Product details
Overview
R5F571MLHDFC#10 from Renesas is a 32-bit RXv2 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 dual 12-bit A/D converters (8 + 21 channels). It serves as a high-integration control and connectivity hub in industrial Ethernet gateways requiring real-time deterministic processing, IEEE 1588 time synchronization, and secure firmware updates.
For engineers reviewing the R5F571MLHDFC#10 datasheet, R5F571MLHDFC#10 pinout, R5F571MLHDFC#10 application, or R5F571MLHDFC#10 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet MAC support with PTP hardware acceleration, high-speed USB 2.0 host/function capability, and IEC60730-compliant safety features including CRC, oscillation-stop detection, and A/D self-diagnostic.
Technical Context
The R5F571MLHDFC#10 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. Its memory subsystem includes 4 MB code flash with adaptive fetch unit (AFU) for zero-wait access up to 120 MHz and one wait state above that frequency, plus 64 KB data flash rated for 100,000 erase/write cycles.
Real-time performance is enhanced by three dedicated DMA controllers - DMAC (8 channels), EXDMAC (2 channels), and EDMAC (3 channels for Ethernet) - alongside the Event Link Controller (ELC) enabling hardware-triggered peripheral coordination without CPU intervention. Clock domain partitioning supports independent operation of ICLK (240 MHz), PCLKA (120 MHz), PCLKB (60 MHz), and dedicated ADCLKs (60 MHz).

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MDDFC#10 | Same RX71M family, identical 176-pin LFBGA package, but with 2 MB code flash (vs. 4 MB) and no high-speed USB 2.0 transceiver | Suitable for cost-sensitive gateways without USB host requirements or firmware update bandwidth constraints | Select when application firmware size < 2 MB and USB is not needed - lower BOM cost without sacrificing pin compatibility or peripheral set |
| R5F572MLHDFC#10 | Successor RX72M variant with same 176-pin LFBGA, 240 MHz CPU, but adds CAN FD support, enhanced security (TRNG, secure boot ROM), and 100 Mbps Ethernet only (no 10 Mbps) | Targeted at next-gen automotive body ECUs and industrial systems requiring CAN FD diagnostics or stronger root-of-trust | Choose for new designs needing CAN FD or certified secure boot; not drop-in due to CAN FD register differences and missing 10 Mbps Ethernet mode |
Compared with R5F571MLHDFC#10, the R5F571MDDFC#10 offers reduced flash and no USB HS but maintains identical timing, peripherals, and safety features - ideal for footprint-constrained legacy upgrades. The R5F572MLHDFC#10 extends functionality with CAN FD and TRNG but sacrifices backward compatibility in Ethernet speed modes and security initialization flow.
