Product details
Overview
R5F571MLGDFP#30 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, and IEEE 1588-compliant dual Ethernet MAC - designed for industrial gateway and real-time control applications requiring deterministic timing, secure connectivity, and high peripheral integration.
For engineers reviewing the R5F571MLGDFP#30 datasheet, R5F571MLGDFP#30 pinout, R5F571MLGDFP#30 application, or R5F571MLGDFP#30 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet + USB HS + CAN triple interface concurrency, 240-MHz real-time execution capability, and IEC60730-ready safety features including CRC, IWDTa, and A/D self-diagnostic.
Technical Context
The R5F571MLGDFP#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual independent DMA controllers (DMACa: 8 channels; EXDMACa: 2 channels) and a dedicated Ethernet DMA (EDMACa: 3 channels) to offload frame processing from the CPU while maintaining sub-microsecond interrupt latency.
Its clock system supports simultaneous domain-specific frequencies: 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, ADC, and serial interfaces - enabling precise real-time scheduling without bus contention.
