FAQ
What safety certifications does the SAK-TC297T-96F300N BC hold?
The SAK-TC297T-96F300N BC is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C) and supports ISO 26262 ASIL-D compliance through integrated hardware safety mechanisms-including lockstep CPU cores, ECC on all memories, safe DMA, and BIST. Infineon provides certified safety manuals, FMEDA reports, and diagnostic software libraries to accelerate ASIL-D system certification.
Does this MCU include an integrated Ethernet PHY?
No, the SAK-TC297T-96F300N BC integrates only a 100 Mbps Ethernet MAC with MII and RMII interfaces. An external PHY (e.g., Infineon TLF35584 or compatible IEEE 802.3-compliant device) is required for physical layer connectivity. The MAC supports time-stamping, checksum offload, and AVB/TSN-ready register sets for deterministic networking.
How is flash memory partitioned and protected on this device?
It features 4 MB of ECC-protected program flash (PFLASH) and 512 KB of data flash (DFLASH) usable for EEPROM emulation. Both are segmented into sectors with independent write/erase control and hardware-based protection (SPB, WPROT). PFLASH supports secure boot via BootROM (BROM) with hash verification and encrypted firmware loading using HSM.
What debug and programming interfaces are supported?
The device supports JTAG and DAP (Debug Access Port) interfaces for boundary-scan, SWD, and serial wire debug. It includes a dedicated debug trace port (ETM) capable of streaming instruction and data trace at full CPU speed, plus secure debug authentication via HSM keys to prevent unauthorized access during development or field updates.
