FAQ

What safety certifications does the R7F7016873AFP-C#BA1 hold?

The R7F7016873AFP-C#BA1 is certified to ISO 26262 ASIL-B at the device level, with hardware safety mechanisms including dual-core lockstep comparison, flash ECC, RAM parity/ECC, clock failure detection, and MPU-based memory protection. Renesas provides FMEDA reports and safety manuals supporting system-level ASIL-B integration. The R7F7016873AFP-C#BA1 meets AEC-Q100 Grade 0 qualification for operation from –40°C to +150°C.

Does the R7F7016873AFP-C#BA1 support CAN FD with data rates above 2 Mbps?

Yes, the R7F7016873AFP-C#BA1 integrates five fully independent CAN FD controllers compliant with ISO 11898-1:2015, each capable of data phase bit rates up to 5 Mbps. Its internal clock system supports precise bit timing configuration, and the CAN FD modules include hardware timestamping and flexible data length (up to 64 bytes) with CRC-17/21 protection. This capability is confirmed in the RH850/F1KH Hardware User's Manual Rev.1.30, Section 1A.2.

What is the maximum operating frequency of the R7F7016873AFP-C#BA1?

The R7F7016873AFP-C#BA1 operates at a maximum system clock frequency of 200 MHz, achieved via its on-chip PLL using an external 8–20 MHz crystal input. The dual RH850 G3KH cores execute at full 200 MHz with zero wait-state access to on-chip flash and SRAM. This frequency is sustained across the full –40°C to +150°C temperature range under specified VDD_MAIN and VDD_IO supply conditions.

How does the R7F7016873AFP-C#BA1 handle cryptographic operations?

The R7F7016873AFP-C#BA1 includes the Intelligent Cryptographic Unit (ICUMD), a dedicated hardware accelerator supporting AES-128/256 encryption/decryption, SHA-256 hashing, and RSA-2048 signing/verification. ICUMD features a secure key vault with tamper detection and operates independently of the CPU, reducing latency - e.g., AES-128 encryption completes in under 100 clock cycles. This is documented in the RH850/F1KH ICUMD User's Manual R01UH0705EJxxxx.

Is the R7F7016873AFP-C#BA1 pin-compatible with other RH850/F1KH variants?

The R7F7016873AFP-C#BA1 uses the 176-pin LQFP package shared across the RH850/F1KH-D8 series, including R7F7016883AFP-C#BA1 and R7F7016893AFP-C#BA1. Pin functions, power domains, and peripheral mappings are identical; only flash/SRAM capacities differ. No PCB changes are required when migrating between these variants, as confirmed in Section 2A.1 (Pin Connection Diagram) of the RH850/F1KH Hardware User's Manual Rev.1.30.
