, actuators, and switches to a master ECU over a simple single-wire interface, reducing wiring harness complexity and design cost for vehicle manufacturers.

How Infineon automotive transceivers exceed ESD and EMC standards

Automotive bus lines face harsh electromagnetic environments: load dump transients, conducted emissions from adjacent modules, and ESD events during assembly and operation. Transceivers sit directly on these bus lines, making ESD and EMC performance critical.

Every Infineon automotive transceiver is designed to meet or exceed:

  • ESD robustness per IEC 61000-4-2 and ISO 10605 (HBM up to 8 kV on bus pins)
  • Conducted and radiated emissions per CISPR 25 Class 5
  • Immunity per ISO 11452 and IEC 62132

CAN FD SIC technology reduces ringing artefacts on long, stub-heavy bus topologies, improving signal integrity at 2-8 Mbps without additional filtering components. CXPI devices achieve low EME through pseudo sine-wave shaping, reducing PCB design effort for emission compliance.

LIN and CAN transceivers carry worldwide OEM approval, confirming EMC qualification against major vehicle manufacturer requirements across global markets.

For engineers evaluating EMC in their ECU design, Infineon's longevity program provides information on long-term product availability.

CAN, LIN or CXPI: selecting the right automotive bus protocol

Choosing the right automotive transceiver protocol depends on data rate, network size, cost target, and application domain. Key decision factors per protocol:

CAN / CAN FD / CAN FD SIC

  • Domains: powertrain, chassis, ADAS, gateway ECUs
  • Speed: 500 kbps to 8 Mbps
  • Topology: differential two-wire bus, up to ~110 nodes
  • Standard: ISO 11898-2 / ISO 11898-5 / ISO 11898-6

LIN

  • Domains: body, interior, seat, climate, lighting
  • Speed: up to 20 kbps
  • Topology: single-wire bus, 1 master + up to 16 slaves
  • Standard: LIN 2.x, SAE J2602

In most architectures, CAN handles error-sensitive, time-critical data on a 5 V differential bus, while LIN manages lower-priority functions on a 12 V single-wire bus. This layered approach balances cost, bandwidth, and complexity across domains.

AEC-Q100 qualification and long-term supply for automotive ECUs

Automotive ECU programs run for 10-15 years in production, followed by a similar aftermarket period. Component availability and consistent quality over that lifecycle are as important as initial technical performance.

All Infineon automotive transceivers are:

  • AEC-Q100 qualified (Grade 0 or Grade 1 depending on temperature class)
  • Covered by Infineon's Smart Power Longevity Program with documented long-term availability commitments
  • Supported with PPAP and IMDS documentation for OEM qualification

The Endurance CAN family supports -40 C to +150 C ambient temperature, meeting requirements for under-hood and close-to-engine ECU placements. Infineon's dependability framework combines automotive quality, functional safety (ISO 26262), and cybersecurity into a single supply commitment, reducing qualification effort for tier 1 engineers across multiple vehicle platforms.

Design-in tools and resources for automotive transceiver ECUs

Integrating a transceiver for automotive ECUs requires more than selecting the right IC. Infineon provides design resources to accelerate development and reduce risk:

  • Datasheets and application notes covering bus termination, EMC layout guidelines, and partial networking configuration for CAN PN devices
  • Reference schematics for typical CAN and LIN ECU interfaces
  • Pin-to-pin compatible drop-in replacements for major competitor devices, minimising re-qualification when migrating designs
