FAQ

What safety certifications does the R7F7015813AFP-C#BA3 hold?

The R7F7015813AFP-C#BA3 is certified to ISO 26262 ASIL-D at the hardware level, with FMEDA reports, safety manuals, and diagnostic coverage data provided by Renesas. It meets AEC-Q100 Grade 1 requirements (–40°C to +125°C) and includes built-in self-test (BIST) for CPU, memory, and peripheral safety mechanisms. The R7F7015813AFP-C#BA3 supports systematic safety development according to ISO 26262 Part 4 and Part 5, with documented failure modes and mitigation strategies.

Does the R7F7015813AFP-C#BA3 support CAN FD with simultaneous operation on all five channels?

Yes, the R7F7015813AFP-C#BA3 supports concurrent operation of all five CAN FD controllers, each independently configurable for nominal/data bit rates up to 1 Mbps / 5 Mbps. Each channel has dedicated message RAM with ECC protection and hardware timestamping, enabling deterministic scheduling in time-triggered networks. The R7F7015813AFP-C#BA3 includes arbitration logic to prevent bus conflicts during simultaneous transmission attempts.

What cryptographic algorithms are accelerated by the ICUMD in the R7F7015813AFP-C#BA3?

The ICUMD (Intelligent Cryptographic Unit / Master D) in the R7F7015813AFP-C#BA3 accelerates AES-128/256 (ECB/CBC/GCM modes), SHA-256, RSA-2048 signature generation/verification, and ECC NIST P-256 operations. It supports secure key storage in tamper-resistant memory and enables hardware-verified secure boot in under 50 ms. The R7F7015813AFP-C#BA3 uses ICUMD to enforce chain-of-trust from ROM bootloader through application firmware.

How is functional safety implemented in the dual-core architecture of the R7F7015813AFP-C#BA3?

The R7F7015813AFP-C#BA3 implements functional safety through strict lockstep execution: both RH850G3K-H cores execute identical instructions simultaneously, with cycle-accurate comparison logic detecting mismatches within one clock cycle. Detected faults trigger immediate shutdown of non-safe peripherals and transition to defined safe states via the Safety Management Unit (SMU). The R7F7015813AFP-C#BA3 includes redundant clock and voltage monitors feeding into the SMU for cross-domain fault detection.

What is the maximum operating frequency and thermal specification for the R7F7015813AFP-C#BA3?

The R7F7015813AFP-C#BA3 operates at a maximum CPU frequency of 400 MHz with all peripherals active, sustained under AEC-Q100 Grade 1 conditions (–40°C to +125°C ambient). Its thermal design allows continuous operation at junction temperatures up to +150°C, verified through package-level thermal resistance measurements (θJA = 22°C/W typical). The R7F7015813AFP-C#BA3 includes on-die temperature sensors with programmable thresholds for thermal throttling and safe shutdown.
