MC33907

Roll over image to zoom in

The NXP^® MC33907 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 reduces software complexity with dual-core lock-step MCUs
