MC1322x Zigbee platform from Freescale

Freescale Semiconductor has introduced a Zigbee-based, single-chip platform that promises the industry's lowest power consumption and highest performance. The MC1322x platform is engineered to support battery life of up to 20 years, doubling the expectations for current Zigbee solutions, the company said.

PiP solution
The MC1322x is available in a Platform in Package (PiP) solution that integrates the essential components of a Zigbee application within a single package, thereby reducing component count and system cost. The platform contains a 32bit MCU, a fully compliant IEEE 802.15.4 transceiver, balun and RF matching componentsall integrated into a small-footprint LGA package that virtually eliminates the need for external RF components. The platform solution also features a TurboLink technology mode, engineered to increase data rates by up to 2Mbps between nodes.

"We designed our Zigbee Platform in Package from the ground up to deliver the lowest power consumption and highest performance within a highly integrated package," said Brett Black, manager of Freescale's wireless connectivity operation. "The MC1322x is designed for a new class of wireless applications that require faster streaming of audio and data files across an IEEE 802.15.4 or Zigbee network."

TurboLink tech
Zigbee technology currently targets industrial, commercial and medical applications, such as energy management and asset tracking. Freescale's proprietary TurboLink technology mode boosts the data rate up to 2Mbps, providing a platform for diverse applications such as voice, wireless headsets and compressed audio, as well as large data transfers. For healthcare-related applications, such as patient monitoring systems, TurboLink technology also enables real-time data collection from sensors on the body. That data then can be sent via a Zigbee network to a central location for monitoring.

MC1322x devices will switch automatically between the IEEE 802.15.4 protocol and TurboLink technology packets, allowing the developer to take advantage of the high-speed capabilities, while simultaneously controlling and monitoring a Zigbee mesh network.

The MC1322x platform was designed to support battery-powered applications. Optimized for Li-ion or NiCad batteries, the MC1322x is designed to support batteries as small as coin cells or use standard alkaline batteries that can provide up to 20 years of system life.

All RF tuning components and balun are contained within the MC1322x package, requiring only an antenna and crystal to be connected for operation. Freescale plans to add RAM- and flash-based PiP solutions to the MC1322x family.

Freescale's BeeKitTM Wireless Connectivity Toolkit provides an easy-to-use configuration tool for creating networks ranging from simple point-to-point to full Zigbee mesh networks.

Availability, pricing
Freescale plans to offer MC1322x device samples to key OEM customers in May 2007. General market sampling is planned for Dec. 2007. The company plans to offer the MC1322x device in two package options: a 9.5-by-9.5mm LGA and a 7-by-7mm QFN. The devices are also planned to be available in standard mode or TurboLink mode. Suggested resale pricing for the standard-mode devices in LGA packaging is $5.50 in 10,000 quantities.
