TI CC1125RHBR

CC1125 is a fully integrated single-chip RF transceiver designed for high performance with ultra-low power consumption and low-voltage operation in cost-effective wireless systems. All filters are integrated, eliminating the need for expensive external SAW and IF filters. The device is primarily intended for ISM and SRD 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 transmission, clear channel assessment, link quality indication, and wake-on-radio. The primary operating parameters of the CC1125 are configurable via the SPI interface. In a typical system, the CC1125 is used together with a microcontroller and a minimal number of external passive components.
