FAQ
What safety certifications does TC397XP256F300SBCLXUMA1 support?
TC397XP256F300SBCLXUMA1 is certified to ISO 26262 ASIL-D at the hardware level, with supporting documentation including FMEDA reports, safety manuals, and diagnostic coverage analysis. It meets IEC 61508 SIL3 requirements and includes hardware safety mechanisms such as lockstep core comparison, memory ECC, and SMU-monitored clock supervision.
Does TC397XP256F300SBCLXUMA1 include an integrated Ethernet PHY?
No, TC397XP256F300SBCLXUMA1 integrates only the Ethernet MAC layer with TSN capabilities (IEEE 802.1AS/802.1Qbv). An external PHY chip is required for physical layer connectivity, and the device provides RMII/MII interfaces with configurable slew rate and termination controls for direct PHY interfacing.
How is flash memory protected against corruption in TC397XP256F300SBCLXUMA1?
Flash protection includes ECC with single-bit correction and multi-bit detection, sector-level write protection, read-while-write capability with bank interleaving, and hardware-assisted secure boot verification using SHA-256 and RSA-2048 signatures. All flash accesses are monitored by the Safety Management Unit for timing violations and access anomalies.
Can TC397XP256F300SBCLXUMA1 operate without external watchdog circuitry?
Yes - it includes an integrated Windowed Watchdog Timer (WWDT) with independent clock source, programmable timeout windows, and failure escalation to system reset or safe state activation. The WWDT is monitored by the Safety Island and supports both functional and safety-critical timeout configurations without external components.
