Product details
Overview
R5F571MLCGFP#V0 from Renesas is a 32-bit RXv2 microcontroller targeting industrial Ethernet and real-time control applications, featuring a 240-MHz CPU core delivering 480 DMIPS, on-chip single-precision IEEE-754 FPU, 4-MB code flash, 512-KB SRAM (including 32-KB ECCRAM), and integrated IEEE 1588-compliant dual Ethernet MAC with RMII/MII support.
For engineers reviewing the R5F571MLCGFP#V0 datasheet, R5F571MLCGFP#V0 pinout, R5F571MLCGFP#V0 application, or R5F571MLCGFP#V0 equivalent, this MCU is selected for deterministic real-time control in networked industrial equipment where synchronized time-stamping, high-speed USB 2.0 HS with battery charging, CAN FD-capable interfaces, and functional safety features per IEC 60730 are required.
Technical Context
The R5F571MLCGFP#V0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet controllers (ETHERC) with dedicated PTP hardware (EPTPC) compliant with IEEE 1588-2008 for sub-microsecond timestamp accuracy and hardware-assisted cut-through frame forwarding between channels.
Its clock system supports independent domain scaling: ICLK up to 240 MHz for CPU execution, PCLKA up to 120 MHz for Ethernet/USB/AES peripherals, and PCLKB up to 60 MHz for timers, ADCs, and serial interfaces. The device includes three CAN modules (ISO 11898-1 compliant), four SCIFA UARTs with 16-byte FIFOs, and two USB modules - one full-speed (USBb), one high-speed with battery charging (USBAa) - both supporting OTG operation.
