Renesas RZ/N1

Industrial multi-protocol implementation made easy


RZ/N1 Solution Kit – Fast prototyping for Multi-protocol Industrial Ethernet



RZ/N1 is a family of scalable ARM®-based industrial Ethernet switches. Due to the performant ARM® Cortex®-A7 CPU on board, they are the ideal choice for building Programmable Logic Controllers (PLC), industrial switches, gateways or operator terminals.


You can start evaluating RZ/N1D with the solution kit.
For further information, please contact us at: industrial-automation-eu@lm.renesas.com



RZ/N1D and RZ/N1S, are made of two building blocks integrated in a single housing.

  • The communication block is based on the proven R-IN communication engine, already implemented in R-IN32M3 and RZ/T1. It features an advanced Ethernet switch structure powered by an ARM® Cortex®-M3 CPU.
  • The application block contains a dual ARM® Cortex®-A7 core in the RZ/N1D version or a single ARM® Cortex®-A7 core in the RZ/N1S version.


RZ/N1L is the smallest product from the RZ/N1 Family. It includes only the communication block with the R-IN Engine.

To simplify protocol implementation, the RZ/N1 features a unified protocol communication abstraction layer that allows the user to quickly switch from one protocol to another, all in the same platform.



Many industrial Ethernet protocols from leading vendors have already been developed within this abstraction layer. An API towards the application software makes the communication software transparent and lets developers focus on what they know best - solving customers’ problems. Depending on the application requirements, a simple migration between a range of R-IN Engine-based chips is also possible.


RZ/N1 and TSN

The RZ/N1 Series paves the way towards the future of Industry 4.0 with the support of key Time Sensitive Network (TSN) standards. The intelligent time division multiple access (TDMA) engine with up to four queues and frame priority classification, as well as the IEEE1588 timestamping allow system developers to start implementing tight time synchronization and network traffic scheduling that is needed for the next generation connected factory networks.
