It integrates 1 MB code flash, 128 KB SRAM, 32 KB data flash, CAN FD interface, 12-bit A/D and D/A converters, RTC with sub-clock support, and operates from 2.7–5.5 V in industrial temperature range (–40°C to +105°C). It targets real-time motor control and industrial automation systems requiring functional safety compliance.

For engineers reviewing the R5F56604DGFB#30 datasheet, R5F56604DGFB#30 pinout, R5F56604DGFB#30 application, or R5F56604DGFB#30 equivalent, key selection criteria include its 144-pin LFQFP package with JTAG/FINE debug, 120-MHz deterministic timing, IEC60730-ready self-test features, and integrated analog peripherals enabling single-chip sensor-to-actuator control in safety-critical embedded designs.

Technical Context

The R5F56604DGFB#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant FPU, and 16 register banks for fast context switching. Its clock system combines an 8–24 MHz external main oscillator, 32.768 kHz sub-clock, and selectable on-chip oscillators (LOCO/HOCO/IWDT), all feeding independent PLL and peripheral clock domains (ICLK up to 120 MHz, PCLKA/B/D up to 120/60/60 MHz).

Peripheral integration includes MTU3a (9-channel PWM/timer), ELC for interrupt-free inter-module triggering, S12ADH (24-channel 12-bit ADC with disconnection detection), R12DAb (2-channel DAC usable as comparator reference), CMPC (4-channel analog comparator), and CAN FD compliant with ISO 11898-1:2015 - all accessible via 130 GPIO pins with 5-V tolerance, open-drain, and pull-up options in the PLQP0144KA-B package.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56604DGFB#30?

The R5F56604DGFB#30 operates at a maximum frequency of 120 MHz and achieves 709 CoreMark performance. This score reflects deterministic execution of the EEMBC benchmark under real-world conditions, enabled by the RXv3 core's single-cycle instruction execution, zero-wait-state 1 MB flash, and 128 KB SRAM - all verified in Renesas' R01DS0393EJ0100 datasheet.

Does the R5F56604DGFB#30 support CAN FD, and what standard does it comply with?

Yes, the R5F56604DGFB#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 phase and maintains backward compatibility with classical CAN networks - confirmed in Section 1.1 and Table 1.1 of the R01DS0393EJ0100 datasheet.

What package type and pin count does the R5F56604DGFB#30 use?

The R5F56604DGFB#30 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 variant includes JTAG and sub-clock oscillator support, providing 130 general-purpose I/O pins - as specified in Table 1.2 and package dimension diagrams of R01DS0393EJ0100.

How does the R5F56604DGFB#30 support IEC60730 functional safety compliance?

The R5F56604DGFB#30 integrates multiple IEC60730 Class B features: oscillation-stop detection, A/D disconnection monitoring, clock frequency accuracy measurement (CAC), CRC calculator (CRCA), RAM test assist (DOC), and register write protection. These are documented in Section 1.1 "Useful functions for IEC60730 compliance" of R01DS0393EJ0100 and validated for use in safety-critical firmware.

What are the supported clock sources and their roles in the R5F56604DGFB#30?

The R5F56604DGFB#30 supports multiple clock sources: 8–24 MHz external main oscillator (for PLL reference), 32.768 kHz sub-clock (for RTC), internal LOCO (240 kHz), selectable HOCO (16/18/20 MHz), and IWDT-dedicated oscillator (120 kHz). Each feeds distinct clock domains (ICLK, PCLKA/B/D, FCLK, BCLK) - detailed in Section 1.1 "Clock generation circuit" of R01DS0393EJ0100.
