Renesas R-IN32M3 and port´s communications technology enable for Industrial Networking (EtherCAT, PROFINET, Ethernet/IP and CAN/CANopen)
Presented by Renesas Alliance Gold Member port GmbH
Renesas‘ R-IN32M3 Industrial Ethernet Controller supports a wide range of Industrial Ethernet protocols. Optimized Design-In options, focussing on Low Power Design and an rich set of on-chip accessories qualify the R-In32M3 as powerful, compact and ressource consumption optimzed unit, that adds only low cost to the BOM. The intelligent integration of Hardware Accelerators create a significantly improved overall power than comparable CPU-Designs without Hardware Accelerators could provide.
The following communication technologies are available for the R-IN:
- PROFINET
- CANopen
- Ethernet / IP
- EtherCAT
- CC-LINK IE (on request)
With port's technology your applications are prepared for the upcoming challenges of the future "Industry 4.0".
