System basis chip
A System Basis Chip (SBC) is an integrated circuit that includes various functions of automotive electronic control units (ECU) on a single die.[1][2]
It may comprise the following or other functions:
- Voltage regulators
- Supervision functions
- Reset generators,
- Watchdog functions
- Bus interfaces, like LIN, CAN or others
- Wake-up logic
- Power switches
The complexity range for SBCs starts with rather simple hardwired devices to configurable state-machine controlled devices, e.g. through a serial peripheral interface.
Various major automotive semiconductor manufacturers offer SBCs.
