Overview
R5F571MGHGFC#V0 from Renesas is a 240-MHz 32-bit RXv2 microcontroller with single-precision FPU, 480 DMIPS performance, 4-MB on-chip code flash, 512-KB SRAM (including 32-KB ECCRAM), IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, and CAN v2.0B support - deployed in industrial gateways requiring deterministic real-time control, secure connectivity, and multi-protocol edge processing.
For engineers reviewing the R5F571MGHGFC#V0 datasheet, R5F571MGHGFC#V0 pinout, R5F571MGHGFC#V0 application, or R5F571MGHGFC#V0 equivalent, this page delivers verified technical context, package-specific pin mapping, functional alternatives, and supply-chain readiness for production-grade embedded design.
Technical Context
The R5F571MGHGFC#V0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet controllers (ETHERC) with IEEE 1588 PTP timing accuracy, EPTPC hardware timestamping, and EDMAC DMA channels optimized for low-CPU-load frame handling.
Its clock system combines external crystal oscillation (8–24 MHz), internal HOCO/LOCO sources, and PLL multiplication to deliver independent clocks: ICLK up to 240 MHz, PCLKA up to 120 MHz (for Ethernet, USB, AES), and PCLKB up to 60 MHz (for timers, ADC, serial interfaces). The device supports IEC 60730 safety compliance via oscillation-stop detection, CRC engines, IWDTa windowed watchdog, and A/D self-diagnostic functions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MLHDFC#V0 | Same RX71M family, identical 176-pin LFBGA package, but 2.5-MB code flash and 384-KB SRAM - lower memory capacity, same peripherals and clock specs. | Suitable for cost-optimized gateways where full 4-MB flash is unused; retains dual Ethernet, USB HS, and CAN. | Select when firmware size < 2.5 MB and BOM cost reduction is prioritized over future scalability. |
| R5F566TEHDFP#30 | RX66T family, 160-MHz RXv3 core, 1-MB flash, 192-KB RAM, single Ethernet, no IEEE 1588 - lacks PTP hardware, lower DMIPS (320), smaller memory. | Targeted at motor control with built-in FOC acceleration; insufficient for dual-Ethernet time-critical routing. | Choose only for standalone servo drives or inverters where Ethernet is secondary and real-time motor control dominates. |
Compared with R5F571MGHGFC#V0, the R5F571MLHDFC#V0 offers identical pinout and peripheral set at reduced memory density, while the R5F566TEHDFP#30 trades dual IEEE 1588 Ethernet and memory headroom for motor-control-optimized instruction set and lower cost - making it unsuitable as a drop-in replacement in time-synchronized gateway roles.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F571MGHGFC#V0?
The R5F571MGHGFC#V0 operates at a maximum frequency of 240 MHz and delivers 480 DMIPS performance using the RXv2 CPU core. This benchmark reflects actual integer throughput measured under standard conditions, enabling complex real-time control algorithms and protocol stacks without external co-processors. The R5F571MGHGFC#V0 achieves this with zero wait-state access to code flash at ≤120 MHz and optimized pipeline efficiency.
Does the R5F571MGHGFC#V0 support IEEE 1588 Precision Time Protocol hardware timestamping?
Yes, the R5F571MGHGFC#V0 integrates a dedicated EPTPC (Ethernet PTP Controller) block compliant with IEEE 1588-2008, providing hardware timestamping for Ethernet frames with sub-microsecond accuracy. This capability is tightly coupled with its dual ETHERC modules and requires no CPU overhead - making the R5F571MGHGFC#V0 suitable for time-sensitive networking in industrial automation and power distribution systems.
What package type and pin count does the R5F571MGHGFC#V0 use?
The R5F571MGHGFC#V0 uses the PLQP0176KB-A package: a 176-pin LFBGA with 24 × 24 mm body size and 0.5-mm pitch. It is rated for the G-grade temperature range (–40°C to +105°C) and supports 127 general-purpose I/O pins with 5-V tolerance on 19 pins, open-drain outputs, and configurable pull-up resistors - matching industrial PCB layout and thermal requirements.
How many Ethernet MAC interfaces does the R5F571MGHGFC#V0 include, and what standards do they support?
The R5F571MGHGFC#V0 includes two fully independent Ethernet MAC controllers (ETHERC), each supporting IEEE 802.3 10/100 Mbps operation in full- and half-duplex modes, MII and RMII physical interfaces, and IEEE 802.3x flow control. Both MACs connect to the EPTPC for IEEE 1588 timestamping - a feature confirmed in the R01DS0249EJ0120 datasheet and exclusive to 176-/177-pin RX71M variants like the R5F571MGHGFC#V0.
Is high-speed USB 2.0 with battery charging supported on the R5F571MGHGFC#V0?
Yes, the R5F571MGHGFC#V0 integrates a dedicated USBAa module supporting USB 2.0 high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) operation in host/function/OTG modes, including battery charging detection (BC 1.2). This functionality is physically implemented on pins USBA_VBUS, USBA_DP, USBA_DM, and USBA_ID - and is explicitly enabled only on 176-/177-pin packages such as the R5F571MGHGFC#V0.
