Microchip Introduces MiWi Peer-to-Peer Wireless Protocol Stack

Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, announced the MiWi[tm] Peer-to-Peer (P2P) Wireless Protocol Stack, which is based upon the IEEE 802.15.4[tm] specification. Available as a free download from Microchip’s new online Wireless Design Center, the small-footprint, proprietary stack complements the new MRF24J40MA 2.4 GHz FCC-certified transceiver module and is targeted for low-cost, low-power applications, such as sensors, remote control, lighting and metering.

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.

“Microchip is providing this new IEEE 802.15.4 based proprietary wireless protocol stack to enable simple, low-cost, low-power, peer-to-peer communication,” said Steve Caldwell, director of Microchip’s Radio Frequency Products Division. “With the addition of the MiWi P2P stack, Microchip now has three free wireless-protocol stacks to complement our new 2.4GHz, IEEE 802.15.4 FCC-certified MRF24J40MA module.”

Stack Availability & Related Development Tools
The MiWi P2P stack and Microchip’s ZigBee and MiWi stacks can be downloaded for free from Microchip’s online Wireless Design Center at www.microchip.com/wireless. The stacks can be used with Microchip’s FCC-certified MRF24J40MA FCC-certified radio-frequency transceiver module, also announced today. Servicing the 2.4 GHz unlicensed Industrial, Scientific and Medical (ISM) short-range wireless frequency band for the IEEE 802.15.4[tm] specification using ZigBee® or proprietary wireless-protocol systems, the module is available for purchase at www.microchipdirect.com today, for $8.99 each in 1,000-unit quantities.

Microchip's PICDEM Z Demonstration KitDesigners can also use Microchip’s PICDEM[tm] Z Demonstration Kit (Part # DM163027) with all of the Company’s free stacks and MRF24J40MA module. The kit includes a pair of development boards with a PIC18LF4620 MCU, along with the ZENA[tm] Network Analyzer and wireless network configuration utility (Part # DM183023). The kit is available today at www.microchipdirect.com, for $269. The ZENA Network Analyzer can also be purchased by itself at www.microchipdirect.com, for $129.99.
