FAQ

What is the maximum operating frequency of the R7F7016233AFP-C#AA3?

The R7F7016233AFP-C#AA3 operates at a maximum CPU frequency of 200 MHz per core in lockstep mode. This frequency is sustained across the full –40°C to +125°C ambient temperature range with appropriate voltage regulation and thermal management. The R7F7016233AFP-C#AA3 achieves deterministic real-time performance through synchronized dual-core execution at this rate, verified by internal clock domain monitoring circuits.

Does the R7F7016233AFP-C#AA3 support ISO 26262 ASIL-D certification out of the box?

The R7F7016233AFP-C#AA3 is designed to meet ISO 26262 ASIL-D requirements and includes hardware safety mechanisms such as dual-core lockstep comparison, SEC-DED flash ECC, parity-protected RAM, and a configurable Safety Management Unit (SMU). However, full ASIL-D certification requires system-level validation including software safety analysis, FMEDA, and hardware fault tolerance testing - the R7F7016233AFP-C#AA3 provides the foundational hardware capabilities needed to achieve it.

What Ethernet standards does the R7F7016233AFP-C#AA3 support?

The R7F7016233AFP-C#AA3 integrates a hardware Ethernet AVB controller compliant with IEEE 802.3av, supporting time-sensitive streaming over standard 100BASE-TX physical layers. It provides hardware timestamping with 100 ns resolution, traffic shaping registers, and AVB-specific frame prioritization. The R7F7016233AFP-C#AA3 does not support IEEE 802.3bz (2.5G/5G) or TSN extensions beyond AVB baseline features.

How many CAN FD channels does the R7F7016233AFP-C#AA3 include?

The R7F7016233AFP-C#AA3 integrates three independent CAN FD controllers compliant with ISO 11898-1:2015, each supporting data bit rates up to 5 Mbps and nominal bit rates up to 1 Mbps. All three controllers feature message RAM with configurable FIFOs, loopback self-test modes, and direct integration with the Safety Management Unit for fault reporting - a key capability of the R7F7016233AFP-C#AA3 in multi-bus automotive networks.

Is the R7F7016233AFP-C#AA3 pin-compatible with other RH850/F1K variants?

The R7F7016233AFP-C#AA3 uses a 256-pin LQFP package shared with several RH850/F1K family members, but pin compatibility is not guaranteed across all variants. Specific signal assignments - especially for Ethernet AVB, CAN FD, and safety monitor pins - differ between part numbers. Always verify pin mapping against the R7F7016233AFP-C#AA3-specific hardware manual before board reuse; the R7F7016233AFP-C#AA3 has unique pin allocations for its triple CAN FD and single AVB interface.
