For engineers reviewing the R5F571MLGGFB#V0 datasheet, R5F571MLGGFB#V0 pinout, R5F571MLGGFB#V0 application, or R5F571MLGGFB#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA), validated peripheral configurations for dual Ethernet + USB HS + CAN, and confirmed alternative options meeting IEC 60730 Class B requirements in extended temperature range (–40°C to +105°C).
Technical Context
The R5F571MLGGFB#V0 implements the RXv2 CPU core with single-precision IEEE-754 FPU, dual multiply-accumulate units, and memory protection unit (MPU) - enabling deterministic real-time execution in safety-critical firmware.

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 |
|---|---|---|---|
| R5F571MLHDFB#V0 | Same RX71M group, identical 240 MHz RXv2 core and peripheral set, but in PLQP0144KA-A (144-pin LFBGA, 20 × 20 mm). | Reduced I/O count (111 vs. 127 pins); no PDC or second Ethernet MAC - suitable for space-constrained non-camera, single-Ethernet applications. | Select when board area is constrained and dual Ethernet or CMOS camera interface is unnecessary. |
| R5F572MLHDFB#V0 | RX72M group successor: higher 300 MHz CPU, enhanced EtherCAT slave support, same 144-pin package, but lacks USB HS and second Ethernet MAC. | Optimized for motion control with EtherCAT; no USB battery charging or IEEE 1588 PTP - targets servo drives rather than protocol gateways. | Choose for EtherCAT-based automation where USB/Ethernet coexistence is not required. |
Compared with R5F571MLGGFB#V0, R5F571MLHDFB#V0 offers identical functionality in smaller footprint but fewer I/O and peripherals, while R5F572MLHDFB#V0 shifts focus to motion control with EtherCAT at expense of USB HS and dual Ethernet - making R5F571MLGGFB#V0 uniquely balanced for multi-protocol edge gateways.
