To support the growth of the new Industrial Internet of Things (IoT) and Industry 4.0 initiatives, industrial designers are leveraging Ethernet-based industrial networking protocols such as EtherCAT®, PROFINET® and Ethernet/IP™ to enable real-time connectivity in the factory floor, resulting in improved operational efficiencies and reduced costs.


The challenge is selecting a cost-effective platform that supports the leading protocols, while implementing technologies to improve management of complex real-time operations.


The R-IN32M3 Series of multi protocol communication LSIs realizing high-speed real-time response and low power consumption, for which demand is increasing in industrial Ethernet communications, have the following two major features.


1. Integrated real-time OS accelerator (HW-RTOS) and Ethernet accelerator

One of the most distinctive features of the R-IN32M3 is the 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. Because the hardware in the new R-IN32M3 Series covers heavy load operations for the CPU, the combination of the CPU and HW-RTOS result in ultra-high-speed real-time responsiveness five to ten times that of a conventional software real-time OS. In addition, the fluctuation caused by inconsistencies in the operation time with conventional CPU processing is reduced substantially from one-fifth to one-tenth of the previous level.

2. Multi-protocol support (CC-Link IE, EtherCAT, EtherNet/IP, etc.)

The R-IN32M3 Series supports various industrial Ethernet protocols, including CC-Link IE Field and EtherCAT, and conventional open network protocols.


  • Ethernet protocols:CC-Link IE Field1, EtherCAT2, EtherNet/IP, PROFINET (RT), Modbus TCP, and FL-net (TBD)
  • Open network protocols:CC-Link, CANopen, DeviceNet, Modbus RTU/ASCII



  1. Supported by R-IN32M3-CL only.
  2. Supported by R-IN32M3-EC only.

Hardware Design Support

Title Description

IBIS standard simulation data is required for high-speed board design and can be used to run simulations to examine and troubleshoot issues such as waveform reflection, ringing, and so on, before producing the actual board.

BSDL is a data input format supported by most IEEE 1149.1 (JTAG)-compliant tools. The automatic test pattern generation (ATPG) and automatic test equipment functions of these tools facilitate testing.
