Overview
R5F571MLCDFP#30 from Renesas is a 32-bit RXv2 microcontroller with 240 MHz max operating frequency, 4 MB on-chip code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, and high-speed USB 2.0 with battery charging - designed for industrial gateway and real-time edge control applications requiring deterministic timing, secure connectivity, and multi-protocol I/O.
For engineers reviewing the R5F571MLCDFP#30 datasheet, R5F571MLCDFP#30 pinout, R5F571MLCDFP#30 application, or R5F571MLCDFP#30 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), dual-channel Ethernet with PTP support, 240-MHz FPU-enabled real-time processing, and integrated AES/SHA encryption for secure firmware updates and data-in-transit protection.
Technical Context
The R5F571MLCDFP#30 implements the RXv2 CPU core with single-precision IEEE-754 FPU, 480 DMIPS performance at 240 MHz, and hardware-accelerated DSP instructions including two multiply-and-accumulate units. Its memory subsystem includes 4 MB code flash with background programming, 64 KB data flash rated for 100,000 erase/write cycles, and 512 KB SRAM with 32 KB ECCRAM for safety-critical execution.
Peripherals are clocked across four domains: ICLK (up to 240 MHz for CPU), PCLKA (up to 120 MHz for Ethernet/USB/AES), PCLKB (up to 60 MHz for timers/SCI), and PCLKC/PCLKD (60 MHz for dual 12-bit ADC units). It supports IEEE 1588 timestamping via EPTPCa linked to ETHERC, and features event-linking (ELC) for hardware-triggered peripheral coordination without CPU intervention.
