Microsemi Corp. has started to sample an ultra-low-power (ULP) RF transceiver dubbed ZL70251 with an extended temperature operating range of -40ºC to 85ºC for short-range wireless sensor products used in industrial applications.
In addition, the next-generation transceiver now can be used in unlicensed frequency bands ranging from 779-965 MHz, which broadens the scope of operation from the previously supported North American (915 MHz) and Europe (868 MHz) bands to include China's 779-787 MHz radio frequency spectrum.
The ZL70251 is fully functional over the industrial temperature range, while still delivering the industry's lowest peak power at 2mA in both transmit and receive mode. This performance enables extremely low-power wireless nodes to operate in harsh environments. It is offered in a compact 3 mm x 2mm chip scale package (CSP) and requires only two external components, which makes it well-suited for products with space constraints.
A suite of ZL70251 product development support tools are available, including an application development kit (ADK), a low-power wireless communication software code starter for point-to-point connections and wireless sensor reference designs based on coin cell batteries.
The new device is sampling now and will reach full production status in July 2013.
