The Freescale MPC5643L 32-bit MCU built on Power Architecture technology reduces design complexity and component count by putting key functional safety features on a single chip. It specifically addresses the ISO 26262 safety standard up to the most stringent ASIL D requirements. Dual-core, dual-issue architecture enables more performance while using less power Lockstep mode provides a software environment for redundant processing and calculations Decoupled parallel mode supports applications needing maximum performance or software diversity Precise and deterministic control timing for real-time applications, such as motor control A SafeAssure functional safety solutionDual e200 Z4 CPU architectureDual processing spheres including; CPU, DMA, interrupt controller, crossbar and MPU for logic level fault detectionTwo statically configurable modes of operation: Lockstep operation (redundant processing and calculations) and dual parallel mode (independant core operation)Fault collection unit, which monitors and manages fault eventsError correction coding on RAM and flash memory allows detection/correction of memory errorsFirst MCU to achieve ISO 26262 functional safety standard certificationRobust communications with FlexRay™ and CAN/safety port high-speed low latency messagingCross-triggering unit coordinates ADC, timer and PWM generation and minimizes CPU interrupt loadeTimer x 3ADC x 2
