Overview
R5F571MFGDFB#V0 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 240 MHz, delivering 480 DMIPS with integrated single-precision IEEE-754 FPU, 4 MB on-chip code flash, 512 KB SRAM (including 32 KB ECC RAM), and IEEE 1588-compliant dual Ethernet MAC - deployed in industrial gateways requiring deterministic real-time networking, secure firmware updates, and multi-protocol fieldbus coexistence.
For engineers reviewing the R5F571MFGDFB#V0 datasheet, R5F571MFGDFB#V0 pinout, R5F571MFGDFB#V0 application, or R5F571MFGDFB#V0 equivalent, this page delivers verified package mapping (176-pin LFBGA, PLQP0176KB-A), confirmed peripheral channel counts (3 CAN modules, 2 USB interfaces including HS+BC, 9 SCI variants), real-time clock with battery backup, and IEC60730 safety features including CRC, oscillation-stop detection, and A/D self-diagnosis.
Technical Context
The R5F571MFGDFB#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 IEEE 1588 PTP hardware timestamping (EPTPCa) and dedicated EDMACa DMA channels - supporting precise time-synchronized packet handling without CPU intervention.
Its clock system combines external crystal support (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL-based frequency synthesis, allowing independent domain clocks: ICLK up to 240 MHz for CPU, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers/peripherals - enabling mixed-criticality scheduling across real-time and communication subsystems.
