MiWi™ Wireless Networking Protocol For Low-Cost Embedded Wireless Connectivity for Commercial and Smart Home Networks

Summary Developed to enable low-cost, commercial and smart home networks, MiWi� Protocol is Microchip’s compact, royalty-free wireless protocol designed for 802.15.4 networks. The MiWi protocol stack offers a significantly smaller footprint relative to the open standard-based ® compliant protocol stack. This enables operation in with smaller MiWi™ memory/lower cost. A typical end node requires only 20 KB of code space.

MiWi protocol enables P2P, Star and an efficient, self-healing mesh network that is a true Routing Mesh versus a flood mesh. MiWi -pro tocol is a scalable and reliable network with support for several transceivers including the single-chip SAM R21 and SAM R30 System in a Package (SiP). The MiWi protocol is used in applications such HVAC systems and alarm sensors where reliable self-healing mesh networking is needed.

Microchip’s MiWi Mesh Stack is now available for Atmel Studio 7, the Integrated Development Platform (IDP) for developing and debug- ging all AVR® and SAM applications. The Atmel Studio 7 IDP gives you a seamless and easy-to-use environment to write, build and debug your applications written in C/C++ or assembly code.

Atmel Studio 7 is available at: www.microchip.com/avr-support/atmel-studio-7 and the MiWi Mesh code is part of the latest Advanced Software Framework (ASF) release for Studio, available at: www.microchip.com/avr-support/advanced-software-framework-(asf).
