Features & Applications

The SX1212-11SKA433 is a low cost single-chip transceiver operating in the frequency ranges from 300 MHz to 510 MHz. The SX1212-11SKA433 is optimized for very low power consumption (3 mA in receiver mode).

It incorporates a baseband modem with data rates up to 150 kb/s. Data handling features include a sixty-four byte 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. It complies with European (ETSI EN 300-220 V2.1.1) and North American (FCC part 15.247 and 15.249) regulatory standards.
