The CC1101RGPR is a low-power Sub-1GHz RF Transceiver designed for very low-power wireless applications. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands at 315, 433, 868 and 915MHz, but can easily be programmed for operation at other frequencies in the 300 to 348MHz, 387 to 464MHz and 779 to 928MHz bands. The RF transceiver is integrated with a highly configurable baseband modem. The modem supports various modulation formats and has a configurable data rate up to 600kbps. CC1101RGPR provides extensive hardware support for packet handling, data buffering, burst transmissions, clear channel assessment, link quality indication and wake-on-radio. The main operating parameters and the 64byte transmit receive FIFOs of CC1101RGPR can be controlled via an SPI interface. In a typical system, the transceiver will be used together with a microcontroller and a few additional passive components.
