Product details
Overview
R5F571MJDDBG#20 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 IEEE 1588-compliant dual Ethernet MAC - designed for industrial real-time control, networked gateway, and secure edge node applications requiring deterministic timing and protocol offload.
For engineers reviewing the R5F571MJDDBG#20 datasheet, R5F571MJDDBG#20 pinout, R5F571MJDDBG#20 application, or R5F571MJDDBG#20 equivalent, this MCU supports high-speed USB 2.0 HS with battery charging, CAN FD-capable ISO 11898-1 interfaces (3 channels), quad SPI, SD host interface, and hardware-accelerated AES/SHA encryption - critical for functional safety (IEC 60730) and time-sensitive networking deployments.
Technical Context
The R5F571MJDDBG#20 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet controllers (ETHERC) with dedicated PTP hardware (EPTPCa) compliant with IEEE 1588-2008, supporting precise timestamping and synchronization in industrial automation networks.
Its memory subsystem includes 4 MB code flash with background programming, 64 KB data flash rated for 100,000 erase/write cycles, and segmented SRAM with configurable wait states - 256 KB accessible at full 240 MHz ICLK, while higher-address regions require one wait state above 120 MHz. Clock domains are fully decoupled: ICLK (240 MHz), PCLKA (120 MHz for Ethernet/USB/AES), PCLKB (60 MHz for timers/peripherals), and dedicated ADCLKs (60 MHz).

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 |
|---|---|---|---|
| R5F571MLDDFK#30 | Same RX71M family, LQFP-176 package (PLQP0176KB-A footprint), identical peripherals and memory, but 3.3 V only I/O tolerance | Preferred where PCB rework for BGA assembly is impractical; same thermal profile but lower I/O voltage margin | Select when surface-mount process constraints favor QFP over BGA; verify 5-V signal compatibility in existing designs |
| R5F566TEADFP#30 | RX66T group, 160 MHz max, 2 MB flash, no IEEE 1588 hardware, single Ethernet MAC, no USB HS, 128-pin LQFP | Suitable for cost-sensitive motor control where dual Ethernet and high-speed USB are unnecessary | Choose for simpler motion control applications without time-sensitive networking; lower BOM cost and smaller footprint |
Compared with R5F571MJDDBG#20, the R5F571MLDDFK#30 offers identical functionality in a rework-friendly LQFP package but sacrifices 5-V I/O tolerance, while the R5F566TEADFP#30 reduces complexity and cost by omitting IEEE 1588, dual Ethernet, and USB 2.0 HS - making it viable only where those features are unused.
