Overview
R5F571MJHDLJ#20 from Renesas is a 32-bit RXv2 microcontroller with 240 MHz CPU, 4 MB on-chip code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, and CAN v2.0B - deployed in industrial gateways requiring deterministic real-time control, secure connectivity, and multi-protocol edge processing.
For engineers reviewing the R5F571MJHDLJ#20 datasheet, R5F571MJHDLJ#20 pinout, R5F571MJHDLJ#20 application, or R5F571MJHDLJ#20 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA), functional pin roles, IEC60730-ready safety features, and validated alternative MCUs for migration or second-sourcing - all grounded in Renesas R01DS0249EJ0120 Rev.1.20.
Technical Context
The R5F571MJHDLJ#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU delivering 480 DMIPS at 240 MHz. It integrates dual Ethernet controllers (ETHERC) with PTP support via EPTPCa and dedicated EDMACa (3-channel DMA), enabling time-synchronized packet timestamping and cut-through forwarding between channels.
Its peripheral set includes USBAa (high-speed USB 2.0 host/function with battery charging), three CAN modules (32 mailboxes each), two SDHI/MMCIF interfaces, and dual S12ADC units (8 + 21 channels) with self-diagnostic and analog disconnection detection - all coordinated by the Event Link Controller (ELC) for hardware-triggered, CPU-free operation across timers, ADCs, and communication peripherals.

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 |
|---|---|---|---|
| R5F571MLHDFB#30 | Same RX71M family, 144-pin LQFP, 2.5 MB flash, 384 KB SRAM, single Ethernet MAC, no USBAa - lacks high-speed USB and second Ethernet channel. | Suitable for cost-sensitive PLC I/O modules where dual Ethernet or battery charging is unnecessary. | Select when board space permits larger LQFP and dual Ethernet is not required; pinout incompatible with R5F571MJHDLJ#20. |
| R5F566TEHDFB#30 | RX66T family, 160 MHz, 1 MB flash, 192 KB SRAM, single Ethernet, no PTP hardware, no USBAa - optimized for motor control with enhanced GPT and encoder interfaces. | Better suited for servo drive applications requiring high-resolution position feedback and fast PWM, but lacks time-sync networking. | Choose for motor-centric designs needing lower BOM cost and simpler timing architecture; not a drop-in replacement due to different peripheral mapping and clock tree. |
