Bangalore: Microchip Technology, a provider of microcontroller, analog and Flash-IP solutions, has announced its new MRF89XA transceiver. The new transceiver announced during the Embedded Systems Conference in Chicago is claimed to offer low receive current of 3mA for longer battery life in 868, 915 and 950 MHz Sub-GHz wireless networks.
The 868 MHz MRF89XAM8A and 915 MHz MRF89XAM9A transceiver modules accelerate design cycles by removing the complexity of designing RF circuitry and the cost of obtaining agency certification, according to Microchip. The Sub-GHz frequency bands are sometimes preferred by designers for a broad range of battery-powered wireless sensor networks and metering communications.
In addition to the low-power receive current for extending battery life, Microchip's MRF89XA transceiver and modules integrate a 12.5 dBm Power Amplifier for long transmission distances and a Low Noise Amplifier for -113 dBm enhanced receive sensitivity.
To ease communication and further prolong battery life, the MRF89XA combines an integrated packet handler with a 64-byte FIFO for transmit and receive buffering. "The combination of this transceiver with our nanoWatt XLP family of eXtreme Low Power PIC microcontrollers provides an industry-leading platform for Sub-GHz wireless networking," said Steve Caldwell, Director of Microchip's RF Products Division.
