R5F572NDHGBD#20 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, and hardware encryption (AES-128/256, SHA, RSA). It targets industrial PLCs and motion control systems requiring real-time deterministic response and networked synchronization.

For engineers reviewing the R5F572NDHGBD#20 datasheet, R5F572NDHGBD#20 pinout, R5F572NDHGBD#20 application, or R5F572NDHGBD#20 equivalent, key selection criteria include Ethernet timing precision (IEEE 1588 v2 hardware timestamping), dual CAN FD bandwidth allocation, flash ECC protection level, SRAM retention mode current, and QSPI interface clock rate for external XIP execution.

Technical Context

The R5F572NDHGBD#20 implements the RXv3 CPU core with 6-stage superscalar pipeline, supporting both little-endian and big-endian operation via software-controlled endian switch. Its system architecture integrates a 240 MHz main PLL with independent sub-PLLs for USB, Ethernet, and audio clocks - enabling simultaneous high-speed peripheral operation without clock domain conflict.

Peripheral subsystems include a 12-bit 16-channel ADC with 0.5 µs conversion time, a 32-bit quadrature encoder interface (QEI) with 4x digital filtering, and a programmable gain amplifier (PGA) with 1–32× gain selectable per channel. All analog inputs are routed through a shared input multiplexer with configurable sampling sequence control.

FAQ

What is the maximum operating frequency of the R5F572NDHGBD#20?

The R5F572NDHGBD#20 operates at a maximum CPU frequency of 240 MHz, achieved via its on-chip PLL with external crystal input. This frequency is sustained under full peripheral load with junction temperature ≤ 105°C and VCC = 3.3 V ± 5%. The R5F572NDHGBD#20 maintains instruction throughput consistency across all operating modes, including when IEEE 1588 timestamping and dual CAN FD are simultaneously active.

Does the R5F572NDHGBD#20 support IEEE 1588 Precision Time Protocol?

Yes, the R5F572NDHGBD#20 includes full hardware IEEE 1588 v2 support with timestamp registers, PPS input capture, and event frame processing logic. It achieves sub-100 ns timestamp resolution and supports one-step and two-step clock correction modes. The R5F572NDHGBD#20's hardware implementation offloads all timestamp calculations from the CPU, ensuring deterministic behavior in time-critical industrial networks.

What package type is used for the R5F572NDHGBD#20?

The R5F572NDHGBD#20 is supplied in a 224-pin LFBGA package (15 mm × 15 mm, 0.8 mm pitch) with 209 usable I/O terminals. This package supports high-density PCB layouts and provides dedicated pin groups for Ethernet RMII, dual CAN FD, QSPI, and analog signal routing. The R5F572NDHGBD#20's pinout is fully documented in Section 1.5.1 of the RX72N Group User's Manual: Hardware (Rev.1.20).

How much on-chip flash and SRAM does the R5F572NDHGBD#20 include?

The R5F572NDHGBD#20 integrates 4 MB of on-chip flash memory with ECC protection and 1 MB of SRAM with parity checking. Flash supports read-while-write operation and secure boot verification; SRAM includes retention mode with ultra-low leakage current (≤10 µA at 25°C). These memory resources enable complex real-time applications such as multi-axis motion control with buffered trajectory planning in the R5F572NDHGBD#20.

Which communication interfaces are integrated into the R5F572NDHGBD#20?

The R5F572NDHGBD#20 integrates Ethernet MAC (10/100 Mbps with IEEE 1588), dual CAN FD controllers (up to 8 Mbps), USB 2.0 Full-Speed/High-Speed, six SCI modules, four I²C buses, and QSPI for external flash. It also features a 12-bit 16-channel ADC, 32-bit QEI, and programmable gain amplifier - making it a complete system-on-chip for networked industrial controllers. All interfaces are accessible via the R5F572NDHGBD#20's 224-pin LFBGA package with dedicated routing zones.
