Renesas R5F571MLDDFC#30

Overview

R5F571MLDDFC#30 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 - deployed in industrial gateways requiring deterministic real-time networking, secure firmware updates, and multi-protocol fieldbus coexistence.

For engineers reviewing the R5F571MLDDFC#30 datasheet, R5F571MLDDFC#30 pinout, R5F571MLDDFC#30 application, or R5F571MLDDFC#30 equivalent, key selection criteria include dual 10/100 Mbps Ethernet with PTP timestamping, high-speed USB 2.0 host/function with battery charging support, CAN FD-capable triple CAN modules, and IEC 60730 safety features including CRC, oscillation-stop detection, and A/D self-diagnosis.

Technical Context

The R5F571MLDDFC#30 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: 8 channels; EXDMACa: 2 channels) and a dedicated Ethernet DMA (EDMACa: 3 channels) to offload frame processing from the CPU while maintaining deterministic latency for time-sensitive protocols.

Clock domain partitioning separates ICLK (up to 240 MHz for CPU), PCLKA (up to 120 MHz for Ethernet/USB/AES), PCLKB (up to 60 MHz for timers/I/O), and dedicated ADCLKs (PCLKC/PCLKD) - enabling concurrent high-speed peripheral operation without CPU contention. The ELC (Event Link Controller) provides hardware-level inter-module triggering, eliminating software interrupt latency for synchronized PWM generation, A/D start, and RTC capture events.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F571MLDDFC#30?

The R5F571MLDDFC#30 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, variable-length instruction set, and dual multiply-and-accumulate units. The R5F571MLDDFC#30 sustains this performance with zero wait states on code flash up to 120 MHz and leverages background operation for concurrent flash programming and execution.

Does the R5F571MLDDFC#30 support IEEE 1588 Precision Time Protocol?

Yes, the R5F571MLDDFC#30 integrates a dedicated IEEE 1588-compliant PTP controller (EPTPCa) linked directly to its dual Ethernet MAC modules. It supports hardware timestamping of ingress and egress Ethernet frames with sub-microsecond accuracy, synchronized to internal MTU3 or GPT timers. The R5F571MLDDFC#30 also provides PTP event message filtering and transparent clock functionality required for industrial time-sensitive networking.

How many CAN interfaces does the R5F571MLDDFC#30 include, and what standards do they support?

The R5F571MLDDFC#30 includes three independent CAN modules, each compliant with ISO 11898-1 for standard and extended frame formats at bit rates up to 1 Mbps. Each module provides 32 dedicated mailboxes with configurable acceptance filtering and loopback self-test modes. These CAN interfaces operate autonomously with DMA-assisted message buffering, and the R5F571MLDDFC#30 supports concurrent operation across all three channels without CPU overhead.

What safety certifications and features does the R5F571MLDDFC#30 support for IEC 60730 compliance?

The R5F571MLDDFC#30 includes hardware features required for Class B compliance under IEC 60730: oscillation-stoppage detection, dedicated CRC calculation unit, windowed independent watchdog timer (IWDTa), A/D converter self-diagnostic function, and register write protection. These capabilities are documented in Renesas' IEC 60730 safety manual (R01UM0574EJ0100) and eliminate the need for external safety monitors when properly implemented in the R5F571MLDDFC#30-based design.

What is the package type and pin count of the R5F571MLDDFC#30?

The R5F571MLDDFC#30 uses the PLQP0176KB-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array measuring 24 × 24 mm with 0.5-mm ball pitch. This package supports 127 general-purpose I/O pins (19 with 5-V tolerance), dedicated reset and clock inputs, dual Ethernet MII interfaces, high-speed USB differential pairs, and three CAN transceiver I/O sets - all mapped to validated land patterns per Renesas' hardware design guidelines.
