Product details
Overview
R5F571MLHDLK#20 from Renesas is a 32-bit RXv2 core MCU operating at up to 240 MHz (480 DMIPS), featuring 4 MB on-chip code flash, 512 KB SRAM (including 32 KB ECC RAM), IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, CAN v2.0B (3 channels), and 12-bit A/D converters (29 total channels). It targets industrial automation gateways requiring real-time deterministic networking, secure firmware updates, and multi-protocol fieldbus integration.
For engineers reviewing the R5F571MLHDLK#20 datasheet, R5F571MLHDLK#20 pinout, R5F571MLHDLK#20 application, or R5F571MLHDLK#20 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA, 24 × 24 mm, 0.5-mm pitch), functional pinout, IEC60730-ready safety features, and validated alternative MCUs for industrial control and networked edge devices.
Technical Context
The R5F571MLHDLK#20 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates dual Ethernet controllers with IEEE 1588 PTP hardware timestamping, EPTPC, and EDMAC - supporting cut-through frame transfer between channels and hardware-accelerated time synchronization for sub-microsecond precision in motion control networks.
Its clock system combines external crystal oscillators (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL for independent domain scaling: ICLK up to 240 MHz, PCLKA up to 120 MHz (for ETHERC/USBA/AES), PCLKB up to 60 MHz (for timers/SCI), and dedicated ADCLKs for dual S12AD units. Power management includes four low-power modes and VBATT-backed RTC operation.
