Overview
R5F571MLGDBG#20 from Renesas is a 32-bit RXv2 microcontroller operating at up to 240 MHz, delivering 480 DMIPS with integrated single-precision IEEE-754 FPU, 4 MB on-chip code flash, 512 KB SRAM (including 32 KB ECC RAM), and IEEE 1588-compliant dual Ethernet MAC - designed for industrial gateway and real-time control applications requiring deterministic timing, secure connectivity, and high peripheral integration.
For engineers reviewing the R5F571MLGDBG#20 datasheet, R5F571MLGDBG#20 pinout, R5F571MLGDBG#20 application, or R5F571MLGDBG#20 equivalent, this MCU supports dual Ethernet with PTP timestamping, high-speed USB 2.0 with battery charging, CAN FD-capable ISO 11898-1 interfaces, quad SPI, SD host interface, and hardware AES/SHA encryption - all within a 176-pin LFBGA package rated for –40°C to +105°C operation.
Technical Context
The R5F571MLGDBG#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual independent clock domains: ICLK up to 240 MHz for CPU execution and PCLKA up to 120 MHz for Ethernet, USB, and crypto peripherals - enabling concurrent high-bandwidth data movement and deterministic real-time processing.
Its peripheral subsystem includes dual Ethernet controllers with dedicated EDMAC (3-channel) and EPTPC (IEEE 1588 PTP) blocks, two USB modules (FS-only USBb + HS+BC USBAa), three CAN channels (32 mailboxes each), and dual 12-bit A/D converters (8 + 21 channels) with self-diagnostic and disconnection detection - all coordinated via the Event Link Controller (ELC) to minimize CPU intervention.

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 |
|---|---|---|---|
| R5F571MLHDFB#30 | Same RX71M family, 144-pin LFQFP package (PLQP0144KA-A), 2.5 MB flash, 384 KB SRAM - smaller footprint, lower I/O count (111 pins), no USBAa or second Ethernet MAC. | Suitable for space-constrained PLC I/O modules where dual Ethernet and high-speed USB are unnecessary. | Select when board area is critical and peripheral count can be reduced; not drop-in compatible due to package and pinout differences. |
| R5F566TEADFP#30 | RX66T group, 160 MHz max, 2 MB flash, 384 KB SRAM, no Ethernet or USB HS, but enhanced MTU3 for motor control (3-phase PWM with encoder input). | Optimized for servo drives and inverters requiring high-resolution PWM and position feedback - lacks networking stack acceleration. | Prefer for motor-centric applications needing >100 ns PWM resolution and encoder interface; trade off networking for motion control precision. |
Compared with R5F571MLGDBG#20, the R5F571MLHDFB#30 reduces package size and peripheral count for cost-sensitive edge nodes, while the R5F566TEADFP#30 trades networking capability for superior motor control timing and PWM fidelity - making the R5F571MLGDBG#20 optimal for converged industrial gateways requiring both real-time control and synchronized connectivity.
