The R7F701431EABG#BC1 operates at a maximum CPU frequency of 200 MHz using its RH850 G3K core. This frequency is sustained under full temperature and voltage range conditions (−40°C to +125°C, VDD = 1.14–1.26 V), as validated in Renesas' characterization reports. The R7F701431EABG#BC1 achieves this performance with integrated PLL and low-jitter clock synthesis, enabling deterministic real-time response in automotive control loops.
Does the R7F701431EABG#BC1 support AUTOSAR-compliant software stacks?
Yes, the R7F701431EABG#BC1 is fully supported by Renesas' AUTOSAR 4.3-compliant MCAL (Microcontroller Abstraction Layer) drivers and has been validated with leading RTOS and BSW providers including ETAS ISOLAR and Vector DaVinci. Its hardware features - including MPU, ECC-protected memory, and lockstep-capable core - satisfy AUTOSAR OS memory protection and safety requirements. The R7F701431EABG#BC1 is listed in the official Renesas AUTOSAR partner ecosystem documentation.
What safety certifications apply to the R7F701431EABG#BC1?
The R7F701431EABG#BC1 is certified to ISO 26262:2018 ASIL-B at the component level, with FMEDA reports, safety manuals, and diagnostic coverage data provided by Renesas. It includes hardware safety mechanisms such as lockstep CPU mode, ECC on flash and RAM, memory protection unit (MPU), and built-in self-test (BIST) for CPU and memory subsystems. The R7F701431EABG#BC1 is not rated for ASIL-D out-of-box but can be used in ASIL-D systems when combined with appropriate system-level redundancy and monitoring.
Can the R7F701431EABG#BC1 execute code from RAM?
Yes, the R7F701431EABG#BC1 supports XIP (eXecute-In-Place) from flash and also allows execution from RAM via its flexible memory mapping unit (MMU). Critical real-time routines - such as interrupt service handlers or safety monitors - can be copied to RAM during initialization for deterministic latency and immunity to flash read interference. This capability is enabled and configured through the R7F701431EABG#BC1's memory protection unit and startup code sequence defined in Renesas' application note R01AN3817.
What debug interfaces does the R7F701431EABG#BC1 provide?
The R7F701431EABG#BC1 provides IEEE 1149.1-compliant JTAG (TRST/TCK/TMS/TDI/TDO) for boundary scan, flash programming, and full-core debugging, plus SWO (Serial Wire Output) for real-time trace streaming. It also supports ETM (Embedded Trace Macrocell) for instruction and data trace, accessible via Renesas' E2 emulator or third-party tools like Lauterbach TRACE32. All debug interfaces are active in both normal and low-power modes, and the R7F701431EABG#BC1 includes secure debug disable fuses for production security.
