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.
Features
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
This product is included in Freescale’s product longevity program, with assured supply for a minimum of 15 years after launch
