Product details
Overview
R5F571MFCDFP#10 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 240 MHz (480 DMIPS), featuring 4 MB on-chip code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, CAN (3 channels), and dual 12-bit A/D converters (29 total channels). It targets industrial automation gateways requiring real-time deterministic networking, secure firmware updates, and multi-protocol fieldbus interfacing.
For engineers reviewing the R5F571MFCDFP#10 datasheet, R5F571MFCDFP#10 pinout, R5F571MFCDFP#10 application, or R5F571MFCDFP#10 equivalent, key selection criteria include IEEE 1588 PTP timestamping accuracy, dual Ethernet channel isolation, USB 2.0 HS + FS coexistence, 240-MHz real-time interrupt latency, and IEC 60730 safety support including CRC, self-diagnostic ADC, and register write protection.
Technical Context
The R5F571MFCDFP#10 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 controllers (ETHERC) each with dedicated EDMAC channels and EPTPC hardware-accelerated IEEE 1588 timestamping - supporting precise time synchronization in distributed control systems.
Its clock system combines external crystal oscillation (8–24 MHz), internal HOCO/LOCO sources, and PLL multiplication to generate independent clocks: ICLK (up to 240 MHz for CPU), PCLKA (up to 120 MHz for Ethernet/USB/AES), and PCLKB (up to 60 MHz for timers/ADC). The device supports four low-power modes and battery-backed RTC operation via VBATT.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F571MFCDFP#10?
The R5F571MFCDFP#10 operates at a maximum frequency of 240 MHz and delivers 480 DMIPS performance. This is achieved through the RXv2 CPU core's 5-stage pipeline, variable-length instruction set, and dual multiply-accumulate units - enabling deterministic execution of motion control algorithms and protocol stacks in real time. The R5F571MFCDFP#10 sustains this performance with zero-wait-state access to code flash up to 120 MHz and efficient cache-like AFU hit behavior at 240 MHz.
Does the R5F571MFCDFP#10 support IEEE 1588 Precision Time Protocol hardware timestamping?
Yes, the R5F571MFCDFP#10 includes a dedicated EPTPC (Ethernet PTP Controller) block connected to both Ethernet MACs, providing hardware-accelerated IEEE 1588 timestamping with sub-microsecond accuracy. This allows precise time synchronization across distributed nodes without CPU overhead - a critical capability for time-sensitive networking in industrial automation. The R5F571MFCDFP#10 supports both one-step and two-step PTP message handling and integrates with the MTU3/GPT timers for timestamp correlation.
What safety certifications and features does the R5F571MFCDFP#10 provide for IEC 60730 compliance?
The R5F571MFCDFP#10 includes multiple hardware features required for IEC 60730 Class B compliance: oscillation-stoppage detection, built-in CRC calculation unit, self-diagnostic A/D converter, independent watchdog timer (IWDTa) with window function, and register write protection. These capabilities enable safe startup, runtime monitoring, and fault recovery without external components. The R5F571MFCDFP#10 documentation explicitly lists these as "useful functions for IEC60730 compliance," and its safety manual provides guidance for qualifying designs.
How many Ethernet MAC interfaces does the R5F571MFCDFP#10 integrate, and what PHY interfaces are supported?
The R5F571MFCDFP#10 integrates two fully independent IEEE 802.3-compliant Ethernet MACs (ETHERC), each with dedicated EDMAC DMA channels and EPTPC timestamping. Both support MII and RMII physical layer interfaces at 10/100 Mbps full/half-duplex. The R5F571MFCDFP#10 does not include integrated PHYs - external PHY ICs must be used, but the MACs support standard MII/RMII signaling and features like Magic Packet wake-on-LAN and flow control per IEEE 802.3x.
What is the flash and RAM configuration of the R5F571MFCDFP#10, and how is memory protection implemented?
The R5F571MFCDFP#10 features 4 MB of on-chip code flash memory with background programming/erasing (BGO), 512 KB of general-purpose SRAM (with 256 KB zero-wait at 240 MHz), 32 KB of ECC-protected RAM (SEC-DED), and 8 KB of battery-backed standby RAM. Memory protection is enforced via an on-chip MPU (Memory Protection Unit) that defines up to 16 regions with configurable access permissions (read/write/execute) and privilege levels - preventing unauthorized code execution or data corruption in multitask environments. The R5F571MFCDFP#10 also supports Trusted Memory (TM) protection for flash blocks 8 and 9.
