The R5F56604FDFP#30 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 multiplier, and hardware FPU. The R5F56604FDFP#30 sustains this performance with zero-wait-state access to both 1 Mbyte code flash and 128 Kbyte SRAM at full speed.

Does the R5F56604FDFP#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56604FDFP#30 includes one CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames. It enables data rates up to 5 Mbps in the FD data phase while maintaining backward compatibility with classical CAN. The module integrates message RAM, error counters, and flexible filtering - all accessible via the RSCAN peripheral registers in the R5F56604FDFP#30 hardware manual.

What package type and pin count does the R5F56604FDFP#30 use?

The R5F56604FDFP#30 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with designation PLQP0144KA-B: 20 × 20 mm body, 0.5 mm lead pitch, and exposed thermal pad. This package includes JTAG and FINE debug interfaces, sub-clock oscillator pins (XT1/XT2), and supports all 130 GPIOs, 24 ADC channels, and dual DAC outputs specified for the RX660 Group's 144-pin variant.

How does the R5F56604FDFP#30 support IEC 60730 functional safety compliance?

The R5F56604FDFP#30 integrates multiple hardware features for IEC 60730 Class B: memory protection unit (MPU), Trusted Memory (TM) for code protection, CRC calculator (CRCA), clock accuracy measurement circuit (CAC), oscillation-stop detection, register write protection, and data operation circuit (DOCA). These reduce software certification burden by providing deterministic, hardware-enforced safety mechanisms directly within the R5F56604FDFP#30 silicon.

What are the key differences between the R5F56604FDFP#30 and R5F56605FDFP#30?
