Product details
Overview
R5F571MGGDLJ#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, IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, CAN (3 channels), and dual 12-bit A/D converters - deployed in industrial gateways requiring real-time networking, secure firmware updates, and deterministic I/O control.
For engineers reviewing the R5F571MGGDLJ#20 datasheet, R5F571MGGDLJ#20 pinout, R5F571MGGDLJ#20 application, or R5F571MGGDLJ#20 equivalent, this page delivers verified package mapping (176-pin LFBGA, PLQP0176KB-A), confirmed peripheral channel counts (2× ETHERC, 3× CAN, 9× SCI), clock domain assignments (ICLK ≤240 MHz, PCLKA ≤120 MHz), and functional distinctions versus alternative RX71M variants - all validated against Renesas Document R01DS0249EJ0120 Rev.1.20.
Technical Context
The R5F571MGGDLJ#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU - enabling deterministic floating-point execution at 240 MHz. It integrates dual Ethernet controllers (ETHERC) with IEEE 1588 PTP support via EPTPCa and dedicated EDMACa (3-channel DMA), plus USBAa for high-speed USB 2.0 host/function with battery charging.
Its memory subsystem includes 4 MB code flash (0-wait ≤120 MHz), 64 KB data flash (100k write cycles), 512 KB SRAM (split into 256 KB zero-wait ICLK domains), and 32 KB ECCRAM with SEC-DED - all managed under MPU protection and supported by BGO programming. Clocking uses PLL-synthesized ICLK (240 MHz), independent PCLKA (120 MHz for Ethernet/USB), and PCLKB (60 MHz for timers/A/D).
