The ccRF 3 Click is designed to run on a 3.3V power supply. It communicates with the target microcontroller over SPI interface, with additional functionality provided by the following pins on the mikroBUSline: AN, RST, CS, PWM, INT.
Note: the Click requires an external N.FL. antenna .
CC1120 RF transceiver features
The CC1120 device is a fully integrated single-chip radio transceiver designed for high performance at very low-power and low-voltage operation.
The device is mainly intended for Industrial, Scientific, and Medical (ISM) applications and Short Range Device (SRD).
The CC1120 device 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 of the CC1120 device can be controlled through an SPI interface.
Wake-On-Radio or eWOR y enables CC1120 to periodically wake up from SLEEP and listen for incoming packets without MCU interaction.
When the CC1120 device enters RX mode, it listens and then returns to sleep if a valid RF packet is not received. The sleep interval and duty cycle can be configured to make a trade-off between network latency and power consumption. Incoming messages are time-stamped to simplify timer resynchronization. The eWOR timer runs off an ultra-low-power 32-kHz RC oscillator.
In IDLE mode the CC1120 uses 1.3mA, while in power down with retention mode the consumption goes to 0.12.
