Product details
Overview
R5F572MNDDBG#20 from Renesas is a 32-bit RXv3 microcontroller optimized for industrial real-time control with EtherCAT slave capability, operating at up to 240 MHz and delivering 1396 CoreMark. It integrates 2 Mbytes of on-chip code flash, 1 Mbyte of SRAM (including 32 Kbytes with ECC), dual-bank flash architecture, IEEE-754 double-precision FPU, and hardware-accelerated trigonometric functions - deployed in motion control systems requiring deterministic Ethernet-based synchronization.
For engineers reviewing the R5F572MNDDBG#20 datasheet, R5F572MNDDBG#20 pinout, R5F572MNDDBG#20 application, or R5F572MNDDBG#20 equivalent, key selection criteria include EtherCAT slave controller compliance, IEEE 1588 PTP timing precision, dual-bank flash for safe firmware updates, 240-MHz real-time execution, and integrated delta-sigma modulator interface supporting six external ΣΔ ADCs.
Technical Context
The R5F572MNDDBG#20 implements the RXv3 CPU core with full IEEE-754 double-precision floating-point unit and collective register bank save for fast context switching. Its clock system supports independent domain scaling: ICLK up to 240 MHz for CPU execution, PCLKA up to 120 MHz for peripherals like ETHERC and ESC, and PCLKB up to 60 MHz for timers and serial interfaces.
Real-time determinism is enforced via hardware co-processors: EtherCAT Slave Controller (ESC) with two physical ports, IEEE 1588-compliant EPTPC module for sub-microsecond timestamping, and event-link controller (ELC) enabling direct peripheral-to-peripheral triggering without CPU intervention - critical for synchronized multi-axis motor control loops.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar industrial real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F572MNDKBD#20 | Same RX72M core, but 4 Mbyte flash and PLBG0224GA-A 224-pin BGA package - adds 2 Mbyte code capacity and 46 additional I/Os. | Better suited for complex HMI-integrated drives requiring large GUI assets and expanded peripheral connectivity. | Select when firmware size exceeds 2 Mbyte or >136 GPIOs are needed; not pin-compatible due to BGA vs LQFP packaging. |
| R5F566TKEDDFP#30 | RX66T group MCU: 160 MHz max, no EtherCAT slave controller, no EPTPC, but higher CAN channel count (5) and larger 32 Kbyte data flash. | Targeted at standalone motor control without deterministic Ethernet - e.g., single-axis inverters using CANopen or Modbus TCP. | Choose for cost-sensitive non-networked drives where EtherCAT/PTP are unnecessary; requires PCB redesign due to different pinout and package (144-pin LQFP). |
Compared with R5F572MNDKBD#20, the R5F572MNDDBG#20 trades flash capacity and I/O count for LQFP manufacturability and lower assembly cost; versus R5F566TKEDDFP#30, it delivers deterministic EtherCAT synchronization essential for coordinated multi-axis systems but at higher unit cost and power consumption.
