Microchip Technology Inc. has beefed up it RF products division wireless portfolio with the MRF49XA sub-GHz transceiver radio. The MRF49XA covers the 434-/868-/915MHz unlicensed ISM RF band, which is intended 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 the MRF49XA sub-GHz transceiver with any 8-, 16- or 32bit 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 MRF49XA transceiver radio is available on a PICtail/PICtail Plus daughter board for easy integration with the 8bit PIC18 Explorer and 16/32bit Explorer 16 modular MCU development boards. The 434MHz Daughter Board (part # AC164137-1, $39.99 for a two-pack) and 868-/915MHz daughter board (part # AC164137-2, $39.99 for a two-pack) are both available today.

Microchip's full suite of development tools further enables easy integration of the MRF49XA transceiver radio with more than 550 PIC MCUs. 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.

Pricing starts at $1.63 each in 10,000-unit quantities. 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.
