Product details
Overview
R5F571MGCDFB#30 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 240 MHz (480 DMIPS), featuring 4 MB on-chip code flash, 512 KB SRAM (including 32 KB ECC RAM), IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, and dual CAN modules - deployed in industrial gateways requiring real-time protocol bridging, secure firmware updates, and deterministic network timing.
For engineers reviewing the R5F571MGCDFB#30 datasheet, R5F571MGCDFB#30 pinout, R5F571MGCDFB#30 application, or R5F571MGCDFB#30 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), 240-MHz CPU with FPU, dual Ethernet + IEEE 1588 PTP support, integrated AES/SHA crypto engines, and IEC60730 safety features for functional safety-critical firmware execution.
Technical Context
The R5F571MGCDFB#30 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, single-cycle 32×32 multiplier, and IEEE-754-compliant single-precision FPU - enabling deterministic floating-point control loops in motor drives and power converters. Its clock system supports independent domain scaling: ICLK up to 240 MHz, PCLKA up to 120 MHz (for Ethernet, USB, AES), and PCLKB up to 60 MHz (for timers, ADC, UART).
It integrates dual Ethernet controllers (ETHERC) with dedicated EPTPC hardware for IEEE 1588 timestamping and EDMAC DMA channels, plus USBAa (high-speed USB 2.0 host/function with battery charging) and USBb (full-speed) - all coexisting on a single die without external PHYs. Safety-critical operation is supported via IWDTa with windowed refresh, CRC units, A/D self-diagnostic, and register write protection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MLDFB#30 | Same RX71M family, identical 176-pin LFBGA package, but 2.5 MB code flash (vs. 4 MB) and no USBAa high-speed USB | Lacks IEEE 1588 PTP hardware and high-speed USB - suitable for cost-sensitive gateways without time-sync or field-upgrade requirements | Select when application does not require dual Ethernet timestamping or 480 Mbps USB connectivity; retains same pinout and peripheral set otherwise |
| R5F572MNDFA#30 | RX72M successor: 240 MHz RXv3 core, 4 MB flash, added 2D graphics accelerator, enhanced security (TRNG, secure boot), but no USBAa or dual Ethernet | Single Ethernet + USB FS only; optimized for HMI-rich devices rather than protocol gateway functions | Choose for next-gen HMI controllers needing GUI acceleration and stronger root-of-trust - not a drop-in replacement due to different peripheral mapping and package (145-pin TFLGA) |
Compared with R5F571MGCDFB#30, R5F571MLDFB#30 offers reduced memory and connectivity at lower cost for simpler gateways, while R5F572MNDFA#30 shifts focus toward graphical user interfaces and security at the expense of IEEE 1588 and high-speed USB - making R5F571MGCDFB#30 uniquely suited for time-critical industrial networking.
