Product details
Overview
R5F571MLCGFC#V0 from Renesas is a 32-bit RXv2 microcontroller with 240 MHz CPU, integrated IEEE 1588-compliant Ethernet MAC, high-speed USB 2.0 (480 Mbps), dual CAN modules, and 4 MB on-chip flash memory. It delivers 480 DMIPS, includes single-precision FPU, 512 KB SRAM (with 32 KB ECC RAM), and supports industrial temperature range (–40°C to +105°C) in a 176-pin LFBGA package. Used in real-time industrial gateways requiring deterministic networking and secure firmware execution.
For engineers reviewing the R5F571MLCGFC#V0 datasheet, R5F571MLCGFC#V0 pinout, R5F571MLCGFC#V0 application, or R5F571MLCGFC#V0 equivalent, key selection criteria include IEEE 1588 PTP timing accuracy, dual-CAN mailbox count (32 per channel), Ethernet DMA channel allocation (3-channel EDMAC), and support for background data flash programming (100,000 write/erase cycles).
Technical Context
The R5F571MLCGFC#V0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual independent Ethernet MACs with dedicated PTP controller (EPTPCa) and 3-channel EDMAC supporting descriptor-based zero-copy transfers - critical for time-sensitive industrial protocol stacks.
Its clock system combines external crystal (8–24 MHz), internal HOCO (16/18/20 MHz), and PLL to generate ICLK up to 240 MHz while independently configuring PCLKA (up to 120 MHz for Ethernet/USB/AES) and PCLKB (up to 60 MHz for timers/ADC). The device uses separate power domains for RTC backup (VBATT), enabling calendar operation during deep software standby.
