Next-generation 2mA Low-power Transceiver Supports Industrial Operating Temperatures and China Unlicensed Frequency Bands

ALISO VIEJO, Calif., May 7, 2013 — (PRNewswire) —  Microsemi Corporation (Nasdaq: MSCC), a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, today announced the ZL70251 ultra low-power (ULP) radio frequency (RF) transceiver with an extended temperature operating range of -40 degrees centigrade (C) to 85 degrees C 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 megahertz (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.

"Extending the temperature range of our industry-leading low-power consumption radio allows us to address increasing demand for M2M low power nodes used in automation and industrial control applications," said Francois Pelletier, product marketing director of Microsemi's ULP product group. "Increasing our frequency band parameters also enable to broaden our geographic footprint and capitalize on growing market opportunities in China."

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 millimeter (mm) x 2mm chip scale package (CSP) and requires only two external components, which makes it ideal 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. For more information, or to obtain a sample, email Email Contact or contact your local distributor or Microsemi sales representative.
