Safe Assure® (Functional Safety)
When it comes to functional safety, NXP stands for quality and reliability. Our SafeAssure program simplifies system-level safety requirements in accordance with ISO 26262.
Safe System Basis Chip with Buck and Boost DC/DC up to 1.5 A on Vcore
The NXP® MC33908 system basis chip (SBC) provides power to MCUs and optimizes energy consumption through DC/DC switching regulators, linear regulators and ultra-low-power saving modes. Featuring:
- Advanced functional safety measures
- A serial peripheral interface (SPI) to allow control and diagnostics with the MCU
- Integration of CAN and LIN physical interfaces compliant with the ISO 11898-2,-5, LIN 2.2, 2.1/J2602-2 standards along with the latest automotive OEM standards for EMC and ESD
- A range of integrated safety features such as monitoring of critical analog parameters, a failsafe state machine and an advanced watchdog reduce software complexity with dual-core lock-step MCUs
