It meets AEC-Q100 Grade 1 reliability requirements and includes hardware safety mechanisms such as lockstep CPU comparison, SMU-controlled self-tests, and full ECC on flash and parity on SRAM. The R7F7016913AFP-C#BA1 safety package is validated for use in automotive safety-related systems up to ASIL-D decomposition levels.

Does the R7F7016913AFP-C#BA1 support Ethernet AVB with time-sensitive networking (TSN)?

Yes, the R7F7016913AFP-C#BA1 integrates a 100BASE-T1 Ethernet AVB controller compliant with IEEE 802.1Qbv time-aware shaper, enabling deterministic scheduling of safety-critical traffic with guaranteed latency ≤100 μs. It supports frame preemption, gate control lists, and credit-based shaping for seamless integration into automotive zonal architectures. The R7F7016913AFP-C#BA1 Ethernet interface operates without external PHY, reducing BOM cost and board space versus solutions requiring discrete MAC+PHY combinations.

How many CAN FD interfaces does the R7F7016913AFP-C#BA1 provide, and what is their maximum data rate?

The R7F7016913AFP-C#BA1 integrates five independent CAN FD controllers, each supporting nominal bit rates up to 1 Mbps and data phase bit rates up to 5 Mbps. All channels support ISO 11898-1:2015 compliance, flexible data-length configuration (up to 64 bytes), and built-in CRC calculation with error confinement. The R7F7016913AFP-C#BA1 CAN FD modules are fully configurable via register sets and support loopback testing, automatic retransmission, and error counters accessible through the SMU interface.

What cryptographic functions are accelerated by the ICUMD in the R7F7016913AFP-C#BA1?

The Intelligent Cryptographic Unit (ICUMD) in the R7F7016913AFP-C#BA1 accelerates AES-128 and AES-256 encryption/decryption in ECB/CBC/CTR/GCM modes, SHA-256 hashing, and RSA-2048 signature generation and verification. It includes a secure key vault with tamper-resistant storage and supports secure boot authentication using public-key infrastructure. The R7F7016913AFP-C#BA1 ICUMD offloads crypto operations from the main CPU, reducing firmware signing latency by 70% compared to software-only implementations.

Is the R7F7016913AFP-C#BA1 pin-compatible with other RH850/F1KH variants?

The R7F7016913AFP-C#BA1 uses the 256-pin LFBGA package shared across the RH850/F1KH-D8 family, including R7F7016923AFP-C#BA1 and R7F7016893AFP-C#BA1. Pin functions are consistent for power, reset, clock, JTAG, and primary peripheral signals; however, some alternate function pins differ based on peripheral enablement (e.g., Ethernet vs. additional CAN FD). The R7F7016913AFP-C#BA1 is not drop-in compatible with F1KM-series parts due to distinct pin mapping and safety architecture differences.
