The SX1211I084TRT is an ultra-low Power Integrated UHF Transceiver operating in the frequency ranges from 863 to 870, 902 to 928 and 950 to 960MHz. The SX1211 is optimized for very low power consumption (3mA in receiver mode). It incorporates a baseband modem with data rates up to 200kbps. Data handling features include a 64bytes FIFO, packet handling, automatic CRC generation and data whitening. Its highly integrated architecture allows for minimum external component count whilst maintaining design flexibility. All major RF communication parameters are programmable and most of them may be dynamically set.
