Overview

R5F56604BGFM#30 from Renesas is a 32-bit RXv3 microcontroller operating at up to 120 MHz, featuring 1 MB code flash, 128 KB SRAM, 32 KB data flash, CAN FD interface, 12-bit A/D and D/A converters, real-time clock with sub-clock oscillator support, and IEC60730 safety features for industrial control applications.

For engineers reviewing the R5F56604BGFM#30 datasheet, R5F56604BGFM#30 pinout, R5F56604BGFM#30 application, or R5F56604BGFM#30 equivalent, this MCU delivers deterministic real-time performance, integrated functional safety peripherals (MPU, IWDT, CAC, CRCA), and flexible low-power operation across –40°C to +105°C ambient conditions.

Technical Context

The R5F56604BGFM#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, 16 register banks for fast context switching, and memory protection unit (MPU) supporting eight configurable regions down to 16-byte granularity. It integrates Trusted Memory (TM) for secure code execution in the flash target area.

Its clock system combines an 8–24 MHz external main oscillator, 32.768 kHz sub-clock oscillator (required for RTC), and selectable on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PLL and fine-grained peripheral clock dividers (PCLKA/PCLKB/PCLKD/FCLK/BCLK) enabling mixed-speed operation - e.g., MTU3a and RSPI running at 120 MHz while S12ADH operates at 60 MHz ADCLK.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56604BGFM#30?

The R5F56604BGFM#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark in benchmark testing. This performance stems from its RXv3 CPU core architecture with single-cycle instruction execution, on-chip 32-bit multiplier/divider, and barrel shifter - all validated under the conditions specified in the R01DS0393EJ0100 datasheet Rev.1.00.

Does the R5F56604BGFM#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56604BGFM#30 integrates a CAN FD module compliant with ISO 11898-1:2015, supporting both standard and extended frames. It operates at data rates up to 5 Mbps in FD mode and maintains full backward compatibility with classical CAN 2.0B networks - confirmed in Section 1.1 and Table 1.1 of the official datasheet.

What package type and pin count does the R5F56604BGFM#30 use?

The R5F56604BGFM#30 uses the PLQP0144KA-B package: a 144-pin Low-profile Quad Flat Package with 20 × 20 mm body size, 0.5 mm pitch, and exposed thermal pad. This matches the "144-pin LFQFP with JTAG interface and sub-clock oscillator" configuration detailed in Table 1.2 of the R01DS0393EJ0100 datasheet.

Is the real-time clock (RTC) functional on the R5F56604BGFM#30, and what oscillator does it require?

Yes, the RTC is fully functional on the R5F56604BGFM#30 and requires connection of a 32.768 kHz crystal to XT1/XT2 pins. The device belongs to the "144-pin LFQFP with JTAG interface and sub-clock oscillator" variant, which explicitly supports RTC operation per Table 1.2 - unlike smaller packages where SOSC is omitted.

What safety certifications or built-in features does the R5F56604BGFM#30 support for IEC60730 compliance?

The R5F56604BGFM#30 includes dedicated hardware for IEC60730 Class B compliance: memory protection unit (MPU), independent watchdog timer (IWDT) with windowing, clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA), data operation circuit (DOCA), and register write protection. These are documented in Section 1.1 and Chapter 27 of the R01DS0393EJ0100 datasheet.

Does the R5F56604BGFM#30 include a floating-point unit (FPU), and what standard does it follow?

Yes, the R5F56604BGFM#30 integrates a single-precision (32-bit) floating-point unit compliant with the IEEE 754 standard. It supports basic arithmetic operations, exceptions, and data types as defined in the specification - confirmed in Table 1.1 "FPU" section and Section 1.1 of the R01DS0393EJ0100 datasheet.
