FAQ

What is the maximum operating frequency of the R7F7010303AFP-C#KA4?

The R7F7010303AFP-C#KA4 operates at a maximum CPU frequency of 200 MHz under AEC-Q100 Grade 1 conditions (−40°C to +125°C). This frequency is sustained across its full voltage range (1.14 V to 1.32 V for core supply) and validated with worst-case timing analysis per ISO 26262 tool qualification requirements. The R7F7010303AFP-C#KA4 achieves this performance while maintaining dual-core lockstep synchronization and ECC overhead.

Does the R7F7010303AFP-C#KA4 support JTAG debugging and boundary scan?

Yes, the R7F7010303AFP-C#KA4 supports IEEE 1149.1-compliant JTAG debugging via dedicated TCK/TMS/TDI/TDO pins and TRSTn. It enables full boundary-scan testing, real-time trace capture using the on-chip ETM (Embedded Trace Macrocell), and secure debug authentication through the ICUMD module. Debug access is configurable via fuse settings to enforce production lockdown after programming.

What safety documentation is provided for the R7F7010303AFP-C#KA4?

Renesas provides a complete ISO 26262 ASIL-D safety package for the R7F7010303AFP-C#KA4, including the Safety Manual (R01UH0622EJxxxx), FMEDA report, safety analysis summary, and diagnostic software library. All documents are qualified per TÜV SÜD certification and cover hardware metrics (SPFM ≥ 99%, LFM ≥ 90%) and systematic capability (SC3) for use in automotive safety-related systems.

Can the R7F7010303AFP-C#KA4 execute code directly from flash memory?

Yes, the R7F7010303AFP-C#KA4 supports XIP (eXecute-In-Place) from its 2 MB embedded flash memory with zero-wait-state operation at 200 MHz. Flash access uses a 128-bit prefetch buffer and dual-bank architecture to enable concurrent read/write operations, allowing safe firmware updates without halting CPU execution. ECC checking occurs transparently during each fetch cycle.

What is the role of the ICUMD module in the R7F7010303AFP-C#KA4?

The ICUMD (Intelligent Cryptographic Unit – Master D) in the R7F7010303AFP-C#KA4 is a dedicated hardware security engine that accelerates AES-128/256, SHA-256, RSA-2048, and ECC operations while protecting keys in tamper-resistant memory. It serves as the root of trust for secure boot, encrypted firmware updates, and TLS handshake offload-reducing CPU load by >95% compared to software-only implementations.
