FAQ
What is the maximum ambient temperature rating for SAK-TC297TC-96F300S BC?
The device is qualified for operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. Junction temperature must remain below 150°C under worst-case power dissipation, which is ensured by the BGA292 thermal pad and recommended PCB copper pour design per Infineon's thermal guidelines.
Does SAK-TC297TC-96F300S BC support CAN FD natively in hardware?
No hardware CAN FD controller is integrated; however, ASCLIN peripherals support CAN FD physical layer signaling via software-defined bit timing and protocol stack implementation. E-Ray and Ethernet interfaces provide higher-bandwidth deterministic alternatives for safety-critical networks.
How is functional safety certification documented for this microcontroller?
Infineon provides ISO 26262 ASIL-D ready documentation including FMEDA reports, safety manuals, and diagnostic coverage analysis. The device achieves ASIL-D via lockstep CPU, ECC memory, and safe peripheral design-not as a fully certified subsystem, but as a component meeting requirements for integration into certified systems.
What debug interface does SAK-TC297TC-96F300S BC use?
It uses Infineon's DAP (Debug Access Port) interface compliant with ARM CoreSight, accessible via JTAG or SWD. Debug capabilities include real-time trace, hardware breakpoints, and memory access during run-time, supported by tools like Lauterbach TRACE32 and iSYSTEM winIDEA.
