The firmware of the agency-certified next-generation MRF24WB0MA/MB embedded Wi-Fi transceiver module incorporates an easy-to-use driver API interface for connecting to Microchip's free TCP/IP protocol stack and its 8-, 16-, or 32-bit PIC microcontrollers. Microchip's low-power embedded Wi-Fi modules are helping to usher in the Internet of Things by eliminating the complexity and cost of developing RF circuitry and obtaining agency certification. In addition, Microchip has enhanced its free TCP/IP stack and offers free delivery protocols EZconfig and ZeroConfig to simplify the commissioning and configuration of Wi-Fi networks.

 

Transceiver modules 1pThe new MRF89XA transceiver offers an extremely low receive current of 3 mA, a 12.5 dBm power amplifier for long-range transmission, and a low-noise amplifier for improved receive sensitivity of -113 dBm. An integrated packet selector with a 64-byte FIFO for transmit and receive buffering further extends battery life in 868, 915, and 950 MHz sub-GHz wireless networks. The 868 MHz MRF89XAM8A and 915 MHz MRF89XAM9A transceiver modules accelerate design cycles by eliminating the complexity of RF circuitry design and the cost of obtaining agency certification.
Microchip has also created the MRF24WB0MA PICtail™/PICtail Plus daughterboard for development with the new Wi-Fi module. The MRF89XAM8A and MRF89XAM9A PICtail/PICtail Plus daughterboards are scheduled to be available in this third quarter, for the development of 868 and 915 MHz applications, respectively.
