Product details
Overview
R5F571MLCDFP#10 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 240 MHz, delivering 480 DMIPS with integrated single-precision IEEE-754 FPU, 2 MB on-chip code flash memory, and 512 KB SRAM. It integrates IEEE 1588-compliant Ethernet MAC, CAN (ISO 11898-1), high-speed USB 2.0 with battery charging, and dual 12-bit A/D converters - deployed in industrial gateways requiring deterministic real-time control and networked I/O consolidation.
For engineers reviewing the R5F571MLCDFP#10 datasheet, R5F571MLCDFP#10 pinout, R5F571MLCDFP#10 application, or R5F571MLCDFP#10 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), 240-MHz CPU performance with hardware FPU, dual Ethernet + CAN + USB HS connectivity, and support for IEC 60730 functional safety diagnostics including CRC, oscillation-stop detection, and A/D self-test.
Technical Context
The R5F571MLCDFP#10 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and MPU support. It features dual clock domains: ICLK up to 240 MHz for CPU execution and PCLKA up to 120 MHz for Ethernet, USB, and AES peripherals - enabling concurrent high-bandwidth data movement and deterministic real-time processing.
Its peripheral subsystem includes three independent communication stacks: IEEE 1588 Ethernet MAC with EPTPC timestamping engine, USBAa high-speed USB 2.0 host/function controller with 8.5 KB buffer, and triple CAN modules each supporting 32 mailboxes - all coordinated via Event Link Controller (ELC) for hardware-triggered, CPU-free inter-module synchronization.
