Overview
R5F572NNHDBG#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 - deployed in industrial HMIs, motor control gateways, and real-time PLC edge nodes.
For engineers reviewing the R5F572NNHDBG#20 datasheet, R5F572NNHDBG#20 pinout, R5F572NNHDBG#20 application, or R5F572NNHDBG#20 equivalent, key selection considerations include IEEE 1588 PTP timing accuracy, dual-bank flash for safe firmware updates, 182 GPIOs with 5-V tolerance, CAN FD readiness via software configuration, and hardware-accelerated trigonometric functions for motion control loops.
Technical Context
The R5F572NNHDBG#20 implements the RXv3 CPU core with full 240 MHz operation, supporting 1396 CoreMark and double-precision floating-point arithmetic per IEEE 754. Its memory subsystem includes 4 MB dual-bank code flash (with background programming), 1 MB SRAM (split into 512 KB fast-access + 512 KB expansion), and 32 KB ECC-protected RAM for safety-critical data.
Peripherals are clocked across four domains: ICLK (up to 240 MHz for CPU), PCLKA (up to 120 MHz for ETHERC/GPTW/GLCDC), PCLKB (up to 60 MHz for timers/SCI), and PCLKC/PCLKD (60 MHz for A/D converters). The device integrates two independent Ethernet MAC channels with EPTPCb for hardware timestamping and EDMACa for zero-copy frame handling.

What is the maximum operating frequency and CoreMark score of the R5F572NNHDBG#20?
The R5F572NNHDBG#20 operates at a maximum frequency of 240 MHz and achieves 1396 CoreMark points under benchmark conditions. This performance stems from the RXv3 CPU core's optimized pipeline, double-precision FPU, and zero-wait-state access to 512 KB of SRAM at full speed - making R5F572NNHDBG#20 suitable for computationally intensive tasks like real-time motion control and protocol stack processing.
Does the R5F572NNHDBG#20 support IEEE 1588 Precision Time Protocol, and how is it implemented?
Yes, the R5F572NNHDBG#20 includes dedicated hardware for IEEE 1588-2008 PTP via the EPTPCb module, which provides hardware timestamping on Ethernet frames with sub-100 ns resolution. Timestamps are injected directly into transmit/receive descriptors handled by EDMACa, eliminating software latency and CPU overhead - a key enabler for time-sensitive industrial automation using R5F572NNHDBG#20 as a master clock node.
What flash and RAM resources does the R5F572NNHDBG#20 provide, and how are they allocated?
The R5F572NNHDBG#20 integrates 4 MB of dual-bank code flash (enabling background programming and safe firmware updates), 1 MB of SRAM (512 KB fast-access + 512 KB expansion), 32 KB of ECC-protected RAM, and 8 KB of battery-backed standby RAM. This memory architecture supports concurrent real-time control, secure data logging, and HMI rendering - all within a single R5F572NNHDBG#20 device without external memory.
How many Ethernet MAC channels and CAN interfaces does the R5F572NNHDBG#20 support?
The R5F572NNHDBG#20 features two independent Ethernet MAC channels compliant with IEEE 802.3 10/100 Mbps and three CAN modules compliant with ISO 11898-1, each supporting 32 mailboxes. This combination allows R5F572NNHDBG#20 to serve as a converged edge node - for example, bridging PROFINET over one Ethernet port while running CANopen diagnostics on field sensors via the second Ethernet and all three CAN channels.
Is the R5F572NNHDBG#20 qualified for functional safety standards such as IEC 60730?
Yes, the R5F572NNHDBG#20 includes multiple hardware features certified for IEC 60730 Class B compliance: oscillation-stop detection, CRC accelerator, windowed IWDT, register write protection, and ADC self-diagnostic function. These capabilities reduce software certification effort and enable R5F572NNHDBG#20 to be deployed in safety-related industrial controls - including motor drives and energy metering systems - with documented failure modes and mitigation paths.
