STMicroelectronics S2-LPQTR RF Transceiver IC, 24-Pin QFN / 1637341

The S2-LP 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 and 920 MHz, but can also be programmed to operate at other additional frequencies in the 430-470 MHz, 860-940 MHz bands. The S2-LP supports different modulation schemes: 2(G)FSK, 4(G)FSK, OOK and ASK.Excellent receiver selectivity and blocking Programmable RF output power up to +16 dBm Programmable RX digital filter Programmable channel spacing Fast startup and frequency synthesizer settling time Automatic frequency offset compensation, AGC and symbol timing recovery Embedded timeout protocol engine Antenna diversity algorithm Fully integrated ultra-low power RC oscillator Wake-up driven by internal timer or external event Digital real time RSSI Flexible packet length with dynamic payload length
