FAQ
What is the safety certification status of the R7F7016473AFP-C#KA1?
The R7F7016473AFP-C#KA1 is designed to support ISO 26262 ASIL-B compliance at the system level. It includes dual-core lockstep CPU, hardware safety monitor (HSM), memory BIST, and diagnostic libraries. Renesas provides FMEDA reports and safety manuals to aid customer certification - the R7F7016473AFP-C#KA1 itself is not pre-certified, but its architecture and documentation enable ASIL-B implementation per ISO 26262 Part 5 and Part 6.
Does the R7F7016473AFP-C#KA1 support CAN FD with bit-rate switching?
Yes, the R7F7016473AFP-C#KA1 integrates five fully compliant CAN FD controllers supporting ISO 11898-1:2015, including seamless bit-rate switching between arbitration (up to 1 Mbps) and data phase (up to 5 Mbps). Each controller includes dedicated message RAM, hardware filtering, and loopback self-test modes - all accessible via the R7F7016473AFP-C#KA1's CANFDn registers.
What is the maximum operating frequency of the R7F7016473AFP-C#KA1?
The R7F7016473AFP-C#KA1 operates at a maximum CPU frequency of 160 MHz under specified conditions (VDD_1P2 = 1.2 V, TA = –40°C to +125°C). This frequency is achieved using the on-chip PLL with external crystal input (4–20 MHz), and the core maintains timing closure across the full automotive temperature range - verified in the R7F7016473AFP-C#KA1 characterization report.
How does the R7F7016473AFP-C#KA1 handle secure firmware updates?
The R7F7016473AFP-C#KA1 supports secure over-the-air (OTA) updates via its integrated Hardware Security Module (HSM), which performs ECDSA signature verification of firmware images prior to flash programming. The R7F7016473AFP-C#KA1's ROM bootloader enforces chain-of-trust execution, and encrypted firmware can be decrypted in real time using AES-128 keys stored in protected memory - all implemented in hardware to prevent side-channel leakage.
Is the R7F7016473AFP-C#KA1 pin-compatible with other RH850/F1KH variants?
The R7F7016473AFP-C#KA1 uses a 176-pin LQFP package shared with several RH850/F1KH-D8 variants, but pin compatibility is not guaranteed across all functions. While power, ground, reset, and clock pins align, peripheral pin assignments (e.g., CAN FD, ADC, GPTA) differ between part numbers due to feature masking and routing constraints. Always verify pin mapping against the R7F7016473AFP-C#KA1-specific datasheet before board reuse.
