Product details
Overview
R5F571MJDDLK#20 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 gateway and real-time control applications requiring deterministic timing, secure connectivity, and high peripheral integration.
For engineers reviewing the R5F571MJDDLK#20 datasheet, R5F571MJDDLK#20 pinout, R5F571MJDDLK#20 application, or R5F571MJDDLK#20 equivalent, this MCU supports dual Ethernet with PTP timestamping, high-speed USB 2.0 with battery charging, CAN FD-capable ISO 11898-1 interfaces, SD host interface, quad SPI, and hardware AES/SHA encryption - all within a 177-pin TFLGA package rated for –40°C to +105°C operation.
Technical Context
The R5F571MJDDLK#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual independent DMA controllers (DMACa: 8 channels; EXDMACa: 2 channels) and a dedicated Ethernet DMA (EDMACa: 3 channels) to offload frame processing from the CPU while maintaining real-time determinism via event linking (ELC) across 119 internal signals.
Clock domain separation enables concurrent operation: ICLK up to 240 MHz for CPU execution, PCLKA up to 120 MHz for Ethernet/USB/AES peripherals, and PCLKB up to 60 MHz for timers/ADC/SCI. The device includes three independent A/D converters (S12AD unit 0: 8-channel; unit 1: 21-channel), two 12-bit D/A channels, and a temperature sensor - all synchronized to dedicated peripheral clocks (PCLKC/PCLKD) for noise-immune analog acquisition.

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 |
|---|---|---|---|
| R5F571MLDLK#20 | Same RX71M family, identical 177-pin TFLGA package, but with 2 MB code flash (vs. 4 MB) and no SDHI interface | Suitable for cost-sensitive gateways omitting local SD-based logging or firmware storage | Select when flash capacity and SD host functionality are not required; reduces BoM cost by ~12% |
| R5F566TEADFP#30 | RX66T group, 160 MHz max, 1 MB flash, single Ethernet MAC, no IEEE 1588, no USB HS, 144-pin LQFP package | Targeted at motor control with enhanced GPTA PWM resolution, but lacks dual Ethernet and cryptographic acceleration | Choose for servo drive applications prioritizing PWM precision over network security and redundancy |
