Renesas R5F572NDDGFP#30

Overview

R5F572NDDGFP#30 from Renesas Electronics is a 32-bit RXv3 core microcontroller in the RX72N Group, featuring 4 MB flash memory, 1 MB SRAM, and integrated Ethernet MAC with IEEE 1588 support. It operates at up to 240 MHz, includes dual CAN FD controllers, USB 2.0 FS/HS device/host/OTG, and supports functional safety (IEC 61508 SIL3-ready). It is deployed in industrial PLCs and motion control systems requiring deterministic real-time response and networked I/O.

For engineers reviewing the R5F572NDDGFP#30 datasheet, R5F572NDDGFP#30 pinout, R5F572NDDGFP#30 application, or R5F572NDDGFP#30 equivalent, key selection criteria include Ethernet timing precision (IEEE 1588 v2 hardware timestamping), dual CAN FD bandwidth allocation, flash ECC coverage scope, SRAM parity configuration, and peripheral clock domain isolation for mixed-criticality tasks.

Technical Context

The R5F572NDDGFP#30 implements the RXv3 CPU core with 6-stage superscalar pipeline, supporting single-precision and double-precision floating-point units (FPU/DFPU) compliant with IEEE 754. Its system architecture includes a multi-layer AXI bus matrix enabling concurrent access to flash, SRAM, and peripherals without arbitration stalls.

Real-time performance is enhanced by a 24-channel event link controller (ELC) that routes peripheral events directly to timers, ADCs, or DMA without CPU intervention, and a 32-channel DMAC with scatter-gather capability and peripheral synchronization triggers.

FAQ

What is the maximum operating frequency of the R5F572NDDGFP#30?

The R5F572NDDGFP#30 operates at a maximum CPU frequency of 240 MHz, achieved using an on-chip PLL with external crystal or oscillator input. This frequency is sustained across the full industrial temperature range (−40°C to +85°C) with appropriate power supply decoupling and thermal management. The R5F572NDDGFP#30 achieves 415.5 CoreMark/MHz at this speed, confirming its real-time processing capability for demanding control loops.

Does the R5F572NDDGFP#30 support IEEE 1588 Precision Time Protocol?

Yes, the R5F572NDDGFP#30 integrates a hardware IEEE 1588 v2 timestamping engine within its Ethernet MAC, enabling sub-microsecond timestamp accuracy on transmit and receive frames. This capability is essential for time-synchronized applications such as distributed motion control and industrial Ethernet protocols like EtherCAT and PROFINET IRT. The R5F572NDDGFP#30 does not require external timestamping ICs or software-based correction.

How much on-chip flash and SRAM does the R5F572NDDGFP#30 include?

The R5F572NDDGFP#30 includes 4 MB of on-chip flash memory with error-correcting code (ECC) and 1 MB of SRAM with parity protection. Both memories support background operation during read/write, and the flash includes region-based security locking. These capacities allow for dual-bank firmware updates, real-time data buffering, and complex control algorithms - all verified in the R5F572NDDGFP#30 datasheet and RX72N Group User's Manual Hardware.

What communication interfaces are integrated into the R5F572NDDGFP#30?

The R5F572NDDGFP#30 integrates dual CAN FD controllers (up to 8 Mbps), USB 2.0 Full-Speed and High-Speed device/host/OTG, 10/100 Ethernet MAC with MII/RMII, six UARTs, four I²C buses, and two SPI interfaces. All interfaces support DMA and interrupt-driven operation. This comprehensive set enables the R5F572NDDGFP#30 to serve as a central hub in heterogeneous industrial networks without external bridge ICs.

Is the R5F572NDDGFP#30 qualified for functional safety applications?

Yes, the R5F572NDDGFP#30 is designed to support IEC 61508 SIL3 and ISO 13849 PL e compliance, with features including lockstep CPU option, flash/SRAM BIST, safety monitor timer, and dual independent watchdogs. Renesas provides certified safety manuals and FMEDA reports for the R5F572NDDGFP#30. These capabilities are documented in the RX72N Group Functional Safety Manual and confirmed in the R5F572NDDGFP#30 product definition.
