Microchip has announced the MRF24J40MA FCC-certified Radio-Frequency (RF) transceiver module and the MiWi Peer-to-Peer (P2P) Wireless Protocol Stack, based upon the IEEE 802.15.4 specification. Together the MRF24J40MA module and MiWi (P2P) 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 (MCUs). 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 for the US (FCC), Canada (IC) and Europe (ETSI), and is expected to save designers time and money by eliminating the need to receive FCC 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 3K bytes for Microchip’s PIC microcontrollers (MCUs). 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 new MiWi P2P stack provides sleeping-node, active-scan, and energy-detect features that enable robust operation while supporting the low-power requirements of battery-operated devices.
