R-IN32M4-CL3 Industrial Ethernet Communication IC

Renesas Electronics Corporation has announced the development of R-IN32M4-CL3 IC for Industrial Ethernet (IE) Communication; it delivers support for CC-Link IE Time-Sensitive Networking (TSN), a communication standard for next-generation Ethernet TSN technology. The R-IN32M4-CL3 is the first controller that supports CC-Link IE TSN which enables high speed and high precision motion control and it satisfies the strict specifications of less than one-millionth of a second time synchronization accuracy between applications, accelerating TSN support for applications such as AC servos, actuators, and vision sensors which demands high speed responsive control, as well as remote I/O widely used in network communication.


Features of R-IN32M4-CL3

  • Has an R-IN engine based on an Arm Cortex-M4 core with a floating-point unit (FPU)
  • Real-time OS accelerator
  • Ethernet communication accelerator
  • A Gigabit Ethernet PHY
  • Implement real-time OS processing in hardware allows users to offload the CPU and accelerate processing speeds. 
  •  1.3MB of on-chip RAM to support high-speed, high-volume communication with no real-time OS software or external components required


With R-IN32M4-CL3 users are able to implement ultra-high speed and high precision motion control. The TSN enables seamlessly linked interoperation between information technology (IT) networks and operational technology (OT) networks, which helps in changing the production and volume of production in real-time, IT also provides flexible support for the manufacture of multiple product types in varying quantities and boosts factory productivity overall.


Renesas Electronics will provide the TCP/IP Protocol software, CC-Link IE TSN protocol software, and CC-Link IE Field protocol software essential to developers along with the driver software. Tessera Technology, Inc., one of Renesas’ partner vendors, will offer an evaluation board, and Renesas will provide a start-up manual, enabling customers to jump-start industrial application development, incorporating the new technology without delay. The R-IN32M4-CL3 also supports the existing CC-Link IE Field network protocol. Customers can use the new IC in existing networking products to expand their capabilities for next-generation network functionality simply by changing the software.


Renesas will demonstrate the R-IN32M4-CL3 at the CC-Link Partner Association booth at SPS (Small Production Solutions) 2019 in Nuremberg, Germany and at IIFES (Innovative Industry Fair for Exec Solutions) 2019 in Tokyo, Japan. Renesas will begin mass production orders for the R-IN32M4-CL3 starting February 2020.
