Flurry of announcements seen heading into ZigBee open house

Freescale's ZigBee platform is being used by Panasonic Electronic Devices Corp. to provide a general purpose ZigBee-compliant module, named PAN802154HAR that is available via Arrow Electronics.

Freescale touts its power-saving modes as a differentiator for its silicon solution and platform with the MC13193 and HCs08 microcontroller. The popular Figure 8's Z-Stack is included in the platform as well as printed antennae and multiple peripheral ports. The Panasonic module supports ZigBee or non-ZigBee/proprietary 802.15.4 operation. Sensitivity is high at -92dBm, and will only get better.

Texas Instruments has been very quiet and was "not talking" last spring. However, that is changing with the recent Ember announcement where Ember jointly developed a low-power ZigBee platform using TI's 16-bit MSP430F162 microcontroller, Ember's EM2420 transceiver and Ember's EmberZNet software. Ember's resulting development kits start at $4,995.

Chipcon announced its second-generation SoC, the CC2430 that integrates radio, PHY, MAC and 8051 MCU. This also comes with the Chipcon Figure 8 Z-Stack. Aside from RAM on chip, three versions are available with different densities of Flash, ranging from 32K to 128K bytes, with pricing from $3.30 to $3.90 in high volumes when production mode begins. Production development kits will start shipping in November, with mass production chip mode following.

Integration Associates has teamed up with OKI as well as with Renesas for a ZigBee platform. Oki's ML7065 LSI chip includes the 802.15.4 radio, PHY and MAC, and uses a 0.22?m CMOS process. The MAC incorporation enables the use of a lesser cost MCU. The resulting development kit is $1,500 and includes multiple transceivers. The kit includes the Oki chip, Integration's CompXs ZigBee-certified stack, and Renesas' H8 microcontroller. This platform has received ZigBee certification. Integration expects to see modules by the end of the year. Sampling is occurring now, with production slated for December. Integration's other announcement regards Integration's EZRadio combined with Renesas' H8/3687F microcontroller, and the Integration CompXs stack.

It's a good sign to see more development kits ZigBee certified, and chips getting into production mode. Manufacturers wanting to develop and get products onto the market have been pulling chip suppliers more than the suppliers have been pushing their customers. At least that's better than the other way around.
