Renesas R5F56609GDFB#10

Overview

R5F56609GDFB#10 from Renesas is a 120-MHz 32-bit RXv3 microcontroller with integrated FPU, 1 Mbyte code flash, 128 Kbytes SRAM, and 32 Kbytes data flash. It features CAN FD (ISO 11898-1:2015), 12-bit A/D and D/A converters, RTC with sub-clock support, and operates from 2.7–5.5 V across –40°C to +105°C. It targets industrial motor control and safety-critical embedded systems requiring IEC60730 compliance.

For engineers reviewing the R5F56609GDFB#10 datasheet, R5F56609GDFB#10 pinout, R5F56609GDFB#10 application, or R5F56609GDFB#10 equivalent, key selection criteria include its 144-pin LFQFP (PLQP0144KA-B) package, JTAG/FINE debug interfaces, 134 general-purpose I/O pins with 5-V tolerance, and full peripheral set including MTU3a, ELC, and Trusted Memory (TM) protection.

Technical Context

The R5F56609GDFB#10 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16 register banks for fast context switching. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent IWDT-dedicated 120-kHz oscillator - enabling precise timing control and fail-safe watchdog operation.

Peripheral coordination is handled by the Event Link Controller (ELC), which supports 83 internal event signals for interrupt-free module interoperation (e.g., MTU-triggered A/D conversion, RTC time capture on GPIO edge). The MCU includes hardware-accelerated safety functions: CAC for clock accuracy monitoring, CRCA with configurable polynomials, DOCA for 32-bit arithmetic verification, and MPU with eight 16-byte granular protection regions.

FAQ

What is the maximum operating frequency and CPU architecture of the R5F56609GDFB#10?

The R5F56609GDFB#10 operates at a maximum frequency of 120 MHz using the 32-bit RXv3 CPU core. It delivers 709 CoreMark performance and includes a single-precision IEEE 754 floating-point unit (FPU), collective register bank save, and memory protection unit (MPU). The core supports 113 instructions, 11 addressing modes, and deterministic single-cycle execution for real-time determinism.

Does the R5F56609GDFB#10 support CAN FD, and what standard does it comply with?

Yes, the R5F56609GDFB#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. It includes built-in protocol handling, error confinement, and message buffering - eliminating need for external CAN transceivers beyond physical layer drivers. This makes R5F56609GDFB#10 suitable for automotive diagnostics and industrial fieldbus applications requiring high-speed deterministic communication.

What safety certifications and hardware features does the R5F56609GDFB#10 provide for IEC60730 compliance?

The R5F56609GDFB#10 includes dedicated hardware for IEC60730 Class B compliance: clock frequency accuracy measurement circuit (CAC), CRC calculator (CRCA) with configurable polynomials, data operation circuit (DOCA), memory protection unit (MPU), register write protection, and oscillation-stop detection. These features enable runtime self-tests of flash, RAM, clocks, A/D, and comparators - reducing certified software effort and simplifying functional safety certification for household and industrial appliances.

What is the package type and pin count of the R5F56609GDFB#10, and does it support 5-V tolerant I/O?

The R5F56609GDFB#10 uses a 144-pin LFQFP package (PLQP0144KA-B, 20 × 20 mm, 0.5 mm pitch) and provides 134 general-purpose I/O pins. Four of these pins are 5-V tolerant, supporting mixed-voltage interfacing with legacy 5-V peripherals. All I/Os support pull-up resistors, open-drain output, and configurable drive strength - enabling direct connection to sensors, displays, and industrial I/O without level-shifting components.

How does the Event Link Controller (ELC) enhance real-time performance in the R5F56609GDFB#10?

The Event Link Controller (ELC) in the R5F56609GDFB#10 enables hardware-level chaining of 83 internal peripheral events - such as MTU3a overflow triggering A/D conversion, which then initiates DMACA transfer - without CPU or interrupt latency. This offloads deterministic timing-critical sequences from firmware, improves system responsiveness, and reduces power consumption by allowing deeper sleep modes during background operations.
