FAQ

What is the maximum operating frequency and CoreMark score of the R5F56604CGFP#30?

The R5F56604CGFP#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark under benchmark conditions. This performance stems from the RXv3 CPU core's optimized pipeline, single-cycle instruction execution, and integrated FPU - enabling deterministic real-time processing for demanding control algorithms without external co-processors. The R5F56604CGFP#30 sustains this speed across its full voltage and temperature range.

Does the R5F56604CGFP#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56604CGFP#30 integrates one CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames with data rates up to 5 Mbps. It includes bit-rate switching, flexible data-length payloads (up to 64 bytes), and built-in error counters and filtering - making the R5F56604CGFP#30 suitable for automotive body networks and industrial real-time control where legacy CAN bandwidth is insufficient.

What are the memory resources available on the R5F56604CGFP#30?

The R5F56604CGFP#30 includes 1 Mbyte of on-chip code flash memory with zero-wait-state access at 120 MHz, 32 Kbytes of reprogrammable data flash (rated for 100,000 erase/write cycles), and 128 Kbytes of SRAM with no wait states. These resources support complex firmware with dual-bank OTA updates, persistent parameter storage, and real-time data buffering - all managed by the R5F56604CGFP#30's background operation capability.

Is the R5F56604CGFP#30 qualified for extended temperature operation?

Yes, the R5F56604CGFP#30 is the G-version part, rated for operation from –40°C to +105°C. This qualification meets industrial and under-hood automotive requirements, and is enabled by Renesas' high-temperature process and on-die thermal sensor calibrated to ±1.0°C accuracy - ensuring reliable R5F56604CGFP#30 operation in sealed enclosures, motor drives, and outdoor equipment.

What debugging interfaces does the R5F56604CGFP#30 support?

The R5F56604CGFP#30 supports both JTAG (IEEE 1149.1) and FINE (single-wire) debugging interfaces. JTAG enables full boundary-scan, real-time trace, and flash programming; FINE provides minimal-pin debugging for space-constrained layouts. Both interfaces are active simultaneously and support breakpoints, watchpoints, and memory inspection - essential for efficient development and validation of the R5F56604CGFP#30 in safety-critical applications.
