FAQ
What is the maximum operating frequency of each CPU core in the TC264D40F200WBBKXUMA1?
The TC264D40F200WBBKXUMA1 features two TriCore CPUs both rated for up to 200 MHz operation across the full industrial temperature range (–40 °C to +125 °C). This is confirmed in the "Summary of Features" section (page 1-1) and "Electrical Specification" chapter (Section 3.4) of the official Infineon datasheet V1.0 (2017-06), with timing validated under worst-case voltage and temperature conditions.
Does the TC264D40F200WBBKXUMA1 include hardware support for AUTOSAR OS and MCAL?
Yes - the TC264D40F200WBBKXUMA1 is fully supported by Infineon's AURIX Development Studio and AUTOSAR-compliant MCAL 4.3+ drivers. Its SMU, lockstep core, ECC memory, and standardized peripheral registers enable certified AUTOSAR OS scheduling, memory protection, and safety monitoring per ASIL-D requirements.
What safety certifications does the TC264D40F200WBBKXUMA1 hold?
The TC264D40F200WBBKXUMA1 is qualified to AEC-Q100 Grade 1 and supports ISO 26262 ASIL-D development per Infineon's certified safety concept documentation (Safety Manual TC26x v1.3). It includes hardware safety mechanisms such as lockstep execution, ECC on all memories, SMU with fault injection, and dedicated ESTOP pins - all verified in the certified safety case.
Is the TC264D40F200WBBKXUMA1 pin-compatible with other TC26x family members?
No - the TC264D40F200WBBKXUMA1 uses LQFP-144 packaging, while TC265 variants use LQFP-176 and TC267 variants use BGA-292. Pin mapping differs across packages due to distinct peripheral sets and routing constraints; no mechanical or electrical pin compatibility exists between TC264, TC265, and TC267 derivatives.
