FAQ
What is the maximum junction temperature rating for SAL-TC298TP-128F300N BC?
The device is qualified for operation up to 150°C junction temperature, validated per AEC-Q100 Grade 0 requirements. Thermal design must maintain Tj ≤ 150°C under worst-case power dissipation (2.8 W typical at 300 MHz, full peripheral activation), using the exposed thermal pad and recommended PCB copper pour layout per Infineon's BGA416 thermal guidelines.
Does SAL-TC298TP-128F300N BC support over-the-air (OTA) firmware updates?
Yes-it supports secure OTA updates via its Ethernet MAC and integrated HSM, using DFLASH for atomic bank-swapped firmware storage. The bootloader validates signed images using SHA-256 and RSA-2048 before execution, and flash ECC ensures update integrity during programming and runtime.
How is functional safety certification documented for this microcontroller?
Infineon provides ISO 26262 ASIL-D ready documentation including FMEDA reports, safety manual, hardware/software safety analysis, and diagnostic coverage data. The SAL-TC298TP-128F300N BC is pre-certified for use in ASIL-D systems when integrated per the safety manual and with certified toolchains (e.g., TASKING TriCore v6.3+).
Can the ERAY interface operate concurrently with Ethernet and CAN FD?
Yes-the SRI crossbar enables full concurrency: ERAY, Ethernet MAC, and all six CAN FD controllers operate simultaneously without arbitration delay. Each has dedicated DMA channels and priority-configurable interrupt vectors, allowing deterministic scheduling of time-critical frames (e.g., ERAY safety messages at 100 µs intervals alongside 100 Mbps Ethernet traffic).
