Description
The CC1125 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, 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 CC1125 provides extensive hardware support for
packet handling, data buffering, burst transmissions, clear
channel assessment, link quality indication and Wake-On-
Radio. The CC1125 main operating parameters can be
controlled via an SPI interface. In a typical system, the
CC1125 will be used together with a microcontroller and
only few external passive components.
