Product details
Overview
R5F572NDHDLK#20 from Renesas is a 32-bit RXv3 microcontroller operating at up to 240 MHz, featuring 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, motor control gateways, and networked edge devices requiring deterministic real-time performance.
For engineers reviewing the R5F572NDHDLK#20 datasheet, R5F572NDHDLK#20 pinout, R5F572NDHDLK#20 application, or R5F572NDHDLK#20 equivalent, key selection criteria include IEEE 1588 PTP timing accuracy, dual-bank flash for safe firmware updates, 182 GPIOs with 5-V tolerance, and hardware-accelerated trigonometric (TFU) and encryption (TSIP/AES) functions - all within a 176-pin LFBGA package rated for –40°C to +105°C.
Technical Context
The R5F572NDHDLK#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 PLLs for ICLK (240 MHz), PCLKA (120 MHz), and PCLKB (60 MHz), enabling independent domain scaling for CPU, Ethernet/USB peripherals, and timers/ADCs.
Memory architecture comprises 4 MB dual-bank code flash (no-wait ≤120 MHz), 32 KB data flash (100k erase cycles), 1 MB SRAM split into 512 KB high-speed RAM and 512 KB expansion RAM, plus 32 KB ECC RAM and 8 KB standby RAM. Peripheral interconnect uses ELC (Event Link Controller) to route 135 internal event signals - eliminating CPU intervention for timer-triggered ADC starts or PWM dead-time compensation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F572NDDFLK#20 | Same RX72N core, but 144-pin LFQFP (PLQP0144KA-B), 2 MB flash, 512 KB SRAM - smaller footprint, lower I/O count (136 pins). | Suitable for space-constrained designs where Ethernet and full CAN count are not required. | Select when PCB area is limited and peripheral count can be reduced - no pin compatibility with R5F572NDHDLK#20. |
| R5F572MDDFLK#20 | RX72M Group variant: identical package/pinout, but lacks IEEE 1588 PTP, GLCDC, DRW2D, and SDHI - optimized for motor control only. | Targeted at cost-sensitive inverter drives without HMI or networked diagnostics. | Choose for pure motor control applications where Ethernet timestamping and graphics are unnecessary - pin-compatible but functionally reduced. |

The R5F572NDHDLK#20 integrates 4 MB of dual-bank code flash memory (enabling background programming and safe bank swapping), 32 KB of reprogrammable data flash (rated for 100,000 erase cycles), 1 MB of SRAM (split into 512 KB high-speed RAM and 512 KB expansion RAM), 32 KB of ECC RAM with SEC-DED protection, and 8 KB of battery-backed standby RAM. All memory blocks are accessible without wait states at their respective maximum clock frequencies.
Which communication interfaces does the R5F572NDHDLK#20 support for industrial networking?
The R5F572NDHDLK#20 supports multiple industrial networking interfaces: dual-channel Ethernet MAC compliant with IEEE 1588, three independent CAN 2.0B controllers (32 mailboxes each), USB 2.0 Full-Speed host/function with OTG, SD host interface (SDHI), and QSPI for serial flash. It also includes 13 serial channels (SCI/SCIi/SCIh), 3 I²C buses (up to 1 Mbps), and 3 RSPI ports - providing flexible connectivity for multi-protocol industrial gateways.
How does the R5F572NDHDLK#20 meet functional safety requirements such as IEC 60730?
The R5F572NDHDLK#20 includes dedicated hardware features for IEC 60730 Class B compliance: oscillation-stoppage detection, CRC accelerators (CRCA), windowed independent watchdog timer (IWDTa), self-diagnostic A/D converter test, register write protection, and memory ECC.
