FAQ
What is the maximum operating frequency of the R7F7015973AFP-C#AA3?
The R7F7015973AFP-C#AA3 operates at a maximum CPU frequency of 200 MHz under specified voltage and temperature conditions. This performance is sustained across its full AEC-Q100 Grade 1 range (−40°C to +125°C) with appropriate thermal design and power supply regulation. The R7F7015973AFP-C#AA3 achieves this using a dual-voltage domain architecture with 1.2V core and 3.3V I/O supplies.
Does the R7F7015973AFP-C#AA3 support ISO 26262 ASIL-D certification out of the box?
The R7F7015973AFP-C#AA3 is ASIL-D ready with integrated hardware safety mechanisms including dual-core lockstep execution, ECC on flash and SRAM, memory BIST, and a dedicated safety management unit (SMU). However, full ISO 26262 ASIL-D certification requires system-level validation, safety case documentation, and tool qualification - capabilities enabled but not automatically conferred by the R7F7015973AFP-C#AA3 alone.
How many CAN FD interfaces does the R7F7015973AFP-C#AA3 provide?
The R7F7015973AFP-C#AA3 integrates five independent CAN FD controllers compliant with ISO 11898-1:2015, each supporting data rates up to 5 Mbps and frame payloads up to 64 bytes. All five controllers share common register structures and support loopback, self-test, and hardware timestamping modes. This enables scalable networking in multi-domain automotive architectures without external CAN FD bridge ICs.
What package type and pin count does the R7F7015973AFP-C#AA3 use?
The R7F7015973AFP-C#AA3 uses a 176-pin LQFP package measuring 24mm × 24mm with 0.5mm pitch. This package is optimized for automotive PCB assembly, supports standard reflow profiles, and provides dedicated power/ground pin distribution for EMI suppression and signal integrity. The R7F7015973AFP-C#AA3 pinout is fully compatible with other RH850/F1K devices in the same package variant.
Is background flash programming supported on the R7F7015973AFP-C#AA3?
Yes, the R7F7015973AFP-C#AA3 supports background flash programming (BFP), allowing code execution from flash while simultaneously erasing and programming non-active sectors. This capability enables over-the-air (OTA) firmware updates and runtime parameter storage without halting application execution. The R7F7015973AFP-C#AA3 implements sector-level protection and erase suspend/resume functions to maintain deterministic real-time behavior.
