Reliable solutions for entry-level and high-end airbag systems

Infineon provides flexible semiconductor solutions for both entry-level and high-end airbag control unit systems that meet the ASIL-D requirements. Likewise, you can rely on our comprehensive system expertise for all airbag-related questions. And since Infineon supplies all components from one single source, you can rest assured that your automotive airbag applications will always function reliably.

Wide range of benefits including improved safety and performance
  • Airbag systems are standard in most cars and mandatory in many countries.
  • Infineon’s broad product portfolio supports scalability and flexibility for building systems from four to over twenty firing loops.
  • Full range of airbag ASSPs from pressure sensors for side impact detection to driver and transceiver ICs.
  • High-performance 32-bit AURIX™ MCU family with dedicated safety features enables the integration of multiple functions.
  • The components are optimized in terms of both system interoperability and the best price-performance ratio.
  • These systems are mandatory in order to achieve the highest possible scores in the various “New Car Assessment Programs” (NCAP) around the world.

Datalogging challenges in traditional event data recorders

  • Temporary RAM buffer to hold an event data record. More data means more internal RAM.
  • Event-based trigger to address endurance limit. Data is logged in non-volatile memory after the event using back-up power.
  • Higher back-up capacitor for larger data

Infineon solution

  • Fast write and instant non-volatile F-RAM memory enables continuous data logging
  • Infinite endurance eliminates the need for a temporary RAM buffer
  • Continuous logging means event records are non-volatile even before the event is triggered

F-RAM for automotive markets offers fast writes at full interface speed. F-RAM has no write delays and data is immediately non-volatile. Traditional non-volatile memories have delays of five or more milliseconds before data becomes non-volatile. In the event of a power failure, pending data is lost unless the system has extra capacitance or batteries to keep the system running until data is saved.
