MC33908NAE数据手册恩XP中文资料规格书

描述 Description

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
