Renesas R5F572MNDDFC#30

Overview

R5F572MNDDFC#30 from Renesas is a 32-bit RXv3 microcontroller operating at 240 MHz, featuring double-precision IEEE-754 FPU, 2 Mbytes of on-chip code flash, 1 Mbyte of SRAM (512 KB standard + 512 KB expansion), and integrated EtherCAT slave controller with two ports. It targets industrial motion control systems requiring deterministic real-time Ethernet, high-precision analog acquisition, and secure firmware execution.

For engineers reviewing the R5F572MNDDFC#30 datasheet, R5F572MNDDFC#30 pinout, R5F572MNDDFC#30 application, or R5F572MNDDFC#30 equivalent, key selection criteria include EtherCAT slave timing compliance, dual-bank flash for safe firmware updates, 12-bit A/D converter channel count (29 total), 240-MHz CPU performance with 1396 CoreMark, and support for IEC60730 Class B safety certification functions.

Technical Context

The R5F572MNDDFC#30 implements the RXv3 CPU core with hardware-accelerated double-precision floating-point arithmetic, collective register bank save for fast interrupt response, and memory protection unit (MPU) for task isolation. Its clock architecture supports independent domain clocks - ICLK up to 240 MHz for CPU, PCLKA up to 120 MHz for Ethernet/ESC/GPTW, and PCLKB up to 60 MHz for timers and peripherals.

Real-time capability is reinforced by dedicated hardware: EtherCAT Slave Controller (ESC) compliant with Beckhoff IP core, IEEE 1588 PTP module (EPTPC), three CAN channels (32 mailboxes each), and event-link controller (ELC) enabling zero-CPU-latency peripheral synchronization. Safety is addressed via oscillation-stop detection, CRC accelerators, IWDT with window function, and A/D self-diagnostic features.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F572MNDDFC#30?

The R5F572MNDDFC#30 operates at a maximum frequency of 240 MHz and achieves 1396 CoreMark. This performance level enables complex real-time control algorithms, such as field-oriented control (FOC) for servo motors, to execute within tight timing constraints while maintaining low jitter. The RXv3 core's instruction set and pipeline design contribute directly to this benchmark result.

Does the R5F572MNDDFC#30 include an integrated EtherCAT slave controller?

Yes, the R5F572MNDDFC#30 integrates a Beckhoff-certified EtherCAT Slave Controller (ESC) with two physical ports. This eliminates the need for external ASICs or PHYs, reducing system cost and board space. The ESC supports full EtherCAT slave functionality including process data exchange, distributed clocks, and DC synchronization - all verified per EtherCAT conformance testing requirements.

What flash and RAM configurations does the R5F572MNDDFC#30 provide?

The R5F572MNDDFC#30 includes 2 Mbytes of on-chip code flash memory with dual-bank architecture and 1 Mbyte of SRAM (512 KB standard + 512 KB expansion). It also features 32 KB of ECC-protected RAM and 8 KB of standby RAM. These resources support robust firmware partitioning, real-time data buffering, and fail-safe operation in industrial environments.

Which analog-to-digital converter resources are available on the R5F572MNDDFC#30?

The R5F572MNDDFC#30 integrates two independent 12-bit A/D converters: S12AD0 with 8 channels and S12AD1 with 21 channels, totaling 29 analog inputs. Both units support self-diagnosis, analog input disconnection detection, and simultaneous sampling - making them ideal for high-fidelity current/voltage sensing in multi-axis motor drives.

What safety features does the R5F572MNDDFC#30 offer for IEC60730 compliance?

The R5F572MNDDFC#30 includes multiple hardware features for IEC60730 Class B compliance: oscillation-stoppage detection, CRC accelerator (CRCA), independent watchdog timer (IWDT) with window function, self-diagnostic A/D converter test, and register write protection. These are documented in Renesas' RX72M Functional Safety Manual (R01UM0137EJ0100) and validated for use in safety-critical industrial control applications.
