R-IN32M3 - Multi-Protocol Industrial Ethernet

RUN the R-IN! Industrial Ethernet Controllers

Industrial Ethernet at its best, Renesas Industrial Network Controllers: the R-IN32M3 Series
Industrial Ethernet controllers with multi-protocol support

The R-IN32M3 series of Industrial Ethernet controllers is designed to support a broad range of industrial Ethernet protocols. Optimized integration options, emphasis on low power design and a high level of integration make it a very powerful, compact, power optimized device with a low overall bill of material cost. Smart integration of dedicated hardware accelerators allow to offer significant more processing power for applications than similar CPU designs without such accelerators.

Key features

  • ARM® Cortex™-M3 based CPU subsystem clocked at 100MHz clock
  • Hardware offload engines take significant load from the main CPU
    • Hardware Real-time OS Accelerator (HW-RTOS)
    • Hardware Ethernet Accelerators (IP/TCP/UDP Check Sum, Header ENDEC, Buffer manager)
  • 1.3M bytes of on-chip RAM
  • 2-port Real-Time Gigabit Switch, supports cut-through and store&forward operating modes as well as IEEE1588 PTP and Device-Level-Ring (DLR) protocols
  • EtherCAT and CC-Link IE Field slave controller in hardware
  • CANopen/DeviceNet and CC-Link fieldbuses on-chip
  • Lots of peripherals and GPIOs

 

R-IN32M3 Series: Drastic reduction of CPU processing time per network frame

 
The R-IN32M3 comes in 2 flavors: one with EtherCAT (R-IN32M3-EC) and one with CC-Link IE (R-IN32M3-CL) support in hardware. Both versions include the real-time switch.

About the Connector

Although ARM-compatible connectors include 20-pin full-pitch, 20-pin half-pitch, 10-pin half-pitch, and 38-pin Mictor, the R-IN32M3 development kit supports 20-pin half-pitch only.
