|Microchip Technology's Free ZigBee™ Protocol Stack|
CHANDLER, Ariz. — Microchip Technology Inc. announced its free ZigBee™ Protocol Stack now supports the
Uniband Electronic Corporation (UBEC) uz2400 ZigBee/IEEE802.15.4 2.4GHz RF transceiver. Embedded systems designers
can now utilize Microchip's ZigBee Stack with the UBEC uz2400 RF transceiver or the Chipcon CC2420 transceiver,
providing increased design flexibility. Microchip offers the smallest and only free (no-cost license and royalty
free) Zigbee Stack, enabling lower development and system costs. In addition, Microchip announced it has upgraded
its ZigBee Stack to version 3.3, to meet ZigBee specification version 1.0.
The ZigBee standard is an industry
protocol for wirelessly networked control and monitoring applications. According to research firm In-Stat ("802.15.4
SoC & SiP Surge as ZigBee Faces Residential Competition" by Joyce Putscher, June 2005, # IN0501836MI), there are
expected to be more than 150 million devices by 2009 taking advantage of the ZigBee protocol's low-cost, mesh and
low-power capabilities. Many engineers who wish to use the ZigBee protocol in their embedded designs, especially
those at small- and medium-sized companies, cannot afford the license fees for commercially available ZigBee stacks
and do not have the resources to develop them on their own.
"Microchip offers the smallest and
only free ZigBee Protocol Stack on the market. With support now for UBEC and Chipcon, our engineering customers can
choose the best transceiver for their applications," said Ganesh Moorthy, vice president of the Advanced
Microcontroller and Memory Division.
To make it easy for engineers to design with the ZigBee
protocol, Microchip features the PICDEM™ Z Demonstration Kit (DM163027-2), an easy-to-use evaluation and development
platform for ZigBee application designers. The kit includes all of the hardware, software source-code and printed
circuit board (PCB) layout files needed to rapidly prototype wireless products.
The PICDEM Z
development platform is based on Microchip’s PIC18 high-performance microcontroller family, which supports ZigBee
applications and offers a wide selection of products with 16 Kbytes to 128 Kbytes of Flash program memory in 18- to
80-pin packages. Microchip's ZigBee stack is the only stack small enough to fit into a 16 Kbyte microcontroller,
enabling low-cost sensors. The stack is sized at 33.7 Kbytes for a coordinator and 14.4 Kbytes for reduced function
devices. Microchip’s PICDEM Z platform accelerates customer designs by providing hardware and a free ZigBee protocol
stack that can be easily integrated into wireless products.
Microchip offers more than 63 PIC18
8-bit microcontrollers that support the ZigBee stack and incorporate nanoWatt technology power-managed modes and
self-programmable Flash program memory -- key features for ZigBee applications, many of which are battery operated.
Typical ZigBee applications like sensors and controls can utilize all of Microchip's product lines including the
low-power analog portfolio and serial EEPROMs.
Microchip's ZigBee Stack is available today at no
cost on the Company's Web site. The PICDEM Z Demonstration Board is available today for $199 each.
