Renesas R5F56609CDFM#30

Overview

R5F56609CDFM#30 from Renesas is a 32-bit RXv3 microcontroller operating at up to 120 MHz, featuring 1 Mbyte of on-chip code flash, 128 Kbytes of 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-critical embedded systems requiring IEC60730 compliance, real-time responsiveness, and mixed-signal integration.

For engineers reviewing the R5F56609CDFM#30 datasheet, R5F56609CDFM#30 pinout, R5F56609CDFM#30 application, or R5F56609CDFM#30 equivalent, key selection criteria include its 144-pin LFQFP (PLQP0144KA-B) package, dual D/A output capability, sub-clock oscillator support for RTC, JTAG+FINE debug interface, and full CAN FD compliance per ISO 11898-1:2015.

Technical Context

The R5F56609CDFM#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 functions.

Peripheral coordination is managed via the Event Link Controller (ELC), which enables 83 internal event signals to trigger module operations (e.g., MTU3a PWM start, S12ADH conversion) without CPU intervention - critical for deterministic low-latency response in motor control and real-time monitoring applications.
