The CC1101 is a low-cost sub-1GHz transceiver designed for very low-power wireless applications.
The CC1101 transceiver is designed for ultra‑low‑power wireless applications in the 315/433/868/915 MHz ISM/SRD bands, such as alarm systems, industrial monitoring, sensor networks and home automation. It integrates a configurable baseband modem with SPI control, allowing easy integration with microcontrollers.
Key features include high sensitivity, programmable output power up to +10 dBm, a wide selectable frequency range, low current consumption (14.7 mA in RX, 400 nA in sleep), and extensive packet‑handling hardware. The device is offered in a compact QLP 4×4 mm, 20‑pin package and complies with EN 300 220 and FCC Part 15 regulations.
