Microchip Offers Sub-GHz Transceiver Radios

June 10, 2009

The MRF49XA covers the 434/868/915-MHz ISM Band, is well suited for low–data rate, low-power embedded wireless applications, and provides easy integration with PIC microcontrollers.

CHANDLER, AZ -- Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, announced from the Sensors Expo in Chicago the expansion of its RF Products Division wireless portfolio with the new MRF49XA sub-GHz transceiver radio. The MRF49XA covers the 434/868/915 MHz unlicensed Industrial, Scientific and Medical (ISM) Radio Frequency (RF) band, which is ideal for low–data rate, low-power embedded wireless applications. By retaining compatibility with its existing suite of development tools, Microchip makes it easy to integrate this new sub-GHz transceiver with any 8-, 16- or 32-bit PIC microcontroller, enabling cost-effective designs for a wide range of, bi-directional, short-range wireless applications, such as remote controls, remote meter reading, and home security/alarms.

"The new MRF49XA transceiver is a great addition to our current rfPIC family of sub-GHz solutions, and expands our overall wireless portfolio beyond 2.4 GHz IEEE 802.15.4/ZigBee products," said Steve Caldwell, Director of Microchip's RF Products Division.

Development Tools
The MRF49XA transceiver radio is available on a PICtail™/PICtail Plus daughter board for easy integration with the 8-bit PIC18 Explorer and 16/32-bit Explorer 16 modular microcontroller development boards. The 434 MHz Daughter Board (part # AC164137-1, $39.99 for a two-pack) and 868/915 MHz Daughter Board (part # AC164137-2, $39.99 for a two-pack) are both available today at microchipDIRECT.

Microchips full suite of world-class development tools further enables easy integration of the MRF49XA transceiver radio with more than 550 PIC® microcontrollers. Available tools include the free MPLAB® IDE integrated development environment, the MPLAB REAL ICE™ emulation system, the MPLAB ICD 3 in-circuit debugger, the PICkit™ 3 low-cost debugger/programmer and Microchip's free C compilers.

Availability and Pricing
Samples are available now in 16-pin TSSOP packaging, and the MRF49XA Sub-GHz transceiver radio is expected to be available for volume production next month. Pricing starts at $1.63 each, in 10,000-unit quantities.
