Renesas R5F572NDDDBD#20

Overview

R5F572NDDDBD#20 from Renesas is a 32-bit RXv3 microcontroller with 240 MHz CPU, double-precision IEEE-754 FPU, 4 MB on-chip code flash, 1 MB SRAM (including 32 KB ECC RAM), and integrated Ethernet MAC compliant with IEEE 1588. It supports CAN (3 channels), USB 2.0 FS host/function, SDHI, QSPI, and GLCDC - deployed in industrial HMIs, networked PLCs, and real-time motion control systems.

For engineers reviewing the R5F572NDDDBD#20 datasheet, R5F572NDDDBD#20 pinout, R5F572NDDDBD#20 application, or R5F572NDDDBD#20 equivalent, key selection criteria include IEEE 1588 PTP timing accuracy, dual-bank flash for safe firmware updates, 182 GPIO with 5-V tolerance, 12-bit dual A/D converters (29 total channels), and hardware encryption (AES-128/192/256 + TSIP).

Technical Context

The R5F572NDDDBD#20 implements the RXv3 CPU core with 16 general-purpose 32-bit registers, double-precision FPU (16×64-bit data registers), and collective register bank save for fast context switching. Its clock system includes dual PLLs, selectable HOCO (16/18/20 MHz), and independent PCLK domains (PCLKA up to 120 MHz for ETHERC/GLCDC, PCLKB up to 60 MHz for timers/A/D).

It integrates three DMA controllers - DMACAa (8 channels), EXDMAC (2 channels), and DTCb (1 channel) - coordinated via Event Link Controller (ELC) for zero-CPU-intervention peripheral chaining. Real-time capabilities are reinforced by GPTW (4×32-bit PWM timers), MTU3a (9-channel multifunction timer), and RTC with battery-backed time capture and leap-year correction.

FAQ

What is the maximum operating frequency and CoreMark score of the R5F572NDDDBD#20?

The R5F572NDDDBD#20 operates at a maximum frequency of 240 MHz and achieves 1396 CoreMark. This performance stems from the RXv3 CPU core's optimized pipeline, double-precision FPU, and zero-wait-state access to 4 MB code flash at ≤120 MHz - enabling real-time execution of complex control algorithms and communication stacks without throttling.

Does the R5F572NDDDBD#20 support IEEE 1588 Precision Time Protocol?

Yes, the R5F572NDDDBD#20 includes dedicated hardware in its Ethernet controller (ETHERC) and PTP module (EPTPC) to implement IEEE 1588-2008. It supports hardware timestamping of ingress/egress frames, PTP message processing, and synchronization to sub-100 ns accuracy - essential for time-critical industrial Ethernet applications like motion control and distributed I/O.

What are the flash and RAM configurations of the R5F572NDDDBD#20?

The R5F572NDDDBD#20 integrates 4 MB of on-chip code flash with dual-bank architecture, 1 MB of SRAM (512 KB no-wait ≤120 MHz), 32 KB of ECC RAM (SEC-DED), and 8 KB of battery-backed standby RAM. This memory hierarchy supports robust firmware updates, real-time data buffering, fault-tolerant logging, and RTC persistence - all critical for industrial reliability.

Which security and functional safety features does the R5F572NDDDBD#20 provide?

The R5F572NDDDBD#20 includes AES-128/192/256 and Trusted Secure IP (TSIP) for cryptographic operations, plus an IEC60730-compliant self-test suite covering oscillation-stoppage detection, CRC calculation, IWDT supervision, A/D converter diagnosis, and register write protection - enabling certification to SIL2 and PLd safety levels in industrial equipment.

What package type and pin count does the R5F572NDDDBD#20 use?

The R5F572NDDDBD#20 uses the PLBG0224GA-A package: a 224-pin Low-Profile Fine-Pitch Ball Grid Array measuring 13 mm × 13 mm with 0.8 mm ball pitch. It provides 182 general-purpose I/O pins with 5-V tolerance, open-drain capability, and configurable pull-up resistors - ideal for interfacing with diverse industrial sensors and actuators.
