Overview
R5F571MGGDLK#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 R5F571MGGDLK#20 datasheet, R5F571MGGDLK#20 pinout, R5F571MGGDLK#20 application, or R5F571MGGDLK#20 equivalent, this MCU delivers verified 480 DMIPS performance, hardware-accelerated AES/SHA encryption, dual-channel Ethernet with PTP timestamping, and 127 GPIOs with 5-V tolerance - critical for IEC 60730-compliant motor drives and time-sensitive networking (TSN)-ready infrastructure.
Technical Context
The R5F571MGGDLK#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet controllers (ETHERC) with dedicated EPTPC hardware for IEEE 1588-2008 timestamping and EDMAC DMA channels to offload frame handling without CPU intervention.
Its clock system supports independent domain scaling: ICLK up to 240 MHz for CPU execution, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers/peripherals. The device includes two 12-bit A/D converters (8 + 21 channels), 2-channel D/A, RTC with battery backup, and hardware-based security modules including AES-128/192/256, DES/TDES, and SHA-1/224/256.

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 |
|---|---|---|---|
| R5F571MLGDFP#30 | LQFP-144 package (20 × 20 mm), 2.5 MB flash, 384 KB SRAM, single Ethernet MAC, no USB HS - lacks PTP hardware and high-speed USB transceiver. | Suitable for cost-sensitive PLC I/O modules where dual Ethernet and battery charging are unnecessary. | Select when board space permits larger LQFP and dual Ethernet/USB HS are not required. |
| R5F572MLGDFP#30 | RX72M family; same LQFP-144 package but adds 2D graphics accelerator, 32 KB instruction cache, and enhanced CAN FD support - no IEEE 1588 hardware. | Better suited for HMI-enabled edge controllers needing local display rendering and CAN FD diagnostics. | Choose for human-machine interface integration where graphical UI and CAN FD outweigh PTP precision needs. |
Compared with R5F571MGGDLK#20, the R5F571MLGDFP#30 reduces peripheral count and package size at the expense of IEEE 1588 and USB HS capabilities, while the R5F572MLGDFP#30 shifts focus toward graphics and CAN FD - making R5F571MGGDLK#20 uniquely optimal for time-critical industrial networking where hardware timestamping and secure high-bandwidth connectivity are non-negotiable.
