Renesas R5F572MNHGFB#10

Overview

R5F572MNHGFB#10 from Renesas is a 32-bit RXv3 microcontroller with 240 MHz CPU, dual-bank 4 MB flash, 1 MB SRAM (including 32 KB ECC RAM), EtherCAT slave controller, IEEE 1588-compliant Ethernet MAC, and integrated 12-bit A/D and D/A converters - deployed in industrial motion control systems requiring deterministic real-time I/O and functional safety support per IEC 60730.

For engineers reviewing the R5F572MNHGFB#10 datasheet, R5F572MNHGFB#10 pinout, R5F572MNHGFB#10 application, or R5F572MNHGFB#10 equivalent, key selection criteria include EtherCAT slave timing compliance, dual-bank flash for safe firmware updates, 240-MHz deterministic execution with double-precision FPU, and integrated TSIP-based AES encryption for secure boot and data protection.

Technical Context

The R5F572MNHGFB#10 implements the RXv3 CPU core with hardware-accelerated double-precision IEEE-754 floating-point arithmetic, collective register bank save for fast interrupt response, and MPU-enforced memory protection. It integrates an EtherCAT Slave Controller (ESC) IP core compliant with Beckhoff ESC v10, supporting two physical ports and distributed clock synchronization.

Clock architecture includes dual PLLs: one for system clock generation up to 240 MHz (ICLK), another dedicated to Ethernet/IEEE 1588 timestamping (EPTPC). Peripheral clocks are independently configurable - PCLKA at up to 120 MHz for MTU3a, GPTW, ETHERC; PCLKB at up to 60 MHz for TMR, CMT, IWDT - enabling precise timing isolation across real-time subsystems.
