Product details
Overview
R5F571MLCDLJ#20 from Renesas is a 32-bit RXv2 core microcontroller 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 dual 12-bit A/D converters (29 total channels). It targets industrial automation controllers requiring deterministic real-time networking, secure firmware updates, and multi-sensor data acquisition.
For engineers reviewing the R5F571MLCDLJ#20 datasheet, R5F571MLCDLJ#20 pinout, R5F571MLCDLJ#20 application, or R5F571MLCDLJ#20 equivalent, this MCU delivers verified IEEE 1588 time synchronization, hardware AES/SHA encryption, integrated RTC with battery backup, and full peripheral integration for embedded control systems with strict functional safety requirements per IEC 60730.
Technical Context
The R5F571MLCDLJ#20 implements the RXv2 CPU core with single-precision IEEE-754 FPU, dual multiply-accumulate units, and memory protection unit (MPU) for secure execution. Its clock system supports external crystal (8–24 MHz) or internal PLL with independent PCLKA (up to 120 MHz), PCLKB (up to 60 MHz), and ADCLK domains for peripheral timing isolation.
It integrates dual Ethernet MACs with EPTPC (IEEE 1588 PTP), EDMAC (3-channel DMA), and RMII/MII interfaces - all validated for deterministic packet timestamping. The USBAa module provides high-speed USB 2.0 (480 Mbps) with dedicated 8.5 KB buffer and battery charging support, exclusive to 176-/177-pin packages like this one.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MDDFLJ#20 | Same RX71M family, identical 176-pin LFBGA package, but with 2 MB code flash and no USBAa (USB HS) module | Lacks high-speed USB 2.0 and battery charging; suitable for cost-sensitive Ethernet-only gateways without local USB mass storage | Select when USB HS functionality is unnecessary and BOM cost reduction is prioritized over future-proofing |
| R5F572MLHDFB#30 | RX72M family successor; 240 MHz RXv3 core, 4 MB flash, added 2D graphics accelerator, same 176-pin LFBGA, but adds LVDS display interface | Includes integrated display controller for HMI front-ends; higher power consumption due to graphics engine | Choose when human-machine interface with local LCD rendering is required alongside industrial control functions |
Compared with R5F571MLCDLJ#20, R5F571MDDFLJ#20 reduces flash capacity and omits USB HS-lowering cost but limiting local firmware update flexibility-while R5F572MLHDFB#30 adds display acceleration at higher power, making it optimal for HMI-integrated controllers rather than pure networked I/O concentrators.
