CC1101 is a low-cost sub-1 GHz transceiver designed for very low-power wireless applications. It operates in ISM/SRD bands (315/433/868/915 MHz) and can be programmed for 300-348 MHz, 387-464 MHz, and 779-928 MHz bands. Features include a highly configurable baseband modem supporting modulations (2-FSK, 4-FSK, GFSK, MSK, OOK, ASK) with data rates up to 600 kbps. It provides hardware support for packet handling, data buffering, burst transmissions, clear channel assessment, link quality indication, and wake-on-radio. The device includes 64-byte TX/RX FIFOs, SPI interface for control, and integrates frequency synthesizer without external filters. It offers high sensitivity, low power consumption, and is suitable for compliance with EN 300 220, FCC CFR Part 15, and Wireless MBUS standards.
