FAQ
What is the maximum operating temperature range for TC399XX256F300SBCKXUMA1?
The TC399XX256F300SBCKXUMA1 is qualified for operation from −40 °C to +125 °C ambient temperature, meeting AEC-Q100 Grade 1 requirements for under-hood automotive applications. Thermal design must account for junction temperature limits of 150 °C under full CPU and peripheral load with specified airflow and PCB copper area.
Does TC399XX256F300SBCKXUMA1 support secure boot with public-key verification?
Yes. The device implements secure boot using an immutable Boot ROM that validates ECDSA-signed application images stored in Flash. Public keys are provisioned during manufacturing and cannot be modified in the field. Signature verification occurs before any user code executes, ensuring chain-of-trust integrity.
How many independent CAN FD interfaces does TC399XX256F300SBCKXUMA1 support?
TC399XX256F300SBCKXUMA1 integrates eight fully independent CAN FD controllers, each with dedicated message RAM and configurable bit rates up to 5 Mbps. All channels support ISO 11898-1:2015 compliance, flexible data-length coding, and hardware-based error confinement.
Is the Ethernet MAC capable of IEEE 1588 Precision Time Protocol (PTP) operation?
Yes. The integrated Ethernet MAC supports IEEE 1588-2008 PTP v2 via hardware timestamping on all receive and transmit frames. It provides sub-100 ns timestamp resolution and supports one-step and two-step clock synchronization modes for time-sensitive networking in automotive domain controllers.
