Understanding System Basis Chips: Key integration for automotive ECUs

An SBC (System Basis Chip) is an integrated component that combines common system features required on Automotive ECUs on a single device. A System Basis Chip automotive solution typically integrates:

  • Communication transceivers (CAN FD, LIN)
  • Voltage regulators (LDO, DC-DC)
  • Diagnostics and supervision functions
  • Switches and wake inputs 

How does an SBC microcontroller interface work?

System Basis Chips connect to the host microcontroller via an SPI, providing power management, communication, and monitoring in one simplified architecture. Infineon SBC support the following resources:

  • Evaluation Boards & Shield for Arduino
  • SBC Config Wizard (Configuration Tool)
  • SBC Microcontroller Library
  • Power Dissipation Tool & Bode Plot
  • CAN PN Configurator
  • Application Notes, User Manuals & Data Sheets, eLearnings for SBC, Lite and MR+
  • FIT Rates & Module/Area Breakdown
