RZ/N Series MPUs Renesas Electronics RZ/N Series Microprocessors (MPUs) are scalable and high-performance Arm®-based communication devices that support multiple industrial network protocols and redundant network technologies on a single device. To simplify protocol implementation, the RZ/N Series features a unified protocol communication abstraction layer that allows the user to switch from one protocol to another quickly, all in the same platform. The RZ/N devices are ideal for many industrial applications such as intelligent gateways and protocol converters, programmable logic controllers (PLCs), remote IO units, and networked intelligent endpoints for the Industry 4.0/Industrial IoT realm of applications.
