Overview
R5F572NNDGFB#10 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 supports functional safety (IEC 61508 SIL3-ready) for industrial automation and motion control applications.
For engineers reviewing the R5F572NNDGFB#10 datasheet, R5F572NNDGFB#10 pinout, R5F572NNDGFB#10 application, or R5F572NNDGFB#10 equivalent, key selection criteria include real-time performance (240 MHz CPU + FPU), integrated industrial connectivity (Ethernet + dual CAN FD), on-chip safety mechanisms (lockstep CPU, ECC on flash/SRAM), and package-specific thermal and routing constraints for the 176-pin LFBGA.
Technical Context
The R5F572NNDGFB#10 implements a superscalar RXv3 CPU core with hardware FPU and double-precision floating-point coprocessor, enabling deterministic real-time computation for servo drive algorithms and PLC logic execution. Its system architecture integrates a 64-bit AXI bus matrix, dual-channel DMAC with scatter-gather support, and dedicated peripheral buses for low-latency access to timers, ADCs, and communication peripherals.
Hardware safety features include lockstep CPU core monitoring, parity/ECC protection across all on-chip memories (flash, SRAM, cache), and independent watchdog timers with windowed operation. The device supports IEC 61508 SIL3 development via certified safety libraries and diagnostic firmware, with built-in self-test (BIST) for memory and logic blocks.
