NRF905 Datasheet

Single chip 433/868/915MHz Transceiver


NRF905 is a single chip radio transceiver for the 433/868/915MHz ISM band. The transceiver consists of a fully integrated frequency synthesizer, receiver chain with demodulator, a power amplifier, a crystal oscillator and, a modulator. The ShockBurst&trade; feature automatically handles preamble and CRC. You can easily configure the NRF905 through the SPI. Current consumption is very low, in transmit only 9mA at an output power of -10dBm, and in receive mode 12.5mA. Built-in power down modes makes power saving easily realizable. NRF905 Features &bull; True single chip GFSK transceiver in a small 32 pin package (32L QFN 5x5mm)&bull; ShockBurst&trade; mode for low power operation&bull; Power supply range 1.9 to 3.6 V&bull; Multi channel operation &ndash; ETSI/FCC Compatible&bull; Channel switching time <650&mu;s&bull; Extremely low cost Bill of Material (BOM)&bull; No external SAW filter&bull; Adjustable output power up to 10dBm&bull; Carrier detect for "listen before transmit" protocols&bull; Data Ready signal when a valid data packet is received or transmitted&bull; Address Match for detection of incoming packet&bull; Automatic retransmission of data packet&bull; Automatic CRC and preamble generation&bull; Low supply current (TX), typical 9mA @ -10dBm output power&bull; Low supply current (RX), typical 12.5mA NRF905 Applications &bull; Wireless data communication&bull; Alarm and security system&bull; Home automation&bull; Remote control&bull; Surveillance&bull; Automotive&bull; Telemetry&bull; Keyless entry&bull; Toys
