Overview
R5F571MLDGFB#V0 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 R5F571MLDGFB#V0 datasheet, R5F571MLDGFB#V0 pinout, R5F571MLDGFB#V0 application, or R5F571MLDGFB#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA), functional pin roles, IEC60730-ready safety features, and validated alternative MCUs for migration paths in industrial automation and networked edge devices.
Technical Context
The R5F571MLDGFB#V0 implements the RXv2 core with 480 DMIPS at 240 MHz, single-precision IEEE-754 FPU, and dual multiply-accumulate units - enabling real-time signal processing in motor control and audio applications. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent PCLK domains (ICLK up to 240 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz) for precise peripheral timing.
It supports full IEC60730 Class B compliance via hardware-assisted self-test: oscillation-stop detection, CRC accelerators, IWDTa with windowing, register write protection, and A/D converter self-diagnostic. The dual Ethernet controller includes EPTPC for IEEE 1588 timestamping and EDMAC with 3-channel DMA - optimized for time-sensitive networking in PLCs and IIoT edge nodes.

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 |
|---|---|---|---|
| R5F571MDDGFB#V0 | Same RX71M family, identical 176-pin LFBGA package, but with 2 MB code flash and no high-speed USB 2.0 PHY. | Suitable for cost-sensitive gateways where dual Ethernet and CAN suffice, but USB host functionality is unnecessary. | Select when BOM cost reduction is prioritized and USB HS is not required; retains same pinout and peripheral set except USBAa module. |
| R5F566TEADFP#30 | RX66T group MCU, 160 MHz, 1 MB flash, single Ethernet MAC, no IEEE 1588, no high-speed USB, 144-pin LQFP package. | Targeted at motor drive inverters with integrated FOC acceleration, not multi-protocol edge gateways. | Choose for motor control-centric designs needing hardware trigonometric functions and lower thermal envelope - not a drop-in replacement. |
Compared with R5F571MLDGFB#V0, R5F571MDDGFB#V0 reduces flash and removes USB HS while retaining pin compatibility and dual Ethernet, whereas R5F566TEADFP#30 trades protocol breadth for motor-specific acceleration and smaller footprint - making it unsuitable for gateway consolidation but optimal for embedded drives.
