Overview
R5F571MFCDFC#V0 from Renesas is a 32-bit RXv2 microcontroller targeting industrial Ethernet and real-time control applications. It operates at up to 240 MHz (480 DMIPS), integrates 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, CAN v2.0B (3 channels), and dual 12-bit A/D converters (29 total channels).
For engineers reviewing the R5F571MFCDFC#V0 datasheet, R5F571MFCDFC#V0 pinout, R5F571MFCDFC#V0 application, or R5F571MFCDFC#V0 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet + PTP timing capability, 240-MHz deterministic real-time performance, and IEC 60730 safety support for Class B compliance.
Technical Context
The R5F571MFCDFC#V0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU - enabling deterministic floating-point execution in motor control and signal processing. 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, serial interfaces).
Real-time responsiveness is enhanced by 298 interrupt sources, ELC (Event Link Controller) for hardware-triggered peripheral coordination, and three DMA controllers (DMACAa: 8 ch, EXDMACa: 2 ch, EDMACa: 3 ch for Ethernet). The device includes dedicated safety features: oscillation-stop detection, CRC calculation unit, IWDTa with window function, and register write protection for critical configuration registers.
