System Basis Chips (SBC)
Infineon’s System Basis Chips (SBC) offer high integration and high performance at an optimized system cost for various automotive applications, including but not limited to: Body Control Modules, Gateways, Closure Modules (door, roof, tailgater, trailer), Seat Control Modules, Gear Shifter, Fuel Pumps, HVAC, Wireless In-Cabin Charger, Transfer Case, NOx Sensors and Exhaust Modules, Light Control Modules, Water Pumps. Our solutions combine voltage supplies such as LDO or DC-DC with up to 750mA, communication interfaces with CAN transceiver Flexible Data-Rate up to 5Mbit/s according to ISO 11898-2:2016 (including Partial Networking option) and LIN transceiver (LIN2.2/J2602) as well as supervision features (Wake input, Watchdog, Reset, Interrupt, Fail Output).
Product Selection Tree
An SBC is an integrated component that combines common system features required on Automotive ECUs such as: communication transceivers, voltage regulators, diagnostics and supervision functions, switches and wake inputs.
An SBC can be used in all Automotive ECUs where a communication interface and a supply for the microcontroller is required, for example in:
- Body Control Modules
- Climate Control Modules
- Light Control Units
Our highly integrated System-on-Chip solutions have various substantial benefits through advanced diagnosis features and minimized number of components.
Infineon System Basis Chips:
- Offers high integration and high performance at an optimized system cost for various automotive applications
- Extend battery life with very low quiescent current modes
- Improves the overall system reliability
- Reduced system cost through low component count and small PCB footprint (up to 80% smaller footprint)
- Enables design flexibility and reduces software design effort through shared state machine and SPI access
The new generation of Infineon SBCs offer full Software (SPI registers) and Hardware (package and pin location) compatibility across the families.
Infineon provide large variety of portfolio options from low to high power and scalable communication nodes with minimum 1 CAN FD transceiver as well as up to 4 LIN.
Infineon offers a comprehensive set of support tools to facilitate the design in process including:
- Reference designs
- User manuals
- Basic µC routines

QM-parts in Functional Safety Applications (ASIL)
Infineon’s System Basis Chips are developed as QM-parts, but nonetheless can be and are already used in a variety of application that require Functional Safety (ISO26262) up to ASIL-D such as but not limited to Gear Shifters (ASIL-B), Electric Parking Brake (ASIL-C), ADAS Domain Control (ASIL-D) or Chassis Domain Control (ASIL-D).
Infineon offers the following design-in support for its automotive System Basis Chips (SBC):
- FIT data information (ISO26262)
- Function/Blocks vs. Area Breakdown
