It achieves 709 CoreMark performance and includes a single-precision IEEE 754 floating-point unit, barrel shifter, and 32×32→64-bit multiplier - all optimized for deterministic real-time control in industrial applications.

Does the R5F56604CDFB#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56604CDFB#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames with data rates up to 5 Mbps. It includes dedicated message RAM, error counters, and loopback/self-test modes - enabling robust communication in automotive and industrial networks without external transceivers.

What debug interfaces are available on the R5F56604CDFB#30?

The R5F56604CDFB#30 supports the FINE (single-wire) debug interface as standard. Unlike some variants in the RX660 Group (e.g., R5F56607CDFB#30), it does not include a JTAG interface. Debugging, flash programming, and real-time tracing are fully supported via FINE using Renesas E2 studio and CS+ toolchains.

How many analog-to-digital and digital-to-analog converter channels does the R5F56604CDFB#30 have?

The R5F56604CDFB#30 includes one 12-bit S12ADH analog-to-digital converter with 24 input channels and two 12-bit R12DAb digital-to-analog converter channels. Both DAC outputs can serve as reference voltages for the four-channel CMPC analog comparators - enabling precision threshold detection without external components.

Is the R5F56604CDFB#30 qualified for industrial temperature range and functional safety standards?

Yes, the R5F56604CDFB#30 is rated for the industrial temperature range of –40°C to +85°C (D-version) and includes hardware features required for IEC60730 Class B compliance: memory protection unit (MPU), clock oscillation stop detection, CRC calculator (CRCA), clock accuracy measurement circuit (CAC), and register write protection - validated in Renesas' functional safety documentation.
