Overview
R5F571MGGDFB#30 from Renesas is a 32-bit RXv2 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 R5F571MGGDFB#30 datasheet, R5F571MGGDFB#30 pinout, R5F571MGGDFB#30 application, or R5F571MGGDFB#30 equivalent, this MCU supports simultaneous high-speed USB 2.0 HS + FS, triple CAN FD-capable channels (ISO 11898-1), SDHI/MMCIF, QSPI, and hardware AES/SHA crypto - critical for IEC 62443-compliant edge controllers and functional-safety-ready motor drives.
Technical Context
The R5F571MGGDFB#30 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet MACs with dedicated EPTPC (IEEE 1588 PTP) and EDMAC (3-channel DMA), supporting precise time synchronization and low-CPU-load frame handling in industrial automation systems.
Its clock system combines external crystal (8–24 MHz), internal HOCO (16/18/20 MHz), and PLL to generate independent 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 without clock domain conflicts.
