Overview
R5F571MGCGFB#V0 from Renesas is a 32-bit RXv2 microcontroller designed for high-performance industrial and networked embedded systems. It operates at up to 240 MHz, delivers 480 DMIPS, integrates 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 - enabling real-time control in motor drives and industrial gateways.
For engineers reviewing the R5F571MGCGFB#V0 datasheet, R5F571MGCGFB#V0 pinout, R5F571MGCGFB#V0 application, or R5F571MGCGFB#V0 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet + USB HS support, 240-MHz deterministic real-time execution, and IEC60730 safety features including CRC, oscillation-stop detection, and A/D self-diagnostic capability.
Technical Context
The R5F571MGCGFB#V0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling ultra-compact code and fast interrupt response. It supports single-precision IEEE-754 floating-point arithmetic and two multiply-accumulate units for signal processing workloads.
Its clock system combines external crystal input (8–24 MHz), internal PLL, and multiple on-chip oscillators (LOCO, HOCO, IWDT-dedicated) to drive independent domain clocks: ICLK up to 240 MHz, PCLKA up to 120 MHz (for Ethernet/USB/AES), and PCLKB up to 60 MHz (for timers/ADC). The device includes an event link controller (ELC) that enables hardware-triggered peripheral coordination without CPU intervention.
