Product details
Overview
R5F571MGHDLJ#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, and dual 12-bit A/D converters - deployed in industrial gateways requiring real-time protocol handling, secure firmware updates, and deterministic network timing.
For engineers reviewing the R5F571MGHDLJ#20 datasheet, R5F571MGHDLJ#20 pinout, R5F571MGHDLJ#20 application, or R5F571MGHDLJ#20 equivalent, this MCU delivers verified support for IEC 60730 safety compliance, hardware-accelerated AES/SHA encryption, and precise time synchronization via PTP - critical for functional safety certification and edge-node time-critical control.
Technical Context
The R5F571MGHDLJ#20 implements the RXv2 CPU core with single-precision IEEE-754 FPU, dual multiply-accumulate units, and memory protection unit (MPU) - enabling deterministic real-time execution and secure memory partitioning. Its clock architecture supports independent domain scaling: ICLK up to 240 MHz, PCLKA up to 120 MHz (for Ethernet, USB, AES), and PCLKB up to 60 MHz (for timers, ADC, serial interfaces).
It integrates dual Ethernet controllers with dedicated EPTPC (IEEE 1588 PTP) and EDMAC (3-channel DMA), plus USBAa (high-speed USB 2.0 with battery charging) and USBb (full-speed host/function), all physically present only in 176-/177-pin packages - confirming R5F571MGHDLJ#20's 176-pin LFBGA package (PLQP0176KB-A) enables full peripheral concurrency without resource contention.
