Technical Context

The R5F56604CDFP#10 implements the RXv3 CPU core with single-precision FPU compliant with IEEE 754, 16 register banks for fast context switching, and MPU-based memory protection. Its clock system includes main (8–24 MHz crystal), sub-clock (32.768 kHz), and on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PLL and frequency-division paths for ICLK (up to 120 MHz), PCLKA (up to 120 MHz), PCLKB (up to 60 MHz), and ADCLK (up to 60 MHz).

Peripheral integration centers on event-driven architecture via the ELC, enabling inter-module triggering without CPU intervention. It supports CAN FD (ISO 11898-1:2015), up to 13 SCI channels with flexible modes (asynchronous, SPI/I²C emulation), RSPI (30 Mbps), RIIC (400 kbps), and MTU3a with complementary PWM for 3-phase inverter control - including dead-time compensation and synchronous A/D trigger generation.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56604CDFP#10?

The R5F56604CDFP#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing at that speed. This performance stems from the RXv3 CPU core's efficient pipeline, zero-wait-state 1 Mbyte code flash, and integrated single-precision FPU - enabling computationally intensive tasks like motor control algorithms and sensor fusion without external co-processors. The R5F56604CDFP#10 sustains this throughput across its full operating voltage range (2.7–5.5 V) and temperature range (–40°C to +85°C).

Does the R5F56604CDFP#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56604CDFP#10 includes one CAN FD module compliant with ISO 11898-1:2015, supporting both standard (11-bit) and extended (29-bit) frame formats. It enables data rates up to 5 Mbps in the FD data phase while maintaining backward compatibility with classical CAN networks. The R5F56604CDFP#10's CAN FD implementation includes message filtering, transmit/receive FIFOs, and error handling - making it suitable for real-time industrial communication where bandwidth and deterministic latency are critical.

What are the analog capabilities of the R5F56604CDFP#10, particularly regarding ADC and DAC?

The R5F56604CDFP#10 integrates a 24-channel 12-bit S12ADH ADC with minimum 0.9 µs conversion time (at 60 MHz ADCLK), and two independent 12-bit R12DAb DAC channels with 0–AVCC0 output range. Crucially, the DAC outputs can serve as reference voltages for the four-channel CMPC analog comparators - enabling precision window-comparison monitoring of sensor signals. These analog resources are fully supported in the 144-pin package and operate across the full industrial temperature range without calibration drift.

How does the R5F56604CDFP#10 support functional safety standards like IEC60730?

The R5F56604CDFP#10 incorporates multiple hardware features certified for Class B compliance per IEC60730: oscillation-stop detection for main/sub clocks, CRC calculator (CRCA) for memory and data integrity, register write protection to prevent accidental corruption, independent watchdog timer (IWDT) with windowing, and self-diagnostic A/D converter functions. These are complemented by Trusted Memory (TM) for secure firmware storage and DOCA for runtime data validation - all documented in Renesas' Functional Safety Manual for the RX660 Group. The R5F56604CDFP#10 requires no external safety monitors for basic Class B implementations.

What package type and pin count does the R5F56604CDFP#10 use, and is it RoHS compliant?

The R5F56604CDFP#10 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package measuring 20 × 20 mm with 0.5 mm lead pitch and an exposed thermal pad. It is RoHS compliant and rated for industrial operation from –40°C to +85°C. This package provides full access to all RX660 Group peripherals - including 133 GPIOs (with 4× 5-V tolerant pins), dual DAC outputs, CAN FD, and all 13 SCI channels - making it the highest-density option in the RX660 family. The R5F56604CDFP#10's pinout is fully documented in Section 1.2 of the R01DS0393EJ0100 datasheet.
