FAQ
What is the maximum operating junction temperature for TC397XP256F300SBCKXUMA1?
The TC397XP256F300SBCKXUMA1 has a rated maximum junction temperature of 150°C, validated per AEC-Q100 Grade 1 qualification. Thermal derating begins at 125°C ambient with forced airflow, and the device includes on-die temperature sensors with programmable thresholds for thermal shutdown.
Does TC397XP256F300SBCKXUMA1 support JTAG debugging in lockstep mode?
Yes - JTAG debugging remains fully operational during lockstep execution. The debug interface accesses both cores simultaneously, and breakpoints trigger on identical instruction addresses across both cores. Debug halt does not disable lockstep comparison, preserving safety state integrity during development.
How is flash ECC configured and verified during runtime?
Flash ECC is enabled by default at power-on and managed by the Flash Controller Unit (FCU). It performs single-bit correction and double-bit detection on every read access. Runtime verification is supported via FCU status registers and interrupt flags, and ECC error logs are stored in dedicated SMU-accessible memory locations for diagnostic reporting.
Can TC397XP256F300SBCKXUMA1 operate without external crystal oscillator?
No - the device requires an external 40 MHz crystal oscillator connected to XIN/XOUT pins for primary clock generation. Internal RC oscillators are only used for wake-up and fail-safe modes and lack the stability needed for TSN timestamping or ASIL-D timing compliance.
