MiWi is a proprietary wireless protocol supporting peer-to-peer, star network connectivity. It was designed by Microchip Technology. MiWi uses small, low-power digital radios based on the IEEE 802.15.4 standard, and is designed for low-power, cost-constrained networks, such as industrial monitoring and control, home and building automation, remote control, wireless sensors, lighting control, and automated meter reading.

The MiWi protocol is supported on Microchip's SAMR30 (sub-gigahertz) and SAMR21 (2.4 GHz) ARM Cortex-M0+ devices and modules. Legacy MiWi protocol code supporting PIC and dsPIC microcontrollers has been frozen and is no longer recommended for new designs; however, it is still available in the Microchip Library for Applications (MLA) for the MPLAB Integrated Development Environment.
