Product details
Overview
R5F571MFCDFC#10 from Renesas is a 32-bit RXv2 microcontroller designed for high-performance industrial and networked embedded systems. It operates at up to 240 MHz (480 DMIPS), integrates 4 MB on-chip code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, and dual 12-bit A/D converters - enabling real-time control in smart gateways and programmable logic controllers.
For engineers reviewing the R5F571MFCDFC#10 datasheet, R5F571MFCDFC#10 pinout, R5F571MFCDFC#10 application, or R5F571MFCDFC#10 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet + USB HS support, 240-MHz deterministic real-time execution, and IEC60730 safety features for certified industrial firmware deployment.
Technical Context
The R5F571MFCDFC#10 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU - delivering 480 DMIPS at 240 MHz while supporting memory protection (MPU) and fast interrupt response. Its clock system combines external crystal oscillation, internal PLL, and multiple on-chip oscillators (LOCO/HOCO/IWDT-dedicated), enabling independent domain clocking: ICLK up to 240 MHz, PCLKA up to 120 MHz (for Ethernet/USB/AES), and PCLKB up to 60 MHz (for timers/ADC).
It integrates dual Ethernet MACs with IEEE 1588 PTP hardware timestamping, EPTPC, and 3-channel EDMAC - optimized for time-sensitive networking (TSN) applications. The peripheral set includes three CAN modules (32 mailboxes each), nine SCI interfaces (with LIN/Smart Card modes), four SCIFA with 16-byte FIFOs, two RIIC buses (1 Mbps max), QSPI, SDHI, MMCIF, and parallel data capture - all coordinated via the Event Link Controller (ELC) for CPU-offload operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
