Module Simplifies ZigBee Support

The ZigRay Wireless Data Transceiver module from Tecnova is a small-footprint pc board that incroporates a Freescale MC9S08GT60 microcontroller with an MC13192/3 ZigBee transciever. The module is available with or without a ZigBee protocol stack. The wireless data rate is 250 kbits/s, and the microcontroller interface is 19.2 kbits/s serial. Eight data lines and four 10-bit analog-to-digital converter connections from the microcontroller are available. Pricing for the transceiver starts at $50, or $35 in OEM quantities. The communications module costs $275. www.tecnova.com

ZigBee Transceiver Melds With MCU

Freescale's MC1320X family includes three pin-compatible standalone 2.4-GHz RF transceivers with an integrated Tx/Rx switch designed to mesh with with Freescale's HCS08, HC12, Coldfire, and DSC processors. Integrated versions will use Freescale's low-voltage, low-power HCS08 core with embedded flash memory and peripherals, such as 10-bit analog-to-digital converters, and low-voltage/brownout and keyboard interrupts. The chips will run Freescale's wireless Zstack. The stack initially will support proprietary point-to-point and simple ZigBee star networking. Pricing will start at $2.35. www.freescale.com
