Product details
Overview
R5F571MLHGFP#V0 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 240 MHz, delivering 480 DMIPS with integrated single-precision IEEE-754 FPU, 4 MB on-chip code flash, 512 KB SRAM (including 32 KB ECC RAM), and IEEE 1588-compliant dual Ethernet MAC - designed for industrial real-time control, networked gateway, and secure edge node applications.
For engineers reviewing the R5F571MLHGFP#V0 datasheet, R5F571MLHGFP#V0 pinout, R5F571MLHGFP#V0 application, or R5F571MLHGFP#V0 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet + high-speed USB 2.0 + CAN triple interface concurrency, 240-MHz deterministic real-time performance, and IEC60730 safety support including CRC, IWDTa, and A/D self-diagnostic functions.
Technical Context
The R5F571MLHGFP#V0 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) - enabling ultra-compact code and deterministic interrupt latency down to 5 CPU cycles. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent peripheral clock domains (ICLK up to 240 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz).
Real-time capability is reinforced by 29 timers including MTU3a (9-channel, complementary PWM with dead-time control), GPTA (4-channel synchronized PWM), and ELC-driven event linking across 119 internal signals - eliminating CPU intervention for time-critical peripheral coordination. Safety compliance is embedded via oscillation-stop detection, register write protection, and hardware-accelerated AES/SHA crypto engines.

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 |
|---|---|---|---|
| R5F571MLHDFP#V0 | Same RX71M core, identical peripherals and memory, but in 176-pin LFQFP (PLQP0176KB-A) instead of LFBGA - larger footprint, no thermal pad, higher trace inductance. | Better suited for prototyping and low-volume manual assembly; less optimal for high-density, thermally constrained industrial PCBs. | Select when board-level rework or hand-soldering is required; avoid for production designs needing thermal reliability or signal integrity at 240 MHz. |
| R5F571MDDFP#V0 | Same package and pinout, but reduced flash (2 MB vs. 4 MB) and SRAM (384 KB vs. 512 KB); lacks SDHI and second Ethernet MAC channel. | Targeted at cost-sensitive gateway nodes where single Ethernet port and smaller firmware image suffice. | Choose for budget-constrained deployments where dual Ethernet and >2.5 MB firmware space are not required - verified pin-compatible drop-in replacement. |
Compared with R5F571MLHGFP#V0, the R5F571MLHDFP#V0 offers identical functionality in a through-hole-friendly package at the expense of thermal performance, while the R5F571MDDFP#V0 provides a lower-cost variant with scaled memory and connectivity - both retain full software compatibility and require no firmware changes.
