Transceivers for Wi-Fi and ISM

7 July 2010 Telecoms, Datacoms, Wireless, IoT

Microchip has made available two new wireless connectivity solutions targeting both the certified IEEE802.11 (Wi-Fi) market and the sub-GHz ISM bands. The combination of next-generation transceiver solutions, development tools and software provides platforms for designers to wirelessly-enable a wide range of monitoring and control products.

The agency-certified MRF24WB0MA/MB embedded Wi-Fi transceiver module’s firmware has an easy-to-use API driver interface to Microchip’s free TCP/IP protocol stack and 8-, 16- or 32-bit PIC microcontrollers. The free TCP/IP stack has been improved, and offers free EZconfig and ZeroConfig utility protocols, to simplify commissioning and configuring of Wi-Fi networks.

The new MRF89XA transceiver offers low receive current of 3 mA, a 12,5 dBm power amplifier for long transmission distances and a low noise amplifier for

-113 dBm receive sensitivity. An integrated packet handler with a 64 Byte FIFO for transmit and receive buffering further extends battery life in 868, 915 and 950 MHz sub-GHz wireless networks. The 868 MHz MRF89XAM8A and 915 MHz MRF89XAM9A transceiver modules remove the complexity of designing RF circuitry and the cost of obtaining agency certification.
