Overview
R5F571MLCDFC#10 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 v2.0B - deployed in industrial gateways requiring deterministic real-time control, secure firmware updates, and multi-protocol connectivity.
For engineers reviewing the R5F571MLCDFC#10 datasheet, R5F571MLCDFC#10 pinout, R5F571MLCDFC#10 application, or R5F571MLCDFC#10 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA), validated peripheral timing constraints, and confirmed alternative MCU options for industrial automation and networked edge devices.
Technical Context
The R5F571MLCDFC#10 implements the RXv2 core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet controllers with IEEE 1588 PTP hardware timestamping, USBAa (high-speed USB 2.0 host/function + BC1.2), and three CAN modules - all synchronized to independent clock domains (ICLK up to 240 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz).
Its memory subsystem includes 4 MB code flash with background programming, 64 KB data flash rated for 100,000 erase/write cycles, 512 KB SRAM (256 KB zero-wait at 240 MHz), and 32 KB ECCRAM with SEC-DED error correction. Real-time operation is reinforced by IWDTa with windowed refresh, RTC with battery backup, and ELC-driven event linking across 119 internal signals.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MLDDFC#10 | Same RX71M core, identical 176-pin LFBGA package, but with 2.5 MB code flash and no USBAa module - lacks high-speed USB 2.0 PHY and battery charging support. | Suitable for cost-sensitive industrial HMI where Ethernet and CAN are primary interfaces, but USB host functionality is unnecessary. | Select when USB 2.0 HS is not required and flash capacity ≤2.5 MB suffices - reduces unit cost by ~18% without sacrificing pin compatibility. |
| R5F566TEADFC#30 | RX66T group MCU, 160 MHz CPU, 1 MB flash, single Ethernet MAC, no IEEE 1588 hardware, 100-pin LQFP package - lower performance, smaller footprint, no USBAa or dual CAN. | Targeted at entry-level servo drives and motor control where deterministic PWM timing dominates over network synchronization. | Choose for simpler motion control applications needing only one Ethernet port and lower BOM cost - requires PCB redesign due to 100-pin LQFP vs. 176-pin LFBGA. |
Compared with R5F571MLCDFC#10, R5F571MLDDFC#10 offers identical packaging and peripheral set minus USBAa and reduced flash, making it a drop-in alternative for non-USB designs; R5F566TEADFC#30 trades dual Ethernet, IEEE 1588, and USB HS for lower cost and smaller size but mandates layout changes and sacrifices time-critical networking capabilities.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F571MLCDFC#10?
The R5F571MLCDFC#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-and-accumulate units. The R5F571MLCDFC#10 sustains this performance with zero-wait-state access to 256 KB of SRAM and optimized flash prefetch via the AFU - critical for real-time control loop execution.
Does the R5F571MLCDFC#10 support IEEE 1588 Precision Time Protocol hardware timestamping?
Yes, the R5F571MLCDFC#10 integrates a dedicated PTP controller (EPTPCa) compliant with IEEE 1588-2008. It captures hardware timestamps on Ethernet frame ingress/egress with sub-microsecond resolution, independent of CPU load. This capability is enabled only on the two Ethernet MAC channels present in the 176-/177-pin RX71M variants - confirming full support in the R5F571MLCDFC#10.
What package type and pin count does the R5F571MLCDFC#10 use?
The R5F571MLCDFC#10 uses the PLQP0176KB-A package: a 176-pin low-profile quad flat BGA with 24 mm × 24 mm body size and 0.5 mm pitch. This matches the pinout and thermal characteristics defined in Renesas' RX71M Group datasheet R01DS0249EJ0120. The package includes an exposed thermal pad for enhanced heat dissipation in industrial applications.
How many Ethernet MAC interfaces does the R5F571MLCDFC#10 include, and what standards do they support?
The R5F571MLCDFC#10 includes two fully independent Ethernet MAC controllers (ETHERC), each supporting IEEE 802.3 10/100 Mbps operation in full- and half-duplex modes, MII/RMII physical layer interfaces, and IEEE 802.3x flow control. Both MACs are linked to the EPTPCa for IEEE 1588 timestamping - a feature confirmed for 176-/177-pin RX71M devices in the official Renesas documentation for R5F571MLCDFC#10.
Is high-speed USB 2.0 with battery charging supported on the R5F571MLCDFC#10?
Yes, the R5F571MLCDFC#10 integrates the USBAa module supporting USB 2.0 high-speed (480 Mbps) host/function operation with Battery Charging Specification 1.2 (BC1.2) compliance. This is explicitly documented for 176- and 177-pin RX71M packages in the R01DS0249EJ0120 datasheet - confirming native support in the R5F571MLCDFC#10 without external transceivers or charge controllers.
