CONNECT IT! ETHERNET RZ/N1S-DB
Introduction
RZ/N1 is a family of scalable ARM® based industrial Ethernet switches. Due to the integrated performant
ARM® Cortex®-A7 CPU, they are ideal choice for building products such as Programmable Logic Controllers
(PLC), complex remote-IO slaves, industrial switches, gateways or operator terminals.
RZ/N1 Family consists of three devices, out of which the RZ/N1S, is an industrial ethernet communication
System on Chip with a 3 or 5-ports, depending on the respective chosen package 324BGA/196BGA.
This guide shall assist you to quickly start with your evaluation of the RZ/N1S device on the related Solution
Kit board(s) and the Solution Kit software and documentation. It represents a short guide for the first time users
with the instructions for the first startup of the board.
In addition to this document, please be aware of the extensive documentation on RZ/N1 devices, evaluation
boards and software that you may find in the Solution Kit Documentation directory.
The Solution Kit boards can solely be used for evaluation purposes. It is not allowed to use the boards for
commercial purposes.
