Product details
Overview
R5F571MFCDLJ#20 from Renesas is a 32-bit RXv2 microcontroller targeting industrial Ethernet and real-time control applications, featuring a 240 MHz CPU core delivering 480 DMIPS, on-chip single-precision IEEE-754 FPU, 4 MB code flash, 512 KB SRAM (including 32 KB ECC RAM), and integrated IEEE 1588-compliant dual Ethernet MAC with RMII/MII support.
For engineers reviewing the R5F571MFCDLJ#20 datasheet, R5F571MFCDLJ#20 pinout, R5F571MFCDLJ#20 application, or R5F571MFCDLJ#20 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), dual-channel Ethernet + USB 2.0 HS + CAN triple interface concurrency, IEC60730 safety features, and 240 MHz real-time deterministic execution for motion control and protocol gateway designs.
Technical Context
The R5F571MFCDLJ#20 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) - enabling deterministic interrupt latency and secure partitioning in safety-critical firmware. Its clock system supports independent domain scaling: ICLK up to 240 MHz for CPU/SRAM, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers/ADC/SCI.
Real-time data movement is handled by three dedicated DMA subsystems: 8-channel DMAC, 2-channel EXDMAC, and 3-channel EDMAC (for Ethernet), all supporting descriptor-based transfers and event linking via ELC to eliminate CPU polling. The dual Ethernet controller includes full IEEE 1588 PTP hardware timestamping, cut-through forwarding between channels, and Magic Packet/WOL support.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MLDFB#30 | Same RX71M family, 177-pin TFLGA package (PTLG0177KA-A), identical 240 MHz CPU, 4 MB flash, dual Ethernet, but adds high-speed USB 2.0 PHY - no external transceiver needed. | Preferred where board space is constrained (8 × 8 mm vs. 24 × 24 mm) and USB HS PHY integration simplifies layout. | Select R5F571MLDFB#30 when footprint reduction and integrated USB PHY outweigh LFBGA assembly familiarity. |
| R5F572MFCDLJ#20 | Successor RX72M variant with same 176-pin LFBGA, higher 240 MHz CPU, added 2D graphics accelerator, enhanced security (TRNG, secure boot), but reduced data flash (32 KB vs. 64 KB). | Better suited for HMI-rich applications requiring GUI rendering; less optimal for long-term data logging due to smaller data flash endurance budget. | Choose R5F572MFCDLJ#20 only if 2D graphics or advanced security features are mandatory - otherwise R5F571MFCDLJ#20 offers superior cost/performance for pure control+connectivity roles. |
Compared with R5F571MLDFB#30, the R5F571MFCDLJ#20 provides larger PCB footprint tolerance and mature LFBGA assembly yield, while versus R5F572MFCDLJ#20 it retains higher data flash endurance and avoids unnecessary graphics overhead - making it the optimal choice for industrial gateways and PLCs prioritizing reliability, longevity, and deterministic real-time performance.
