Product details
Overview
R5F571MGCGFP#V0 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 automation controllers requiring deterministic real-time I/O, secure firmware updates, and networked time synchronization.
For engineers reviewing the R5F571MGCGFP#V0 datasheet, R5F571MGCGFP#V0 pinout, R5F571MGCGFP#V0 application, or R5F571MGCGFP#V0 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), -40°C to +105°C operating range (G-version), integrated FPU for motion control math, hardware AES/SHA encryption, and dual Ethernet with PTP timestamping - all critical for IEC 61131-3 PLCs and EtherCAT slave designs.
Technical Context
The R5F571MGCGFP#V0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. Its clock system supports independent domain scaling: ICLK up to 240 MHz for CPU execution, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers/peripherals - enabling precise timing isolation across real-time and communication subsystems.
It integrates dual Ethernet MACs with dedicated EDMAC (3-channel) and EPTPC (IEEE 1588 PTP) blocks, allowing hardware-accelerated timestamp insertion/extraction and cut-through frame forwarding between channels. The MCU also embeds a full-featured CAN controller (3 modules, 32 mailboxes each), RSPIa (2 channels), QSPI (1 channel), and SDHI supporting 4-bit SD bus - forming a complete industrial connectivity stack without external glue logic.
