Freescale Semiconductor is now sampling the next-generation MC13224 device in its single-chip IEEE 802.15.4/ZigBee Platform-in-Package. This family is based on IEEE® 802.15.4 technology, optimized for low cost, low-power, real-time remote monitoring and control.
The integrated chip contains a 32-bit ARM7 microcontroller and is designed for a range of wireless applications, including energy management, commercial building automation, industrial control and monitoring and home entertainment control. The family supports existing protocols, such as SMAC, IEEE 802.15.4 MAC, ZigBee stack and Synkro network protocol stack, with the ability to support the WirelessHART specification, ISA100 and 6LoWPAN.
Freescale has integrated the essential components of an IEEE 802.15.4 based application within a single package, requiring designers to add only an antenna and crystal.
ZigBee is a low-power, low cost wireless communications technology, with integrated mesh networking, for sensor networks. ZigBee uses the PHY and MAC layers defined by IEEE 802.15.4, a short-distance wireless communication standard for 2.4 GHz band. ZigBee comprises the ZigBee platform specifications and ZigBee profiles defined by the ZigBee Alliance.
The Read Write Web has more on The Coming World of Mobile Sensors. Bob iannucci, Nokia’s chief technology officer expects mobile sensors in cell phones that can detect location and movement, barometric pressure and the weather around us, even our own personal health. In the near future, near-field communication, indoor positioning, and environmental analysis could be added.
