Customers in the industrial arena often require real-time Ethernet solutions, also called industrial Ethernet. Common standards are EtherCat, Powerlink, Sercos III, ProfiNet, Modbus TCP and others.
For a low-cost Industrial Ethernet switch or similar setup with fewer calculation performance requirements, the RZ/N1S MPU is a perfect fit because of its high integration, rich interfaces and integrated 6MB RAM. The RZ/N1D features an integrated Arm® Cortex®-M3 based R-In engine that offloads the main cores by working as a dedicated Gigabit Ethernet hardware RTOS/accelerator. External Flash memory can be attached by using a dedicated, second QSPI interface.
This solution demonstrates that a low-cost industrial Ethernet switch can be produced simply with an RZ/N1S MPU, up to 5 Ethernet PHYs, and a power supply. To power this setup, two precise power rails are required and can easily be achieved using our highly integrated RAA212422 dual-output buck regulator, which features integrated MOSFETs that provide a small PCB footprint solution.
- Highly integrated, low-cost industrial Ethernet (switch) solution with R-In offload engine / HW accelerator
- Easy to use, high efficiency dual in/out DC/DC converter, providing all required voltages
- Low BOM count and small PCB space
