Product details
Overview
R5F572MDDGBD#20 from Renesas is a 32-bit RXv3 microcontroller with 240 MHz CPU, dual-bank 4 MB code flash, 1 MB SRAM (512 KB + 512 KB expansion), integrated EtherCAT slave controller, IEEE 1588-compliant Ethernet MAC, and 12-bit A/D converter - deployed in industrial motion control systems requiring real-time deterministic communication and high-precision analog acquisition.
For engineers reviewing the R5F572MDDGBD#20 datasheet, R5F572MDDGBD#20 pinout, R5F572MDDGBD#20 application, or R5F572MDDGBD#20 equivalent, key selection criteria include EtherCAT slave timing compliance, dual-bank flash for safe firmware updates, 240-MHz deterministic execution, IEEE 1588 timestamping accuracy, and 182-pin LFBGA package thermal and routing constraints.
Technical Context
The R5F572MDDGBD#20 implements the RXv3 CPU core with double-precision IEEE-754 FPU, 16 register banks for fast context switching, and MPU-based memory protection - enabling safety-critical IEC 60730-certifiable firmware. Its clock system integrates PLLs for 240 MHz ICLK, independent PCLKA/PCLKB domains (120/60 MHz), and dedicated IWDT oscillator for fail-safe watchdog operation.
Peripheral integration centers on deterministic real-time I/O: EtherCAT slave controller (two ports), dual-channel Ethernet MAC with EPTPC for hardware timestamping, 3-channel CAN with 32 mailboxes per channel, and DSMIF supporting six external delta-sigma modulators - all coordinated via Event Link Controller (ELC) to minimize CPU intervention in time-critical signal chains.

Equivalent & Alternatives
The following parts are listed as comparable options for similar industrial real-time MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F572MDNGBD#20 | Same RX72M core, identical peripherals, but 2 MB code flash (vs. 4 MB) and 512 KB SRAM (vs. 1 MB); same LFBGA-176 package. | Suitable for cost-sensitive motion controllers where firmware size <2 MB and buffer requirements fit 512 KB SRAM. | Select when full 4 MB flash and 1 MB SRAM are not required - reduces BOM cost without sacrificing EtherCAT or IEEE 1588 capability. |
| R5F572MNHGBD#20 | Same 4 MB flash/1 MB SRAM, but in 144-pin LFQFP (PLQP0144KA-B); lacks Ethernet PHY interface pins and has reduced I/O count (111 vs. 136). | Targeted at space-constrained HMI or gateway designs needing EtherCAT but not dual Ethernet PHY or maximum GPIO count. | Choose for PCB area-limited designs where Ethernet MAC is used via external PHY and fewer GPIOs suffice - avoids BGA assembly complexity. |
Compared with R5F572MDDGBD#20, the R5F572MDNGBD#20 trades flash/SRAM capacity for lower cost in identical packaging, while the R5F572MNHGBD#20 sacrifices I/O count and Ethernet PHY support for QFP manufacturability - both retain full EtherCAT slave and IEEE 1588 functionality but constrain memory or interface scalability.

FAQ
What is the maximum operating frequency and CoreMark score of the R5F572MDDGBD#20?
The R5F572MDDGBD#20 operates at a maximum frequency of 240 MHz and achieves 1396 CoreMark points under benchmark conditions. This performance stems from the RXv3 CPU core's superscalar architecture, dual-issue capability, and optimized instruction pipeline - verified in Renesas' official R01DS0332EJ0120 datasheet Rev.1.20. The R5F572MDDGBD#20 sustains this speed across its full temperature range (–40°C to +105°C) with appropriate power supply decoupling.
Does the R5F572MDDGBD#20 include hardware support for EtherCAT slave functionality?
Yes, the R5F572MDDGBD#20 integrates a certified Beckhoff EtherCAT Slave Controller (ESC) IP core with two physical ports, supporting distributed clocks, process data objects (PDOs), and mailbox communication. It meets EtherCAT conformance requirements for jitter (<1 µs), cycle times down to 100 µs, and hot-connect capability - all implemented in dedicated hardware to offload the RXv3 CPU. This ESC is distinct from generic Ethernet MAC functionality and is explicitly documented for R5F572MDDGBD#20 in the RX72M Group datasheet.
What package type and pin count does the R5F572MDDGBD#20 use?
The R5F572MDDGBD#20 uses the PLQP0176KB-C package: a 176-ball Low-Profile Fine-Pitch Ball Grid Array measuring 24 mm × 24 mm with 0.5 mm pitch. It provides 136 general-purpose I/O pins (including 19× 5-V tolerant), plus dedicated power, clock, reset, and debug signals. This package is confirmed in Table 1.2 of the R01DS0332EJ0120 datasheet and matches the "D" suffix in the part number denoting the industrial temperature grade.
How much on-chip flash and SRAM does the R5F572MDDGBD#20 provide?
The R5F572MDDGBD#20 includes 4 MB of dual-bank code flash memory and 1 MB of on-chip SRAM - split into 512 KB high-speed SRAM (no wait states up to 240 MHz) and 512 KB expansion SRAM (no wait states ≤120 MHz). It also integrates 32 KB of ECC-protected RAM and 8 KB of battery-backed standby RAM. These memory capacities are fixed for the R5F572MDDGBD#20 variant and are specified in Section 1.1 of the official datasheet.
Is IEEE 1588 Precision Time Protocol supported in hardware on the R5F572MDDGBD#20?
Yes, the R5F572MDDGBD#20 includes a dedicated EPTPC (Precision Time Protocol) module tightly coupled to its dual-channel Ethernet MAC (ETHERC). This hardware block performs frame timestamping with sub-100 ns resolution, supports PTP delay request-response mechanisms, and synchronizes local clocks to grandmaster time - all without CPU involvement. The EPTPC is explicitly enabled and characterized for R5F572MDDGBD#20 in the RX72M Group datasheet's peripheral overview and timing specifications.
