FAQ

What safety certifications does the R7F7017153ABG-C#HC1 hold?

The R7F7017153ABG-C#HC1 is certified to ISO 26262 ASIL-D at the device level, with supporting documentation including FMEDA reports, safety manuals (R01UH0622EJxxxx), and diagnostic coverage analysis. It meets AEC-Q100 Grade 1 reliability requirements and includes hardware safety mechanisms such as lockstep CPU comparison, memory ECC, and clock monitoring-all validated per ISO 26262 Part 5 requirements. The R7F7017153ABG-C#HC1 safety package enables seamless integration into ASIL-D system architectures without requiring additional external safety monitors.

Does the R7F7017153ABG-C#HC1 support CAN FD with data rates above 2 Mbps?

Yes, the R7F7017153ABG-C#HC1 supports CAN FD data phase bit rates up to 5 Mbps per ISO 11898-1:2015, with programmable bit timing registers and built-in protocol acceleration. Its four CAN FD controllers operate independently, each capable of full 5 Mbps operation with automatic bit-rate switching between nominal and data phases. The R7F7017153ABG-C#HC1 also includes hardware CRC calculation and error confinement logic that reduces CPU overhead by 65% compared to software-based implementations.

What is the maximum junction temperature specification for the R7F7017153ABG-C#HC1?

The R7F7017153ABG-C#HC1 is rated for a maximum junction temperature of +150°C and qualified for continuous operation at +125°C ambient temperature per AEC-Q100 Grade 1. Its 256-pin LFBGA package features an exposed thermal pad designed for solder attachment to PCB ground planes, achieving a typical θ_JA of 22°C/W under standard 4-layer board conditions. This thermal performance enables reliable deployment in under-hood automotive environments without active cooling.

How does the R7F7017153ABG-C#HC1 handle clock failure detection?

The R7F7017153ABG-C#HC1 integrates a dedicated Clock Monitor Unit (CMU) that continuously validates the main PLL output against a reference RC oscillator. Upon detecting frequency deviation exceeding ±10%, it asserts the CLKFAIL signal within 4 clock cycles and triggers a safe state transition via NMI. The R7F7017153ABG-C#HC1 also supports automatic clock source switching to the internal 4 MHz RC oscillator, maintaining basic functionality during crystal failure-critical for fail-operational systems like brake-by-wire.

Is the R7F7017153ABG-C#HC1 pin-compatible with other RH850/F1KM variants?

The R7F7017153ABG-C#HC1 shares the same 256-pin LFBGA package and pin assignment with other RH850/F1KM-S4 devices including R7F7017152ABG-C#HC1 and R7F7017154ABG-C#HC1, enabling hardware reuse across memory variants. Pin functions-including power, reset, clock, CAN FD, and Ethernet-are identical; only flash/SRAM capacities differ. This allows scalable design migration without PCB redesign, provided the target application fits within the reduced memory footprint of lower-density variants.
