STMicroelectronics S2-LPS
The S2-LPS is a high performance ultra-low power RF transceiver, intended for RF wireless applications in the sub-1 GHz band. It is designed to operate in both the license-free ISM and SRD frequency bands at 433, 868 MHz, but can also be programmed to operate at other additional frequencies in the 413-479 MHz, 826-958 MHz bands. The S2-LPS supports different modulation schemes: 2(G)FSK, OOK and ASK.FEATURES
