IEEE802.15.4 solution for wireless networking

17 September 2008 Telecoms, Datacoms, Wireless, IoT

Microchip has developed the MRF24J40MA FCC-certified RF transceiver module and the MiWi Peer-to-Peer (P2P) wireless protocol stack, based upon the IEEE 802.15.4 specification. Together, the module and stack can target a variety of wireless networking applications, such as industrial monitoring and control, home and building automation, remote control, low-power wireless sensor networks, lighting control and automated meter reading.

Providing a complete short-range IEEE 802.15.4 wireless networking solution, the MRF24J40MA transceiver module is surface mountable and can be used with hundreds of 8-bit, 16-bit, or 32-bit PIC microcontrollers. It includes discrete biasing components and an integrated PCB antenna to be used in sensor and control network environments. The module is fully regulatory-agency certified by the FCC and ETSI, and is expected to save designers time and money by eliminating the need to receive certification for their wireless products.

The MiWi P2P protocol stack supports star and peer-to-peer wireless-network topologies with an ultra-small code implementation of 3 KBytes. As a result, the stack provides short-range wireless customers with hundreds of possible MCU implementations for applications that require simple node-to-node communication. Additionally, the stack provides sleeping-node, active-scan and energy-detect features that enable robust operation while supporting the low-power requirements of battery-operated devices.
