Product details
Overview
R5F571MFDDLC#20 from Renesas is a 32-bit RXv2 microcontroller operating at up to 240 MHz, delivering 480 DMIPS with integrated single-precision IEEE-754 FPU, 4 MB on-chip code flash, 512 KB SRAM (including 32 KB ECC RAM), and dual 12-bit A/D converters (8 + 21 channels). It serves as a high-integration control and connectivity hub in industrial Ethernet gateways requiring real-time deterministic processing, IEEE 1588 time synchronization, and secure firmware updates.
For engineers reviewing the R5F571MFDDLC#20 datasheet, R5F571MFDDLC#20 pinout, R5F571MFDDLC#20 application, or R5F571MFDDLC#20 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet MAC with PTP support, high-speed USB 2.0 host/function capability, CAN v2.0B compliance, and IEC60730 safety features for Class B certification.
Technical Context
The R5F571MFDDLC#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual independent DMA controllers (DMACAa: 8 channels; EXDMACa: 2 channels) and a dedicated Ethernet DMA (EDMACa: 3 channels) to offload frame handling from the CPU during concurrent 10/100 Mbps Ethernet traffic and USB 2.0 HS transfers.
Its clock system supports multiple domain-specific clocks: ICLK up to 240 MHz for CPU execution, PCLKA up to 120 MHz for Ethernet/USB/AES peripherals, and PCLKB up to 60 MHz for timers, ADCs, and serial interfaces. The device includes three independent watchdogs - WDTA, IWDTa (with window function), and RTC-dedicated reset - meeting IEC60730 functional safety requirements for self-test and fault recovery.
