Overview

R5F56604DDFM#10 from Renesas Electronics is a 32-bit RXv3 microcontroller operating at up to 120 MHz, featuring 1 MB code flash, 128 KB SRAM, 32 KB data flash, integrated CAN FD, 12-bit A/D and D/A converters, and real-time clock with sub-clock oscillator support - deployed in industrial motor control, building automation, and smart metering systems requiring deterministic timing and IEC 60730 compliance.

For engineers reviewing the R5F56604DDFM#10 datasheet, R5F56604DDFM#10 pinout, R5F56604DDFM#10 application, or R5F56604DDFM#10 equivalent, this page delivers verified specifications, package mapping to PLQP0144KA-B (144-pin LFQFP), functional pin roles, IEC 60730 self-test features, CAN FD protocol conformance per ISO 11898-1:2015, and validated alternative MCU options for migration or second sourcing.

Technical Context

The R5F56604DDFM#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, 16 register banks for fast context switching, and memory protection unit (MPU) supporting eight configurable protection areas down to 16-byte granularity. It integrates Trusted Memory (TM) for secure code execution and register write protection to prevent unintended overwrites during fault conditions.

Its clock system combines an 8–24 MHz external main oscillator, 32.768 kHz sub-clock oscillator, and selectable on-chip oscillators (LOCO/HOCO/IWDT-dedicated), enabling independent domain clocking: ICLK up to 120 MHz, PCLKA up to 120 MHz (for MTU/RSPI/SCI10–11), PCLKB up to 60 MHz (for TMR/CMT/CMTW), and ADCLK up to 60 MHz for the S12ADH A/D converter - all managed via programmable PLL and frequency dividers.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56604DDFM#10?

The R5F56604DDFM#10 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark under those conditions. This performance stems from the RXv3 CPU core's single-cycle instruction execution, collective register bank save function, and optimized memory subsystem - all confirmed in the official R01DS0393EJ0100 datasheet Rev.1.00. The R5F56604DDFM#10 sustains this speed with zero wait states on both 1 MB code flash and 128 KB SRAM.

Does the R5F56604DDFM#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56604DDFM#10 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames at data rates up to 5 Mbps. This is explicitly stated in the "Features" section and Table 1.1 of the R01DS0393EJ0100 datasheet. The R5F56604DDFM#10 implements full protocol handling including bit rate switching and flexible data length - essential for modern industrial and automotive diagnostics networks.

What package type and pin count does the R5F56604DDFM#10 use?

The R5F56604DDFM#10 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package with 20 × 20 mm body size and 0.5 mm pitch. This is unambiguously specified in the "Package" section of the R01DS0393EJ0100 datasheet (page 9) and confirmed in Table 1.2 for the RX660 Group. The part number suffix "FM" directly maps to this 144-pin LFQFP variant.

Does the R5F56604DDFM#10 include a real-time clock (RTC), and what oscillator does it require?

Yes, the R5F56604DDFM#10 includes a real-time clock (RTCC) module, but its operation requires the sub-clock oscillator (SOSC) connected to a 32.768 kHz crystal - as noted in datasheet Notes 1 and 2 on pages 9 and 10. The R5F56604DDFM#10's 144-pin package supports SOSC, enabling calendar/timekeeping, alarm interrupts, and time-capture functionality even in deep software standby mode.

What IEC 60730 safety features are implemented in the R5F56604DDFM#10?

The R5F56604DDFM#10 implements multiple IEC 60730 Class B compliance features: oscillation-stoppage detection for main/sub clocks, A/D converter self-diagnosis and analog input disconnection detection, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), RAM test assist via Data Operation Circuit (DOCA), and register write protection. These are documented in the "Useful functions for IEC60730 compliance" section of the R01DS0393EJ0100 datasheet.
