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 solution
Dual e200 Z4 CPU architecture
Dual processing spheres including; CPU, DMA, interrupt controller, crossbar and MPU for logic level fault detection
Two 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 events
Error correction coding on RAM and flash memory allows detection/correction of memory errors
First MCU to achieve ISO 26262 functional safety standard certification
Robust communications with FlexRay™ and CAN/safety port high-speed low latency messaging
Cross-triggering unit coordinates ADC, timer and PWM generation and minimizes CPU interrupt load
eTimer x 3
ADC x 2
