Overview
R5F571MLDDBG#20 from Renesas is a 32-bit RXv2 microcontroller with 240 MHz CPU frequency, 480 DMIPS performance, on-chip FPU, 4 MB code flash, 512 KB SRAM, and integrated IEEE 1588-compliant Ethernet MAC - designed for industrial real-time control and networked embedded systems requiring deterministic timing and secure connectivity.
For engineers reviewing the R5F571MLDDBG#20 datasheet, R5F571MLDDBG#20 pinout, R5F571MLDDBG#20 application, or R5F571MLDDBG#20 equivalent, key selection criteria include its 176-pin LFBGA package, dual Ethernet MAC support, high-speed USB 2.0 with battery charging, CAN FD-capable triple CAN modules, and IEC60730 safety features for functional safety certification.
Technical Context
The R5F571MLDDBG#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 with 8 channels, EXDMACa with 2 channels) and a dedicated Ethernet DMA (EDMACa with 3 channels) to offload data movement from the CPU during high-throughput network operations.
Its clock system supports multiple independent domains: 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 and serial interfaces. The device includes hardware-accelerated cryptographic engines (AES-128/192/256, SHA-224/256, HMAC) and ECC-protected 32 KB RAM for safety-critical data integrity.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F571MLDDBG#20?
The R5F571MLDDBG#20 operates at a maximum frequency of 240 MHz and delivers 480 DMIPS performance. This is achieved through the RXv2 CPU core's 5-stage pipeline and optimized instruction set, enabling real-time deterministic execution for industrial control tasks. The R5F571MLDDBG#20 maintains this performance across its full voltage range (2.7–3.6 V) and temperature range (–40°C to +85°C).
Does the R5F571MLDDBG#20 support IEEE 1588 Precision Time Protocol?
Yes, the R5F571MLDDBG#20 includes a dedicated PTP controller (EPTPCa) tightly coupled to its dual Ethernet MACs, providing hardware timestamping for IEEE 1588-2008 (PTPv2) compliant synchronization. This enables sub-microsecond clock alignment across distributed nodes - a critical requirement for time-sensitive networking in industrial automation. The R5F571MLDDBG#20 supports both one-step and two-step timestamping modes.
What package type and pin count does the R5F571MLDDBG#20 use?
The R5F571MLDDBG#20 uses the PLQP0176KB-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array (LFBGA) measuring 24 mm × 24 mm with 0.5 mm ball pitch. This package supports 127 general-purpose I/O pins with 5-V tolerance, essential for interfacing with legacy industrial sensors and actuators. The R5F571MLDDBG#20's pinout is documented in Renesas datasheet R01DS0249EJ0120, pages 112–127.
How many Ethernet MAC interfaces does the R5F571MLDDBG#20 integrate?
The R5F571MLDDBG#20 integrates two fully independent IEEE 802.3-compliant Ethernet MAC controllers, each supporting 10/100 Mbps operation in full- and half-duplex modes. Both MACs connect to the EPTPCa PTP block and EDMACa DMA controller, enabling concurrent time-synchronized traffic handling - a key differentiator for industrial gateways. This dual-MAC capability is exclusive to the 176-/177-pin RX71M variants like the R5F571MLDDBG#20.
Is the R5F571MLDDBG#20 qualified for functional safety standards such as IEC60730?
Yes, the R5F571MLDDBG#20 includes hardware features certified for IEC60730 Class B compliance, including oscillation-stoppage detection, hardware CRC calculation unit, independent watchdog timer (IWDTa) with window function, self-diagnostic A/D converter test, and register write protection. These capabilities enable developers to achieve functional safety certification without external components.
