System basis chip
A system basis chip is an integrated circuit that includes various functions of automotive electronic control units on a single die.
It typically includes a mixture between digital standard functionality like communication bus interfaces and analog or power functionality, denoted as smart power. Therefore, SBCs are based on special smart power technology platforms.
The embedded functions may include:
- Voltage regulators
- Supervision functions
- Reset generators,
- Watchdog functions
- Bus interfaces, like Local Interconnect Network, CAN bus
- Wake-up logic
- Power switches
Various major automotive semiconductor manufacturers offer SBCs.
