ST’s Spirit1 is a high-performance, low-power wireless transceiver for automatic meter infrastructure and other wireless sensor node applications, including alarm and security systems, home and building automation, and industrial monitoring and control. ST's SPIRIT1 transceiver combines high receiver sensitivity with low current consumption. Replacing traditional  electromechanical meters, ‘smart’ electronic meters bring many advantages for utility providers and consumers such as full remote control, power peak and consumption analysis, anti-tampering mechanisms, fault alert, and time-variable tariffs. ST's SPIRIT1 transceiver handles the communication between smart meters in households and businesses and the neighborhood data concentrator, which relays the information to the utility provider control center. By enabling short-distance transmissions in frequency ranges below 1 GHz, SPIRIT1 ensures proper wireless signal propagation through concrete walls and building structures. SPIRIT1 delivers a competitive advantage of low current consumption, enabling SPIRIT1-equipped applications to operate for up to twice the time of other solutions. SPIRIT1 boasts a receiver sensitivity of -120dBm, and allows the designer to lower the output power of the transmitter, decreasing the overall current consumption while maintaining a robust communication channel. The transceiver supports advanced technologies like frequency hopping, auto-acknowledgment, and antenna diversity to provide error-free data transmission in harsh-environmental or challenging-logistical conditions. Additional embedded features include 128-bit data encryption, error correction and detection, FIFO memory blocks, as well as highly flexible and programmable data packet management, reducing the computation load on the host microcontroller.
