FAQ

What is the maximum operating frequency and CoreMark score of the R5F56604HGFB#10?

The R5F56604HGFB#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This benchmark reflects its RXv3 CPU core efficiency, including single-cycle instruction execution, 32×32→64-bit hardware multiplier, and IEEE 754-compliant floating-point unit. The R5F56604HGFB#10 sustains this performance with zero-wait-state access to both 1 Mbyte code flash and 128 Kbyte SRAM, enabling deterministic real-time execution critical for motor control loops.

Does the R5F56604HGFB#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56604HGFB#10 integrates one CAN FD module compliant with ISO 11898-1:2015, supporting both standard (11-bit) and extended (29-bit) frame formats. It delivers data rates up to 5 Mbps in the flexible data phase, with built-in error confinement, bit-rate switching, and CRC protection. This capability makes the R5F56604HGFB#10 suitable for high-bandwidth industrial fieldbus applications where legacy CAN 2.0B throughput is insufficient.

What are the analog capabilities of the R5F56604HGFB#10, and how are they used together?

The R5F56604HGFB#10 includes a 24-channel 12-bit S12ADH ADC, two 12-bit R12DAb D/A converters, and four CMPC analog comparators. The D/A outputs can serve as precision reference voltages for the comparators, enabling window-comparison monitoring of sensor signals. Simultaneously, the ADC supports ELC-triggered sampling synchronized to MTU timer events-critical for accurate current sensing in motor control. All analog blocks share the same AVCC0 supply domain and benefit from on-chip temperature sensor calibration.

How does the R5F56604HGFB#10 support functional safety standards like IEC60730?

The R5F56604HGFB#10 includes multiple hardware features for IEC60730 Class B compliance: oscillation-stop detection for main/sub clocks, clock frequency accuracy measurement circuit (CAC), RAM test-assist function via DOC, CRC calculator (CRCA) for memory/data integrity, independent watchdog timer (IWDTa) with windowing, and register write protection. These eliminate the need for external safety monitors in many industrial control designs, reducing BOM cost and board space while maintaining diagnostic coverage >90%.

What debugging interfaces does the R5F56604HGFB#10 provide, and are they compatible with standard tools?

The R5F56604HGFB#10 supports both JTAG (IEEE 1149.1) and FINE (one-wire) debugging interfaces. JTAG enables full-speed SWD-style tracing, flash programming, and boundary-scan testing using standard Renesas E2 studio, IAR Embedded Workbench, or SEGGER J-Link tools. FINE provides minimal-pin debugging for space-constrained layouts. Both interfaces support real-time variable watch, breakpoint insertion, and memory inspection-essential for validating complex motor control algorithms on the R5F56604HGFB#10.
