Frequently Asked Questions
Q1: Is your currently available stock of the SAK-TC397XP-256F300S BC microcontroller 100% genuine and original?
A: Yes, we guarantee that all SAK-TC397XP-256F300S BC devices in our inventory are 100% brand-new, factory-original products directly from Infineon Technologies. Every batch is tracked, logged, and shipped inside standard moisture-barrier bags with strict anti-static ESD shielding measures.
Q2: What do the code markers “SAK” and “BC” specifically represent in this microcontroller’s naming convention?
A: In Infineon’s automotive IC product coding, the “SAK” prefix designates an operating ambient temperature range of -40°C to +125°C (Automotive Grade 1). The “BC” suffix identifies the precise design revision stepping and packaging layout variant of the AURIX™ TC3xx silicon core.
Q3: How does the internal lockstep architecture of this chip achieve ASIL-D functional safety ratings?
A: The chip pairs four of its primary processing cores with matching physical lockstep slave cores. These slave cores run the exact same instructions in parallel with a minor clock delay cycle. Dedicated hardware checkers continuously compare outputs across the pairs, instantly triggering a safety interrupt fault if any processing mismatch is detected.
Q4: How can our engineering development team request full pinout charts, software toolchains, or high-volume wholesale pricing schedules?
A: Please complete our Quick Inquiry web form on this page with details about your project parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
