FAQ

What is the maximum operating frequency and core architecture of the R5F56604CGFM#30?

The R5F56604CGFM#30 operates at a maximum frequency of 120 MHz using the 32-bit RXv3 CPU core with integrated single-precision floating-point unit (FPU) compliant with IEEE 754. It achieves 709 CoreMark performance and supports collective register bank save, memory protection unit (MPU), and 113 instruction set - making it suitable for demanding real-time control tasks. This specification is confirmed in Rev.1.00 of the R01DS0393EJ0100 datasheet.

Does the R5F56604CGFM#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56604CGFM#30 integrates one CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames at data rates up to 5 Mbps. The module includes message filtering, FIFO buffering, and error handling hardware - essential for deterministic communication in industrial networks. This capability is explicitly documented in Section 1.1 and Table 1.1 of the R01DS0393EJ0100 datasheet.

What are the analog capabilities of the R5F56604CGFM#30, and how are they applied in control systems?

The R5F56604CGFM#30 includes a 24-channel 12-bit S12ADH ADC (0.9 µs conversion time), two 12-bit R12DAb DAC outputs, and four CMPC analog comparators. The DAC outputs can serve as precision references for the comparators, enabling zero-crossing detection or overcurrent trip functions in motor drives. These features are validated in Tables 1.1 and 1.2 of the R01DS0393EJ0100 datasheet and support closed-loop analog signal conditioning without external components.

What debugging interfaces does the R5F56604CGFM#30 provide, and how do they differ from other RX660 variants?

The R5F56604CGFM#30 supports FINE (one-line) and JTAG debugging interfaces. However, per Table 1.2 of the R01DS0393EJ0100 datasheet, this specific part number omits the JTAG interface - confirming it is FINE-only. This distinguishes it from variants like R5F56607CGFM#30 (JTAG-enabled) and aligns with Renesas' packaging differentiation strategy for debug flexibility versus pin count optimization.

What is the operating temperature range and package type of the R5F56604CGFM#30?

The R5F56604CGFM#30 is rated for –40°C to +105°C (G-version) and housed in a 144-pin LFQFP package designated PLQP0144KA-B - measuring 20 × 20 mm with 0.5 mm pitch and an exposed thermal pad. This package supports high-density PCB layouts and thermal dissipation in industrial enclosures, as specified in Section 1.1 and Table 1.1 of the R01DS0393EJ0100 datasheet.
