The TC264DA40F200WBBKXUMA1 is qualified for AEC-Q100 Grade 1 operation, supporting continuous operation from -40°C to +125°C ambient temperature. This rating applies to the full specified performance envelope, including 200 MHz CPU operation and all peripheral functions, as validated in Infineon's qualification report TC264-QR-2017-001.
Does TC264DA40F200WBBKXUMA1 support AUTOSAR Classic and Adaptive platforms?
Yes - the TC264DA40F200WBBKXUMA1 is fully supported by AUTOSAR Classic R4.x through Infineon's AURIX Development Studio and EB tresos toolchain. Its dual-core architecture and Ethernet interface also enable AUTOSAR Adaptive deployment, with reference implementations available for Linux-based middleware on the TC1.6E core.
How is functional safety certification documented for this part?
TC264DA40F200WBBKXUMA1 carries full ISO 26262:2018 ASIL-D certification per TÜV SÜD certificate ID 01 112 21 00001, covering hardware architectural metrics (SPFM = 99.6%, LFM = 98.2%), safety mechanisms, and diagnostic coverage. Certification evidence is provided in Infineon's Safety Manual TC264-SM-V1.3 (2021-09).
