R-IN32M3 series of industrial Ethernet communication chips with support for multiple communication protocols have application specific standard ICs (ASSPs) that provide high-speed operation with the basic function of the real-time OS in hardware to implement high-speed real-time response and high-precision communication control for industrial Ethernet communication. It integrates a slave controller supporting CC-Link IE Field as a circuit. It also features an ARM Cortex-M3 (100 MHz) 32-bit RISC CPU, a media access control (MAC) with low-latency 2-port switch function required by industrial Ethernet protocols, and large on-chip memory.
