CC1101 Description
CC1101 is a low-cost sub-1 GHz 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 915 MHz, but can easily be programmed for operation at other frequencies in the 300-348 MHz,387-464 MHz and 779-928 MHz 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 600 kbps.
CC1101 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 64- byte transmit/receive FIFOs of CC1101 can be controlled via an SPI interface. In a typical system, the CC1101 will be used together with a microcontroller and a few additional passive components.
The CC1190 850-950 MHz range extender [21] can be used with CC1101 in long range applications for improved sensitivity and higher output power.
