Does TC397XA256F300SBCKXUMA1 include hardware cryptographic acceleration?
Yes, TC397XA256F300SBCKXUMA1 integrates a dedicated cryptographic co-processor supporting AES-128/256 encryption/decryption, SHA-256 hashing, and true random number generation (TRNG). These functions operate independently of the main CPU cores and are accessible via protected memory-mapped registers with key isolation.
What is the maximum supported CAN FD data rate on this MCU?
The TC397XA256F300SBCKXUMA1 supports CAN FD up to 5 Mbps in the data phase, compliant with ISO 11898-1:2015. Both CAN FD controllers feature programmable bit timing, flexible data length (up to 64 bytes), and built-in message filtering with hardware FIFOs for deterministic interrupt latency in high-throughput vehicle networks.
Is TC397XA256F300SBCKXUMA1 pin-compatible with other AURIX™ TC3xx devices?
No, TC397XA256F300SBCKXUMA1 uses a unique 176-pin LQFP package layout optimized for its specific peripheral set and thermal profile. Pin compatibility is limited to same-package variants within the TC397X subfamily (e.g., TC397XP), but not across TC37x or TC38x families due to differing peripheral mappings and safety architecture implementations.
