SPIRIT1 RF TRANSCEIVER
ST’s SPIRIT1 transceiver is intended for RF wireless-sensor node applications in the sub-1 GHz band, such as Automatic Meter Infrastructure, alarm and security systems, home and building automation, and industrial monitoring and control. It combines excellent receiver sensitivity with a very low current consumption. Additional embedded features include a “Listen-before-talk with”(CSMA/CA) engine, an AES-128-bit data encryption, error correction and detection, FIFO memory blocks, as well as a highly flexible and programmable data packet which contributes to further reducing the computational load of the host microcontroller and the overall system power consumption. SPIRIT1 is designed to operate within the ISM and SRD sub-1 GHz frequency bands namely at 169, 315, 433, 868, and 915 MHz. Several software stacks are available, such as the 6LoWPAN protocol stack enabling low-power devices to participate in the IoT, and the wireless M-Bus protocol stack (based on European standard 13757-4:2011.10) mainly addressing energy meter applications.
