FAQ

What safety certifications does the R7F7016514ABG-C#AC1 hold?

The R7F7016514ABG-C#AC1 is certified to ISO 26262 ASIL-D at the MCU level, with full FMEDA documentation, safety manual, and diagnostic coverage reports provided by Renesas. It meets AEC-Q100 Grade 1 reliability requirements for operation from −40°C to +125°C and includes hardware safety mechanisms such as lockstep CPU monitoring, ECC-protected memories, and BIST for flash/SRAM. The R7F7016514ABG-C#AC1 also supports end-to-end safety analysis per ISO 26262 Part 5 Annex D.

Does the R7F7016514ABG-C#AC1 support Ethernet AVB and CAN FD simultaneously?

Yes, the R7F7016514ABG-C#AC1 supports concurrent operation of its 100BASE-T1 Ethernet AVB controller and all five CAN FD interfaces. It features shared DMA resources and hardware timestamping synchronized across both Ethernet and CAN FD channels using the same 100 MHz reference clock, enabling time-coherent sensor fusion and deterministic message forwarding in domain controller applications. The R7F7016514ABG-C#AC1 implements IEEE 802.1AS-2011 timestamping and supports TSN traffic shaping for critical control frames.

What cryptographic functions are accelerated by the ICUMD in the R7F7016514ABG-C#AC1?

The ICUMD (Intelligent Cryptographic Unit – Master D) in the R7F7016514ABG-C#AC1 accelerates AES-128/256 (ECB/CBC/GCM modes), SHA-224/256, RSA-2048 signature generation/verification, and true random number generation (TRNG). It operates independently of the CPU cores, reducing software overhead for secure boot, encrypted OTA updates, and TLS handshake offload. The R7F7016514ABG-C#AC1 uses ICUMD to achieve sub-10 µs latency for AES-256-GCM operations critical to real-time firmware authentication.

What is the maximum operating frequency and power supply configuration for the R7F7016514ABG-C#AC1?

The R7F7016514ABG-C#AC1 operates at a maximum CPU frequency of 240 MHz with dual-core lockstep execution. It requires three primary supply rails: VDDC (1.2 V ±5% core), VDDA (3.3 V ±5% analog), and eight independent VDDIO domains (3.3 V ±5% each) for I/O voltage flexibility. All supplies feature built-in brown-out detection and reset assertion, and the R7F7016514ABG-C#AC1 supports dynamic voltage and frequency scaling (DVFS) across seven low-power modes with wake-up latency as low as 5 µs from standby.

Is the R7F7016514ABG-C#AC1 pin-compatible with other RH850/F1KM variants?

The R7F7016514ABG-C#AC1 uses the 256-pin LQFP package shared across the RH850/F1KM-S4 family, including R7F7016524ABG-C#AC1 and R7F7016414ABG-C#AC1. Pin assignments for power, reset, clock, JTAG, CAN FD, Ethernet, and general-purpose I/O are identical within the S4 subgroup. However, peripheral enablement (e.g., number of active CAN FD channels or Ethernet features) is configured via fuse settings and software initialization - the R7F7016514ABG-C#AC1 itself is not pin-compatible with S2 or S1 variants due to differing pin multiplexing and safety monitor signal routing.
