Challenge
The customer was developing a BMS for a new electric vehicle platform and needed an MCU that could handle complex battery monitoring algorithms while meeting ASIL-D functional safety requirements. Their initial MCU choice lacked hardware safety features, requiring extensive software-based safety mechanisms that consumed significant processing resources.
Solution
We recommended the AURIX TC399XX with its six TriCore processors and dedicated safety cores. The integrated HSM provided secure key storage for cryptographic functions, while the lockstep cores enabled ASIL-D compliance with minimal software overhead. We also provided reference code for BMS applications.
Results
The customer successfully achieved ASIL-D certification on their first submission, saving an estimated 6 months in development time. The hardware-based safety features reduced software complexity by 40%, and the system achieved excellent battery monitoring accuracy of ±5mV per cell.
