Freescale MC33905 MCU功率管理解决方案

Freescale 公司的MC33905是第二代系统基本芯片(SBC),包括有多中特性和增强的模块设计,能作为MCU和其它集成电路如传感器,CAN收发器的先进的功率管理单元. MC33905内置了高速CAN接口(ISO11898-2 和-5),以及本地和总线故障诊断,保护以及故障安全操作模式等.本文介绍了MC33905主要特性,方框图,以及简化应用框图和典型应用电路, MC33905评估板EVB主要特性, 电路图和材料清单(BOM).

The 33904/5 is the second generation family of System Basis Chips which combine several features and enhance present module designs. The device works as an advanced power management unit for the MCU and additional integrated circuits such as sensors, 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 mode. The SBC may include one or two LIN 2.1 interfaces with LIN output pin switches. It includes up to 4 wake-up input pins than can also be configured as output drivers for flexibility.

This device implements multiple Low Power modes, with very low-current consumption. In addition, the device is part of a family concept where pin compatibility, among the various devices with and without LIN interfaces, add versatility to module design.
