Product details
Overview
R5F571MLHGFC#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 - deployed in industrial automation controllers requiring deterministic real-time networking and secure firmware updates.
For engineers reviewing the R5F571MLHGFC#V0 datasheet, R5F571MLHGFC#V0 pinout, R5F571MLHGFC#V0 application, or R5F571MLHGFC#V0 equivalent, key selection criteria include IEEE 1588 timestamping accuracy, dual Ethernet channel isolation, 240-MHz real-time interrupt latency, and hardware AES/SHA acceleration for secure boot and OTA updates.
Technical Context
The R5F571MLHGFC#V0 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual independent Ethernet controllers (ETHERC) each with dedicated EDMAC channels and PTP support compliant with IEEE 1588-2008, enabling precise time synchronization in distributed control systems.
Its clock system combines external crystal oscillation (8–24 MHz), internal PLL, and multiple on-chip oscillators (LOCO/HOCO/IWDT-dedicated), allowing independent domain clocking: ICLK up to 240 MHz, PCLKA up to 120 MHz (for ETHERC/AES/USBA), and PCLKB up to 60 MHz (for timers/ADC). The device supports four low-power modes and battery-backed RTC operation via VBATT.
