Product details
Overview
R5F571MFCDFP#30 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 240 MHz, delivering 480 DMIPS and featuring single-precision IEEE-754 FPU, 4 MB on-chip code flash, 512 KB SRAM (including 32 KB ECC RAM), and integrated IEEE 1588-compliant Ethernet MAC - deployed in industrial gateways requiring deterministic real-time networking and secure firmware updates.
For engineers reviewing the R5F571MFCDFP#30 datasheet, R5F571MFCDFP#30 pinout, R5F571MFCDFP#30 application, or R5F571MFCDFP#30 equivalent, key selection criteria include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet MAC support, high-speed USB 2.0 with battery charging, CAN v2.0B compliance, and hardware AES/SHA encryption for IEC 60730 Class B certification.
Technical Context
The R5F571MFCDFP#30 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) - enabling deterministic interrupt latency and secure partitioning of firmware and data. It integrates dual Ethernet controllers (ETHERC) with IEEE 1588 PTP timing via EPTPC and dedicated EDMAC channels for zero-copy frame handling.
Its clock system combines external crystal (8–24 MHz), internal HOCO (16/18/20 MHz), and PLL for independent domain scaling: ICLK up to 240 MHz, PCLKA up to 120 MHz (for ETHERC, USBA, AES), and PCLKB up to 60 MHz (for timers, ADC, RTC). Real-time operation is reinforced by four low-power modes, IWDTa with windowed refresh, and RTC with battery backup via VBATT.
