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.
