1.3 Description
The CC1120 device is a fully integrated single-chip radio transceiver designed for high performance at
very low-power and low-voltage operation in cost-effective wireless systems. All filters are integrated, thus
removing the need for costly external SAW and IF filters. The device is mainly intended for the ISM
(Industrial, Scientific, and Medical) and SRD (Short Range Device) frequency bands at 164–192 MHz,
274–320 MHz, 410–480 MHz, and 820–960 MHz.
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. In a typical system, the
CC1120 device will be used together with a microcontroller and only a few external passive components.
Figure 1-1 shows pin names and locations for the CC1120 device.
