open-in-new Find other Sub-1 GHz products


The CC11x1-Q1 device family is designed for very low-power wireless applications. The circuits are mainly intended for the Industrial, Scientific and Medical (ISM) and Short Range Device (SRD) frequency bands at 315 MHz, 433 MHz, 868 MHz, and 915 MHz, but can easily be programmed for operation at other frequencies in the 310-MHz to 348-MHz, 420-MHz to 450-MHz, and 779-MHz to 928-MHz bands.

The devices integrate a highly configurable baseband modem. The modem supports various modulation formats and has a configurable data rate up to 250 kBaud. CC11x1-Q1 family 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 can be controlled via an SPI interface. In a typical system, the devices are used together with a microcontroller and a few additional passive components.
