Product details
Overview
R5F571MLGGFC#V0 from Renesas is a 32-bit RXv2 microcontroller designed for industrial and networked embedded systems requiring high computational throughput, real-time Ethernet connectivity, and secure firmware execution. It operates at up to 240 MHz (480 DMIPS), integrates 4 MB on-chip code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, and hardware AES/SHA encryption.
For engineers reviewing the R5F571MLGGFC#V0 datasheet, R5F571MLGGFC#V0 pinout, R5F571MLGGFC#V0 application, or R5F571MLGGFC#V0 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), dual-channel Ethernet with PTP support, 240-MHz deterministic real-time performance, and IEC60730 safety features for certified industrial control designs.
Technical Context
The R5F571MLGGFC#V0 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 in safety-critical applications. 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 MACs with dedicated EDMAC (3-channel) and EPTPC (IEEE 1588 PTP) blocks, plus USBAa (high-speed USB 2.0 host/function with battery charging) - all exclusive to 176-/177-pin variants. The device supports full peripheral concurrency via event linking controller (ELC), eliminating CPU intervention for timer-triggered ADC sampling, PWM dead-time generation, or GPIO state changes.
