Freescale Qorivva MPC5643L汽车安全解决方案

Freescale公司的Qorivva MPC5643L是基于Power架构的32位MCU,设计满足最严格要求的ASIL D级规范,是首个达到ISO 26262安全标准的MCU. MPC5643L是系统级芯片(SoC),采用高性能的e200z4d双核和32位Power架构技术,核频率120MHz,主要应用在汽车电子,马达控制,工业和过程控制.本文介绍了MPC5643L主要特性,框图,以及TRK-USB-MPC5643L汽车安全开发套件主要特性和电路图.
The Qorivva MPC5643L 32-bit MCU built on Power Architecture® technology is designed to specifically address the ISO 26262 safety standard up to the requirements of the most stringent ASIL D level. The MPC5643L is the first MCU to achieve ISO 26262 functional safety standard certification. It reduces design complexity and component count by putting key functional safety features on a single chip with a dual-core, dual-issue architecture, which can be statically switched between lockstep mode (redundant processing and calculations) to decoupled parallel mode (independent core operation). The Qorivva MPC5643L MCU is a SafeAssure functional safety solution.
The MPC5643L series microcontrollers are system-on-chip devices that are built on Power Architecture technology and contain enhancements that improve the architecture’s fit in embedded applications, include additional instruction support for digital signal processing (DSP) and integrate technologies such as an enhanced time processor unit, enhanced queued analog-to-digital converter, Controller Area Network, and an enhanced modular input-output system.
The MPC5643L family of 32-bit microcontrollers is the latest achievement in integrated automotive application controllers. It belongs to an expanding range of automotive-focused products designed to address electrical hydraulic power steering (EHPS), electric power steering (EPS) and airbag applications. The advanced and cost-efficient host processor core of the MPC5643L automotive controller family complies with the Power Architecture embedded category. It operates at speeds as high as 120 MHz and offers high-performance pr...
