Product details
Overview
R5F572NNDDBG#20 from Renesas is a 32-bit RXv3 microcontroller with 240 MHz CPU, 4 MB on-chip flash, 1 MB SRAM (including 32 KB ECC RAM), IEEE-754 double-precision FPU, Ethernet MAC (IEEE 1588), CAN, USB 2.0 FS, and SDHI - designed for industrial HMI, gateway, and real-time control applications requiring deterministic timing and functional safety support.
For engineers reviewing the R5F572NNDDBG#20 datasheet, R5F572NNDDBG#20 pinout, R5F572NNDDBG#20 application, or R5F572NNDDBG#20 equivalent, key selection criteria include its 224-pin LFBGA package, dual-bank flash for safe firmware updates, 136 I/O pins with 5-V tolerance, integrated TSIP encryption, and IEC60730-compliant self-test features for Class B certification.
Technical Context
The R5F572NNDDBG#20 implements the RXv3 CPU core with 16 general-purpose 32-bit registers, double-precision FPU (64-bit IEEE-754), and collective register bank save for fast context switching. It supports little-endian or big-endian data arrangement and executes instructions at up to 240 MHz with no wait states below 120 MHz on flash access.
Its clock system includes main crystal oscillator (8–24 MHz), PLLs for system/peripheral clocks, and dedicated IWDT oscillator. Peripheral clocks are independently configurable: ICLK up to 240 MHz, PCLKA up to 120 MHz (for ETHERC, GPTW, GLCDC), PCLKB up to 60 MHz (for WDT, TMR, CMT), enabling precise timing partitioning across real-time subsystems.
