Overview
R5F571MFCDLK#20 from Renesas is a 240-MHz 32-bit RXv2 microcontroller with single-precision IEEE-754 FPU, 4-MB on-chip code flash, 512-KB SRAM (including 32-KB ECCRAM), and integrated IEEE 1588-compliant Ethernet MAC, high-speed USB 2.0 with battery charging, CAN, SD host interface, and 12-bit dual A/D converters. It targets industrial automation gateways requiring deterministic real-time control, secure connectivity, and multi-protocol I/O.
For engineers reviewing the R5F571MFCDLK#20 datasheet, R5F571MFCDLK#20 pinout, R5F571MFCDLK#20 application, or R5F571MFCDLK#20 equivalent, key selection criteria include its 177-pin TFLGA package, dual Ethernet MAC support, 240-MHz CPU performance (480 DMIPS), hardware AES/SHA encryption, and IEC60730 safety features for certified embedded systems.
Technical Context
The R5F571MFCDLK#20 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU). It executes floating-point and DSP instructions per IEEE 754 and supports little- or big-endian data arrangement.
Its clock system integrates PLL, HOCO/LOCO oscillators, and independent peripheral clocks-PCLKA up to 120 MHz for Ethernet/USB/AES, PCLKB up to 60 MHz for timers/ADC, and dedicated IWDT clock at 120 kHz. Power management includes four low-power modes and battery-backed RTC operation via VBATT.

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 |
|---|---|---|---|
| R5F571MLCDLK#20 | Same RX71M core, identical 177-pin TFLGA package, but 2-MB code flash and 256-KB SRAM. | Suitable for cost-sensitive gateways with reduced firmware footprint and fewer concurrent tasks. | Select when application firmware fits within 2 MB and ECC RAM requirement is relaxed. |
| R5F572MFHDFP#30 | Higher-pin-count 216-pin LQFP variant with same 4-MB flash/SRAM, but adds parallel data capture (PDC) and removes USB HS. | Better suited for CMOS camera-based vision inspection systems needing PDC, not USB-hosted peripherals. | Choose only if PDC interface is required and USB 2.0 HS functionality is unnecessary. |
Compared with R5F571MFCDLK#20, the R5F571MLCDLK#20 offers lower memory capacity at reduced cost for simpler edge nodes, while R5F572MFHDFP#30 trades USB HS for PDC to serve machine vision use cases - neither is pin-compatible, and both require PCB redesign.

Yes, the R5F571MFCDLK#20 includes a dedicated PTP controller (EPTPCa) compliant with IEEE 1588-2008. It performs hardware timestamping on Ethernet frames at the MAC layer, supporting transparent clock and boundary clock modes - essential for sub-microsecond synchronization in industrial motion control and test equipment.
What package type and pin count does the R5F571MFCDLK#20 use?
The R5F571MFCDLK#20 uses the PTLG0177KA-A package: a 177-pin thin fine-pitch land grid array (TFLGA) measuring 8 mm × 8 mm with 0.5-mm pitch. This compact, thermally efficient package supports high I/O density and is qualified for industrial temperature range (–40°C to +105°C).
How many Ethernet MAC modules does the R5F571MFCDLK#20 integrate?
The R5F571MFCDLK#20 integrates two independent IEEE 802.3-compliant Ethernet MAC modules (ETHERC), each supporting 10/100 Mbps full- and half-duplex operation with MII/RMII interfaces. Both MACs connect to the EPTPCa block for IEEE 1588 timestamping and share the 3-channel EDMAC for zero-copy packet handling.
Is hardware encryption available on the R5F571MFCDLK#20?
Yes, the R5F571MFCDLK#20 includes optional hardware acceleration for AES (128/192/256-bit), DES/TDES, and SHA-1/224/256/HMAC cryptographic functions.
