Does the R7F702002AEABG-C#BC0 support JTAG debugging in lockstep mode?
Yes, the R7F702002AEABG-C#BC0 supports synchronized JTAG debugging across both cores via dedicated TRST/TCK/TMS/TDO/TDI pins. Debug access maintains lockstep integrity during halting and stepping operations, and the FCCU monitors debug activity for unauthorized access attempts. The R7F702002AEABG-C#BC0 also supports SWD for reduced pin count debugging while preserving safety-critical functionality.
What is the maximum operating frequency of the R7F702002AEABG-C#BC0?
The R7F702002AEABG-C#BC0 operates at a maximum CPU frequency of 240 MHz per core under automotive temperature conditions (–40°C to +125°C). This frequency is guaranteed with full ASIL-D safety mechanisms enabled, including ECC checking, FCCU monitoring, and lockstep comparison logic. The R7F702002AEABG-C#BC0 achieves deterministic real-time performance with worst-case interrupt latency under 100 µs.
How is Flash memory protected against corruption in the R7F702002AEABG-C#BC0?
The R7F702002AEABG-C#BC0 implements full ECC protection across its 2 MB on-chip Flash memory, detecting and correcting single-bit errors and detecting double-bit errors in real time. Flash programming includes checksum verification and write-protection registers enforced by the FCCU. The R7F702002AEABG-C#BC0 also supports background CRC scanning and automatic sector remapping upon unrecoverable error detection.
Can the R7F702002AEABG-C#BC0 be used in non-automotive applications?
The R7F702002AEABG-C#BC0 is qualified for automotive use (AEC-Q100 Grade 1) and designed for ASIL-D safety-critical systems; it is not recommended for consumer or industrial applications where cost, power, or feature set are primary constraints. While functionally capable in non-automotive contexts, its safety infrastructure, temperature range, and qualification data are optimized for automotive powertrain and chassis control. Use of the R7F702002AEABG-C#BC0 outside automotive applications requires full re-qualification per end-equipment standards.
