Product details
Overview
R5F571MFHDFC#V0 from Renesas is a 32-bit RXv2 microcontroller with 240 MHz CPU, 4 MB on-chip code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, and CAN interface - deployed in industrial gateways requiring deterministic real-time control, secure firmware updates, and multi-protocol connectivity.
For engineers reviewing the R5F571MFHDFC#V0 datasheet, R5F571MFHDFC#V0 pinout, R5F571MFHDFC#V0 application, or R5F571MFHDFC#V0 equivalent, key selection criteria include its 177-pin TFLGA package, dual Ethernet + USB HS + CAN triple-protocol capability, 240-MHz FPU-enabled processing for motion control algorithms, and IEC60730 safety support for Class B compliance.
Technical Context
The R5F571MFHDFC#V0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU delivering 480 DMIPS at 240 MHz. It integrates dual independent Ethernet controllers (ETHERC) each with dedicated EDMAC channels and EPTPC hardware timestamping aligned to IEEE 1588-2008.
Its clock system combines external crystal input (8–24 MHz), internal HOCO/LOCO oscillators, and PLL-based frequency synthesis to drive ICLK up to 240 MHz while assigning PCLKA (≤120 MHz) to Ethernet/USB/AES and PCLKB (≤60 MHz) to timers, ADC, and serial interfaces - enabling precise peripheral timing isolation.
