摘要：Power Train ECU的CPU用的比较多的基本来自于Infineon，ST，FreescaleBOSCH的16位ECUM(E)7系列主要使用C167内核的CPU，早期的M(E)7系列使用西门子半导体(Infineon英飞凌的前身)的C167的，后来ST从西门子引进了C167内核，为BOSCH定制了ST10系列CPU，价格上更有优势，因此之后BOSCH的ECU都基本上采用ST的ST10系列CPU。BOSCH的32位ECUME9系列主要使用PowerPC内核的CPU MPC55系列，那时候还叫Motorola，现在叫Freescale，M(E)9主要在美国市场上销售MED17系列主要使用I
