Product details
Overview
R5F571MLHDFP#V0 from Renesas is a 32-bit RXv2 microcontroller with 240 MHz CPU, 480 DMIPS performance, single-precision IEEE-754 FPU, 4 MB on-chip code flash, 512 KB SRAM, and integrated IEEE 1588-compliant Ethernet MAC - designed for industrial automation controllers requiring deterministic real-time communication, secure firmware updates, and high-precision analog sensing.
For engineers reviewing the R5F571MLHDFP#V0 datasheet, R5F571MLHDFP#V0 pinout, R5F571MLHDFP#V0 application, or R5F571MLHDFP#V0 equivalent, this MCU delivers verified 240-MHz operation with hardware-accelerated AES/SHA encryption, dual 12-bit ADCs (29 total channels), CAN FD-ready interfaces, and low-power deep software standby mode supporting battery-backed RTC - critical for edge gateway and motor control designs.
Technical Context
The R5F571MLHDFP#V0 implements the RXv2 core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual DMAC (8-channel + 2-channel EXDMA), DTC, and three independent Ethernet DMA channels (EDMACa) to offload frame processing from the CPU while maintaining IEEE 1588 timestamp accuracy via EPTPCa.
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/ADCs - enabling precise timing isolation between real-time control loops and communication stacks.
