Freescale公司的MC33903/4/5是第二代的系统基础芯片(SBC),能作为MCU的先进电源管理,并集成了几种先进的集成电路传感器CAN收发器,内置了增强高速CAN接口(ISO11898-2和-5),以及本地和总线故障诊断,保护与故障安全操作模式.主要用在航空和水下系统,汽车和机器人系统,农场设备,灯和电感负载控制,DC马达控制,工业激励控制等.本文介绍了MC33903/4/5系列产品主要特性,框图和简化应用框图,评估板KIT33905D5EKEVBE主要特性,建立框图,电路图,材料清单和PCB元件布局图和走线图.

The 33903/4/5 is the second generation family of the System Basis Chip (SBC). It combines several features and enhances present module designs. The device works as an advanced power management unit for the MCU with additional integrated circuits such as sensors and CAN transceivers. It has a built-in enhanced high-speed CAN interface (ISO11898-2 and -5) with local and bus failure diagnostics, protection, and fail-safe operation modes. The SBC may include zero, one or two LIN 2.1 interfaces with LIN output pin switches. It includes up to four wake-up input pins that can also be configured as output drivers for flexibility. This device is powered by SMARTMOS technology.

This device implements multiple Low-power (LP) modes, with very low-current consumption. In addition, the device is part of a family concept where pin compatibility adds versatility to module design.

The 33903/4/5 also implements a..
