Renesas R5F56609BDFN#30

Overview

R5F56609BDFN#30 from Renesas is a 32-bit RXv3 microcontroller with 120 MHz maximum operating frequency, 1 Mbyte on-chip code flash, 128 Kbytes SRAM, and integrated CAN FD, 12-bit A/D and D/A converters, RTC, and hardware FPU. It targets industrial control, motor drive, and safety-compliant embedded systems requiring deterministic real-time performance and IEC60730 support.

For engineers reviewing the R5F56609BDFN#30 datasheet, R5F56609BDFN#30 pinout, R5F56609BDFN#30 application, or R5F56609BDFN#30 equivalent, key selection criteria include its 144-pin LFQFP (PLQP0144KA-B) package, JTAG/FINE debug interface, sub-clock oscillator inclusion, full peripheral set (including all 24 A/D channels and dual D/A), and D-version temperature rating (–40°C to +85°C).

Technical Context

The R5F56609BDFN#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16-register bank save for fast context switching. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent IWDT-dedicated 120-kHz oscillator - enabling precise timing isolation for safety-critical functions.

Peripheral coordination is managed via the Event Link Controller (ELC), which supports 83 internal event signals for interrupt-free inter-module triggering (e.g., MTU3a PWM sync to S12ADH conversion start). The MCU includes MPU-based memory protection, Trusted Memory (TM) for code flash read protection, and hardware CRC (CRCA), DOCA, and CAC circuits for IEC60730 Class B compliance.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F56609BDFN#30?

The R5F56609BDFN#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, 32-bit multiplier/divider, barrel shifter, and integrated single-precision floating-point unit - all verified in the official Renesas datasheet R01DS0393EJ0100.

Does the R5F56609BDFN#30 include a sub-clock oscillator and real-time clock (RTCC)?

Yes, the R5F56609BDFN#30 includes both a sub-clock oscillator (SOSCI/SOSCO pins) and the RTCC module. As confirmed in Table 1.2 of the datasheet, 144-pin packages with JTAG interface - like the R5F56609BDFN#30 - support RTCC functionality when a 32.768 kHz crystal is connected. The RTCC provides calendar/time counting, alarm, periodic interrupts, and time capture.

How many analog-to-digital and digital-to-analog converter channels does the R5F56609BDFN#30 support?

The R5F56609BDFN#30 integrates one 12-bit S12ADH analog-to-digital converter with 24 input channels and two 12-bit R12DAb digital-to-analog converter channels. This configuration is specific to 144-pin RX660 variants with JTAG and sub-clock oscillator - documented in Table 1.2 and Section 1.1 of the R01DS0393EJ0100 datasheet.

Is CAN FD supported on the R5F56609BDFN#30, and what standard does it comply with?

Yes, the R5F56609BDFN#30 includes 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, and applies to all RX660 Group devices with CANFD in the part number suffix.

What debugging interfaces are available on the R5F56609BDFN#30?

The R5F56609BDFN#30 supports both JTAG (IEEE 1149.1) and FINE (single-wire) debugging interfaces. The presence of JTAG is confirmed by the "BDFN" package code (144-pin LFQFP with JTAG) in Table 1.3 of the datasheet, and both interfaces enable full-featured programming, real-time trace, and non-intrusive debugging of the R5F56609BDFN#30.
