FAQ

What safety certifications does the R7F7016473AFP-C#BA1 hold?

The R7F7016473AFP-C#BA1 is certified to ISO 26262 ASIL-D at the MCU level, with hardware safety mechanisms including dual-core lockstep comparison, ECC on flash and parity on SRAM, built-in self-test (BIST) for memories and logic, and safety monitor IP for peripherals. Renesas provides FMEDA reports, safety manuals, and diagnostic software libraries to support customer safety case development for the R7F7016473AFP-C#BA1.

Does the R7F7016473AFP-C#BA1 support CAN FD with hardware wake-up?

Yes, the R7F7016473AFP-C#BA1 integrates five fully compliant CAN FD controllers (per ISO 11898-1:2015) with dedicated hardware wake-up logic. Each CAN FD channel can detect specific data patterns or identifier matches while the CPU is in deep stop mode, asserting an interrupt without requiring core wake-up - enabling ultra-low-power listening for critical bus events in the R7F7016473AFP-C#BA1.

What is the maximum operating temperature rating for the R7F7016473AFP-C#BA1?

The R7F7016473AFP-C#BA1 is qualified for operation from –40°C to +150°C ambient temperature and meets AEC-Q100 Grade 0 requirements. This extended range is validated across all functional blocks - including CPU, flash, ADC, and CAN FD transceivers - making it suitable for under-hood automotive applications such as engine control where sustained high-temperature exposure occurs.

How much on-chip flash and RAM does the R7F7016473AFP-C#BA1 include?

The R7F7016473AFP-C#BA1 includes 4 MB of embedded flash memory with ECC protection and 512 KB of SRAM with parity checking. Additionally, it features 64 KB of Tightly Coupled Memory (TCM) for time-critical code and data, ensuring deterministic access latency independent of bus arbitration - a key design feature of the R7F7016473AFP-C#BA1 for real-time automotive control.

Is the R7F7016473AFP-C#BA1 pin-compatible with other RH850/F1KH variants?

The R7F7016473AFP-C#BA1 uses the RH850/F1KH-D8 variant pinout in a 176-pin LQFP package. It shares identical pin mapping with other F1KH-D8 members such as R7F7016483AFP-C#BA1, enabling drop-in replacement where flash/SRAM capacity differences are acceptable. However, it is not pin-compatible with F1KM-S4 or F1KM-S2 variants due to differing peripheral allocations and power domain assignments.
