Overview
MC-10287BF1-HN4-M1-A from Renesas is an Industrial Ethernet LSI featuring an Arm® Cortex®-M3 core running at 100 MHz, integrated Real-Time OS Accelerator, 768 KB instruction RAM with ECC, 512 KB data RAM with ECC, and dual 10/100/1000 Mbps Ethernet MACs with built-in 2-port switch - deployed in programmable logic controllers for deterministic motion control networks.
For engineers reviewing the MC-10287BF1-HN4-M1-A datasheet, MC-10287BF1-HN4-M1-A pinout, MC-10287BF1-HN4-M1-A application, or MC-10287BF1-HN4-M1-A equivalent, this page delivers verified technical context, validated pin functions, real-world industrial use cases, and confirmed alternative parts for CC-Link IE Field and EtherCAT slave implementations.
Technical Context
The MC-10287BF1-HN4-M1-A implements a dual-bus architecture: a 32-bit system bus at 100 MHz for CPU and peripheral access, and a dedicated 128-bit communication bus at 100 MHz for hardware-accelerated network processing. Its Real-Time OS Accelerator offloads μITRON 4.0 scheduling and interrupt handling, reducing CPU usage during high-frequency EtherCAT or CC-Link IE frame processing.
It integrates two independent Gigabit Ethernet MACs (GMII/MII), each with dedicated DMA channels and buffer allocation logic, supporting simultaneous full-duplex operation on both ports. The device supports IEEE 802.3 compliant 10/100/1000BASE-TX and includes hardware timestamping, priority queue management, and VLAN tag insertion/removal per port.
