Overview
R5F571MGCDLC#20 from Renesas is a 32-bit RXv2 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 IEEE 1588-compliant dual Ethernet MAC - designed for industrial real-time control, networked gateway, and secure edge node applications.
For engineers reviewing the R5F571MGCDLC#20 datasheet, R5F571MGCDLC#20 pinout, R5F571MGCDLC#20 application, or R5F571MGCDLC#20 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), dual-channel high-speed USB 2.0 with battery charging support, 3-channel CAN, 9-channel SCI with LIN/UART/SPI/I²C emulation, and hardware AES/SHA encryption - all validated for IEC 60730 Class B compliance.
Technical Context
The R5F571MGCDLC#20 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet MACs with IEEE 1588 PTP timing engine (EPTPCa), 3-channel CAN supporting ISO 11898-1, and a dedicated EXDMAC controller with cluster transfer mode for deterministic data movement.
Its clock system combines external crystal (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/ADC), and ADCLK up to 60 MHz - enabling precise peripheral timing isolation critical for real-time networking and motor control.
