DATA SHEET Ethernet communication continues to spread rapidly in the field of industrial automation as manufacturers seek to improve the capability, efficiency, and flexibility of their organizations. Modern Industrial Ethernet applications require high-speed real-time response, low power consumption, and high performance. These requirements are not necessarily met by traditional methods such as hard-wired Ethernet processors or dedicated high-speed CPUs. Renesas' R-IN32M3 series of large-scale integrated circuits (LSI) are specifically tailored to meet the demands of Industrial Ethernet applications. Key features include: • • • • • • • • • High-speed, real-time, deterministic, low-latency, low-jitter response for real-time applications Low power consumption Integrated ARM Cortex-M3 core for flexibility Integrated Real-Time OS Accelerator with support for μITRON version 4.0 Integrated Gigabit Ethernet MAC (R-IN32M3-CL only) Integrated 10/100Mbps EtherPHY (R-IN32M3-EC only) Dedicated, DMA controller and buffer for the network processor High performance with low CPU usage by offloading functions to Real-Time OS Accelerator Multiple timers, serial interfaces, general purpose I/O (GPIO), external memory interfaces Product Lineup Renesas’ R-IN32M3 series includes the following two devices: Table1.1 R-IN32M3 Product Lineup Product name R-IN32M3 with built-in EtherCAT R-IN32M3 with built-in CC-Link IE Field (Intelligent device stati
