For engineers reviewing the R5F56604CDFM#10 datasheet, R5F56604CDFM#10 pinout, R5F56604CDFM#10 application, or R5F56604CDFM#10 equivalent, key selection criteria include its 144-pin LFQFP package (PLQP0144KA-B), 2.7–5.5 V single-supply operation, IEC60730-ready features (oscillation-stop detection, RAM test assist, CRC calculator), and dual debugging interfaces (JTAG + FINE).

Technical Context

The R5F56604CDFM#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 combines an 8–24 MHz external main oscillator, 32.768 kHz sub-clock, and selectable on-chip oscillators (LOCO/HOCO/IWDT-dedicated), enabling independent domain clocks (ICLK up to 120 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz, ADCLK up to 60 MHz).

Peripheral integration includes MTU3a (9-channel 16/32-bit timer with complementary PWM and dead-time control), ELC for interrupt-free inter-module event linking, DMACA (8-channel DMA), DTC (1-channel data transfer controller), and safety-critical modules: CAC for clock accuracy monitoring, CRCA for 8/32-bit CRC generation, and DOCA for 32-bit arithmetic verification - all supporting IEC60730 Class B compliance.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56604CDFM#10?

The R5F56604CDFM#10 operates at a maximum system clock frequency of 120 MHz and achieves 709 CoreMark points at that speed. This performance level is enabled by the RXv3 CPU core's optimized pipeline, single-cycle instruction execution for most operations, and integrated 32-bit multiplier/divider. The R5F56604CDFM#10 sustains this throughput with zero-wait-state access to both 1 Mbyte code flash and 128 Kbytes SRAM - essential for deterministic real-time control loops.

Does the R5F56604CDFM#10 support CAN FD, and what standards does it comply with?

Yes, the R5F56604CDFM#10 includes one CAN FD module compliant with ISO 11898-1:2015, supporting both standard (11-bit) and extended (29-bit) frame formats at data rates up to 5 Mbps. It implements bit-rate switching, flexible data-length payloads (up to 64 bytes), and error confinement mechanisms required for automotive and industrial fieldbus applications. The R5F56604CDFM#10's CAN FD peripheral operates independently of CPU load via ELC-triggered message transmission and reception.

What analog peripherals are integrated into the R5F56604CDFM#10?

The R5F56604CDFM#10 integrates a 24-channel 12-bit S12ADH analog-to-digital converter with 0.9 μs minimum conversion time (at 60 MHz ADCLK), two 12-bit R12DAb digital-to-analog converters (0–AVCC0 output), and four-channel CMPC analog comparators. The ADC supports self-diagnosis, analog input disconnection detection, and group-scan prioritization; the DAC outputs can serve as precision references for the comparators. All analog blocks are calibrated and temperature-compensated for industrial-grade accuracy.

How does the R5F56604CDFM#10 support IEC60730 Class B compliance?

The R5F56604CDFM#10 provides hardware-level IEC60730 Class B support through integrated modules: Clock Accuracy Measurement Circuit (CAC) monitors oscillator drift, CRC Calculator (CRCA) validates memory integrity, Data Operation Circuit (DOCA) verifies arithmetic results, and register write protection prevents accidental corruption. Combined with MPU-enforced memory isolation and Trusted Memory (TM) for secure boot code, these features eliminate need for external safety monitors - enabling certified designs with the R5F56604CDFM#10 as the sole safety controller.

What package type and pin count does the R5F56604CDFM#10 use?

The R5F56604CDFM#10 uses a 144-pin Low-profile Quad Flat Package (LFQFP) with part code PLQP0144KA-B: 20 × 20 mm body, 0.5 mm pitch, exposed thermal pad, and RoHS compliance. This package supports 130 general-purpose I/O pins (including 4 with 5-V tolerance), JTAG and FINE debug interfaces, and full peripheral routing - including dedicated MTU3a waveform outputs, CAN FD transceiver pins, and 24 ADC input channels - making it the highest-pin-count variant in the RX660 family.
