ZMD announced the immediate availability of its second-generation ZMD44102 RF transceiver IC and starter kits. According to the company, the ZMD44102 is the industry's only commercially available sub-1GHz transceiver designed for ZigBee technology and applications.

Compliant to the IEEE 802.15.4 standard, the new transceiver IC operates in both the license-free North American band of 902MHz to 928MHz and in the European band of 868MHz to 870MHz. It features range performance of more than 250m at 0dBm output power and has ultra-low-power modes of operation, including a network maintenance power mode of less than 3?A.

The transceiver achieves data transmission rates up to 40kbps. An integrated thin-hardware media access controller at the physical layer of the radio reduces the number of external components and lowers installed system costs.

Target applications include wireless sensor networks, industrial controls, smart digital home and building automation systems, health monitor networks, hazardous sensor monitors, and automatic meter reading.

The available starter kit bundle, designated the ZMD44102SKB, includes the hardware, software and documentation necessary for designers to do a detailed product evaluation and begin applications development. The three-node bundle contains a graphical user interface and configuration tool that demonstrates the performance of the ZMD44102, controls its registers and establishes basic networking. ZMD's TSic temperature sensor is included and provides an immediate wireless sensor solution. The bundle also includes a development tool CD and debug adaptor for code compiling and downloading. A basic-edition Daintree sensor network analyzer allows the designer to capture and evaluate IEEE 802.15.4 frame packets.

Packaged in a lead-free QFN-48, the ZMD44102 RF transceiver is available at a unit price of $2.97 in quantities of 100,000 pieces. The ZMD44102SKB starter kit bundle is priced at $399. Meanwhile, a two-node starter kit without the sensor network analyzer and programming tools is available for $199.
