FAQ
What safety certifications does TC264DA40F200NBCKXUMA2 support?
TC264DA40F200NBCKXUMA2 is qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C) and supports ISO 26262 ASIL-D development workflows. Its hardware safety features - including lockstep CPU cores, ECC on all memories, SMU with configurable monitors, and safety DMA - are documented in Infineon's Safety Manual (V1.2, 2017) and certified by TÜV SÜD for use in safety-critical automotive systems.
Does this MCU support Ethernet Time-Sensitive Networking (TSN)?
No - TC264DA40F200NBCKXUMA2 includes a standard 10/100 Ethernet MAC compliant with IEEE 802.3, but lacks hardware TSN features such as time-aware shapers, frame preemption, or precise timestamping required for TSN. It supports time-triggered communication via E-Ray and ASC with deterministic scheduling, which is commonly used in automotive instead of TSN.
Can TC264DA40F200NBCKXUMA2 operate with only a 3.3 V supply?
Yes - it operates from a single 3.3 V ±5 % supply (VDDP_3V3) for I/O and core logic. The analog supply (VDDA_3V3) must also be 3.3 V. While some I/O pins are 5 V tolerant, no 5 V supply rail is required. The device does not support internal 5 V generation or mixed-voltage operation beyond specified I/O tolerance.
Is there a recommended programming/debug interface for production flashing?
Production flashing is supported via JTAG or DAP (Debug Access Port) using Infineon's MemTool or iLLD-based bootloader. For high-volume manufacturing, the device supports serial wire debug (SWD) mode over DAP with secure boot authentication. Flash programming requires Infineon's TriCore™ toolchain (TASKING or GCC-based) and compatible debug probes (e.g., Lauterbach TRACE32 or Segger J-Link).
