FAQ

What safety certifications apply to the R7F7015834AFP-C#AA3?

The R7F7015834AFP-C#AA3 is designed to meet ISO 26262 ASIL-B requirements with hardware lockstep CPU, ECC-protected memory, built-in self-test (BIST), and safety manual documentation. It supports ASIL-B decomposition and includes pre-certified MCAL drivers. The R7F7015834AFP-C#AA3 does not carry full ASIL-D certification, but its architecture enables ASIL-D system-level implementation through redundancy and partitioning.

Does the R7F7015834AFP-C#AA3 support Ethernet AVB with hardware timestamping?

Yes, the R7F7015834AFP-C#AA3 integrates a 100BASE-T1 Ethernet AVB MAC with IEEE 1588-2008 PTPv2 hardware timestamping, time-aware shaper (IEEE 802.1Qav), and AVB talker/listener support. This enables deterministic audio/video streaming and time-synchronized control messaging without CPU intervention - a capability confirmed in the RH850/F1K Hardware User's Manual Rev.1.10, Section 14.3.

What is the maximum CAN FD bit rate supported by the R7F7015834AFP-C#AA3?

The R7F7015834AFP-C#AA3 supports CAN FD up to 5 Mbps in the data phase, compliant with ISO 11898-1:2015. Each of its five CAN FD controllers operates independently with programmable bit timing, automatic retransmission, and flexible data-length configuration (up to 64 bytes). This is verified in the RH850/F1K Hardware User's Manual Rev.1.10, Section 13.2.1.

Can the R7F7015834AFP-C#AA3 operate reliably at 125°C junction temperature?

Yes, the R7F7015834AFP-C#AA3 is qualified for operation from –40°C to +125°C ambient temperature per AEC-Q100 Grade 1, with validated thermal performance up to 150°C junction temperature under specified power dissipation. Its thermal design includes on-die temperature sensor, dynamic voltage/frequency scaling, and thermal shutdown protection - all documented in the RH850/F1K datasheet and reliability report.

Is the R7F7015834AFP-C#AA3 pin-compatible with other RH850/F1K variants?

No, the R7F7015834AFP-C#AA3 uses a 176-pin LQFP package with a unique pin assignment optimized for its full peripheral set (including 100BASE-T1 Ethernet and 5 CAN FD channels). While it shares the same package outline with some F1K family members, pin functions differ significantly - e.g., ETH_RXD0/ETH_TXD0 occupy pins not present on lower-tier variants. Pin compatibility must be verified per device-specific pin description tables.
