Microchip Embedded Wi-Fi Transceivers for Machine-to-Machine Communications

Microchip Technology, a leading Flash-IP, microcontroller, and analog and solutions vendor, has announced the introduction of its agency-certified, state-of-the-art MRF24WB0MA/MB embedded Wi-Fi transceiver modules at the Chicago-based Embedded Systems Conference.

The firmware of the IEEE 802.11 module has user-friendly API driver interface to the 16-, 16- or 8-bit PIC microcontrollers and the free TCP/IP Protocol stack of Microchip.


The ubiquitous Wi-Fi infrastructure is being increasingly leveraged by the embedded designers for facilitating wireless communication for a wide range of remote control and monitoring and control, as well as machine-to-machine applications like smart-energy monitors.

The embedded, low-power MRF24WB0MA/MB Wi-Fi modules of Microchip have eliminated the expense and complexity of developing RF circuitry and procurement of the agency certification, to render the ‘Internet of Things’ possible. In addition, Microchip has also enhanced its free TCP/IP stack, and provides free ZeroConfig and EZconfig utility protocols, for easy configuring and commissioning of Wi-Fi networks.

The MRF24WB0MA PICtail Plus/PICtail/ Daughter Board have been developed by Microchip for enabling development with the Wi-Fi module. This daughter board can be plugged into the and Explorer 16 and 2 boards to easily facilitate modular development with many 32-bit PIC18, 16-bit PIC24 and 8-bit PIC32 MCUs, and the dsPIC DSCs.

Steve Caldwell, director of RF Products Division of Microchip, informed that Wi-Fi is fast emerging as the standard of choice for including remote Internet access capability in to embedded products.
