IEEE802.15.4 wireless module and certified ZigBee PRO stack

Microchip has announced two additions to its IEEE802.15.4 and ZigBee portfolio for short-range, low data-rate embedded wireless networking. The MRF24J40MB is the company’s second 2.4GHz RF surface-mounted transceiver module. The module offers +20dBm of receive sensitivity via an integrated LNA (low noise amplifier) to the IEEE802.15.4 compliant transceiver, PCB antenna and discrete matching circuitry. On the software side, the company’s newly certified ZigBee PRO protocol stack provides another option for IEEE 802.15.4-based wireless networks using the company’s PIC MCUs. The combination of the company’s ZigBee PRO stack, the MRF24J40 transceiver radio or transceiver modules and any of its 16bit PIC24 MCUs or dsPIC33 DSCs forms the company’s ZigBee PRO compliant platform. Designers can integrate the MRF24J40MB transceiver module with appropriate 16bit PIC24 MCUs, dsPIC DSCs and 32bit PIC32 MCUs, by using the MRF24J40MB PICtail Plus daughter board. This AC163028-2 daughter board is designed to plug into the Explorer 16 modular development board, which has processor plug-in modules for all of the company’s 16 and 32bit families.
