Overview
R5F571MFGGFP#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, 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 supports IEC 60730 functional safety compliance.
For engineers reviewing the R5F571MFGGFP#V0 datasheet, R5F571MFGGFP#V0 pinout, R5F571MFGGFP#V0 application, or R5F571MFGGFP#V0 equivalent, key selection criteria include dual Ethernet + PTP timing capability, 240-MHz deterministic real-time performance, on-chip FPU for sensor fusion or motor control math, integrated encryption (AES-128/192/256, SHA-256), and support for deep software standby with 8 KB backup RAM.
Technical Context
The R5F571MFGGFP#V0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It features dual multiply-and-accumulate units, single-cycle 32×32-bit multiplier, and IEEE-754-compliant single-precision FPU - all operating at full 240 MHz system clock speed.
Its peripheral subsystem includes two independent Ethernet controllers (ETHERC) with dedicated PTP timestamping hardware (EPTPC), three CAN modules with 32 mailboxes each, and a flexible clock tree supporting independent domain clocks: ICLK (240 MHz), PCLKA (120 MHz for Ethernet/USB/AES), PCLKB (60 MHz for timers/I/O), and separate ADCLKs (60 MHz) for dual S12AD units.
