The SX1231 programmable RF transceiver features a 135-dBm link budget that is 10 dB more than competing devices. Features include a receive current of 16 mA and a transmit current of 33 mA. The frequency range is 290 to 1,020 MHz, which includes the 433-, 868-, and 915-MHz license-free ISM frequency bands.
The device features an integrated packet engine that offloads RF packetization from a microcontroller. The packet engine provides CRC error checking, AES-128 encryption and a 66-byte FIFO. The output power of the SX1231 is programmable in 1-dB steps from –18 to 17 dBm. Housed in a 24-pin QFN package, the transceiver operates with GFSK, MSK, FSK, OOK, ASK modulations types up to 300 kbit/s with constant RF performance over the 1.8 to 3.7-V supply range.
