Overview
R5F571MGCDFC#30 from Renesas is a 32-bit RXv2 microcontroller with 240 MHz CPU, integrated IEEE 1588-compliant Ethernet MAC, high-speed USB 2.0 (480 Mbps), dual CAN interfaces, 4 MB on-chip flash, and 512 KB SRAM - designed for industrial networking, gateway, and real-time control applications requiring deterministic timing and secure connectivity.
For engineers reviewing the R5F571MGCDFC#30 datasheet, R5F571MGCDFC#30 pinout, R5F571MGCDFC#30 application, or R5F571MGCDFC#30 equivalent, this MCU delivers verified 480 DMIPS performance, hardware FPU, ECC-protected RAM, IEC60730 safety features, and dual Ethernet/USB/SDHI peripheral concurrency - critical for time-sensitive embedded systems with functional safety requirements.
Technical Context
The R5F571MGCDFC#30 implements the RXv2 core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual independent DMA controllers (DMACa + EXDMACa), event-link controller (ELC) for hardware-triggered peripheral coordination, and clock domain separation across ICLK (240 MHz), PCLKA (120 MHz), and PCLKB (60 MHz) to isolate real-time, communication, and low-power subsystems.
Its peripheral set includes two IEEE 1588-capable Ethernet MACs with EPTPC timestamping, USBAa supporting high-speed USB 2.0 with battery charging, and S12ADC units offering 0.48 µs 12-bit conversion - all synchronized via configurable clock dividers and validated for IEC60730 Class B compliance through oscillation detection, CRC, IWDTa, and register write protection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MLDFC#30 | Same RX71M family, identical 176-pin LFBGA package and 240 MHz CPU, but with 2 MB flash (vs. 4 MB) and no USBAa high-speed USB module. | Suitable for cost-sensitive gateways omitting high-speed USB host functionality; lacks battery charging support and HS PHY. | Select when USB 2.0 FS only is required and flash budget is ≤2 MB. |
| R5F572MNDFA#30 | RX72M family successor with same pinout, 240 MHz CPU, 4 MB flash, but adds 2D graphics accelerator, enhanced security (TRNG, secure boot), and single-channel Ethernet. | Targets HMI-integrated gateways; replaces dual Ethernet with display engine - not drop-in for legacy dual-Ethernet designs. | Choose for new designs needing GUI support and stronger security; requires validation of single-Ethernet vs. dual-Ethernet topology. |
Compared with R5F571MGCDFC#30, R5F571MLDFC#30 reduces flash and removes high-speed USB - lowering BOM cost where those features are unused; R5F572MNDFA#30 shifts focus to HMI and security at the expense of dual Ethernet, making it unsuitable for existing dual-port network architectures without redesign.
