Renesas R5F571MGCDLJ#20

Overview

R5F571MGCDLJ#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 control and networked embedded systems requiring real-time determinism, functional safety support (IEC60730), and secure connectivity.

For engineers reviewing the R5F571MGCDLJ#20 datasheet, R5F571MGCDLJ#20 pinout, R5F571MGCDLJ#20 application, or R5F571MGCDLJ#20 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), 240-MHz timing-critical peripheral clocking (PCLKA up to 120 MHz), dual Ethernet + PTP timestamping capability, and hardware AES/SHA encryption - all validated for operation from –40°C to +85°C.

Technical Context

The R5F571MGCDLJ#20 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU. Its memory subsystem includes 4 MB code flash (0-wait ≤120 MHz), 64 KB data flash (100k write cycles), and 512 KB SRAM segmented into no-wait (256 KB) and wait-state regions based on ICLK frequency.

Peripheral timing is partitioned across five clock domains: ICLK (up to 240 MHz for CPU), PCLKA (up to 120 MHz for ETHERC, USBA, AES), PCLKB (up to 60 MHz for timers, SCI, I²C), PCLKC/PCLKD (60 MHz for S12AD units), and FCLK/BCLK (60 MHz for flash and external bus). The ELC enables hardware-triggered inter-module coordination without CPU intervention.
