Product details
Overview
R5F571MLDDFC#10 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, IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, CAN v2.0B (3 channels), and dual 12-bit A/D converters (29 total channels). It targets industrial automation controllers requiring real-time deterministic I/O, secure firmware updates, and time-synchronized networked operation.
For engineers reviewing the R5F571MLDDFC#10 datasheet, R5F571MLDDFC#10 pinout, R5F571MLDDFC#10 application, or R5F571MLDDFC#10 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet + PTP support, 240-MHz real-time performance with FPU, and IEC60730 safety features including CRC, oscillation-stop detection, and A/D self-diagnosis.
Technical Context
The R5F571MLDDFC#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual independent Ethernet controllers (ETHERC) with IEEE 1588 PTP hardware timestamping (EPTPC) and dedicated EDMAC channels - one for each ETHERC channel plus one for EPTPC - enabling low-latency, hardware-accelerated time-sensitive networking.
Its clock system supports multiple independent domains: ICLK up to 240 MHz for CPU execution, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers/peripherals. The device includes three distinct memory spaces - 4 MB code flash with background programming, 512 KB SRAM (256 KB zero-wait at 240 MHz), and 32 KB ECCRAM - all managed by an MPU supporting memory protection for safety-critical tasks.

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 |
|---|---|---|---|
| R5F571MLHDFC#10 | Same RX71M group, identical 176-pin LFBGA package and peripheral set, but with 2.5 MB code flash instead of 4 MB | Suitable where firmware image size is <2 MB and cost optimization is prioritized over future-proofing | Select when BOM cost sensitivity outweighs need for bootloader + application + OTA update partitioning in flash |
| R5F566TKEDFC#30 | RX66T group, 160 MHz max, no IEEE 1588 PTP hardware, single Ethernet MAC, 2 MB flash, 384 KB SRAM | Targeted at servo drive control with enhanced motor control timers (GPTP), not time-synchronized networking | Choose for motor control-centric applications where PTP and dual Ethernet are unnecessary - lower power and cost |
Compared with R5F571MLDDFC#10, the R5F571MLHDFC#10 offers identical real-time performance and safety features but reduced flash capacity for cost-constrained deployments, while the R5F566TKEDFC#30 trades PTP/Ethernet capability for higher motor-control timer precision and lower thermal footprint - making it unsuitable for time-synchronized networking but optimal for servo amplifier designs.
