Overview
R5F571MGDDLK#20 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 (including 32 KB ECC RAM), and dual 12-bit A/D converters (8 + 21 channels). It serves as a high-integration industrial control MCU in networked edge devices requiring real-time Ethernet, USB HS, CAN, and secure boot.
For engineers reviewing the R5F571MGDDLK#20 datasheet, R5F571MGDDLK#20 pinout, R5F571MGDDLK#20 application, or R5F571MGDDLK#20 equivalent, this part supports IEEE 1588-compliant Ethernet MAC, high-speed USB 2.0 with battery charging, dual CAN interfaces, and IEC60730 safety features - critical for motion control, PLC modules, and smart grid gateways where deterministic timing, functional safety, and multi-protocol connectivity are mandatory.
Technical Context
The R5F571MGDDLK#20 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates a memory protection unit (MPU), JTAG/FINE debugging, and four low-power modes including deep software standby with 8 KB backup RAM.
Its clock system combines external crystal support (8–24 MHz), internal HOCO (16/18/20 MHz), LOCO (240 kHz), and PLL-based frequency synthesis - enabling independent clock domains: 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. The device uses PLQP0176KB-A package (176-pin LFBGA, 24 × 24 mm, 0.5-mm pitch) with 127 general-purpose I/O pins, 19 of which are 5-V tolerant.
