Product details
Overview
R5F571MLCDFB#V0 from Renesas is a 240-MHz 32-bit RXv2 core MCU with single-precision IEEE-754 FPU, 480 DMIPS performance, 4-MB on-chip code flash, 512-KB SRAM (including 32-KB ECCRAM), and integrated IEEE 1588-compliant Ethernet MAC - deployed in industrial gateways requiring deterministic real-time control, secure firmware updates, and time-synchronized networked I/O.
For engineers reviewing the R5F571MLCDFB#V0 datasheet, R5F571MLCDFB#V0 pinout, R5F571MLCDFB#V0 application, or R5F571MLCDFB#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA, 24 × 24 mm, 0.5-mm pitch), confirmed peripheral channel counts for Ethernet/USB/CAN, and validated alternative MCUs for migration paths in safety-aware embedded systems.
Technical Context
The R5F571MLCDFB#V0 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet MACs (ETHERC) with IEEE 1588 PTP support via EPTPCa and dedicated EDMACa channels - critical for time-sensitive industrial automation.
Its clock system combines external crystal (8–24 MHz) and internal PLL with independent domain 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 - enabling precise peripheral timing isolation without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MLDDFB#V0 | Same RX71M group, identical 176-pin LFBGA package, but with 2.5-MB code flash and reduced peripheral count (single Ethernet MAC, no USBAa). | Suitable for cost-sensitive gateways omitting high-speed USB and second Ethernet port. | Select when BOM cost reduction is prioritized over future-proofing with dual Ethernet and USB HS. |
| R5F566TEADFP#30 | RX66T group, 160-MHz RXv3 core, 1-MB flash, 256-KB RAM, single Ethernet MAC, no IEEE 1588 hardware - lacks PTP timestamping acceleration. | Targeted at servo drive control where motor FOC dominates CPU load, not network time synchronization. | Choose when deterministic motor control latency matters more than sub-microsecond network time alignment. |
Compared with R5F571MLCDFB#V0, R5F571MLDDFB#V0 reduces flash and Ethernet capability for lower cost, while R5F566TEADFP#30 trades PTP hardware and memory size for higher motor-control instruction efficiency - making each viable only where those specific trade-offs align with system-level timing and security requirements.

What package type and pin count does the R5F571MLCDFB#V0 use?
The R5F571MLCDFB#V0 uses the PLQP0176KB-A package: a 176-pin LFBGA with 24 × 24 mm body size, 0.5-mm pitch, and –40°C to +85°C operating temperature range (D-version). This package supports all RX71M peripherals including dual Ethernet MACs, high-speed USB 2.0, and 127 general-purpose I/O pins with 5-V tolerance on 19 pins.
How many Ethernet MAC modules and USB interfaces does the R5F571MLCDFB#V0 integrate?
The R5F571MLCDFB#V0 integrates two IEEE 1588-compliant Ethernet MACs (ETHERC) and two USB interfaces: one high-speed USB 2.0 host/function module with battery charging (USBAa) and one full-speed USB 2.0 host/function module (USBb). Both USB modules include integrated transceivers and on-chip RAM buffers - eliminating external PHY components in most designs.
Is the R5F571MLCDFB#V0 qualified for functional safety standards like IEC 60730?
Yes, the R5F571MLCDFB#V0 includes multiple hardware features required for IEC 60730 Class B compliance: oscillation-stop detection, built-in CRC unit, windowed independent watchdog timer (IWDTa), A/D converter self-diagnostic function, register write protection, and memory protection unit (MPU).
