Overview

The CC1125 is a fully integrated single-chip radio transceiver designed for ultra-low-power and narrowband wireless applications. It supports multiple modulation formats and operates across several sub-GHz frequency bands including 164-192 MHz, 274-320 MHz, 410-480 MHz, and 820-960 MHz. This device is optimized for performance in systems targeting compliance with ETSI EN 300 220 and FCC Part 15 and 90 regulations.

Why Choose This Part

The CC1125 offers industry-leading sensitivity of -129 dBm and high blocking performance to ensure reliable links in the presence of interferers. It features WaveMatch technology for improved sync detect and built-in coding gain support to maximize range without increasing transmit power.

Applications

Narrowband Wireless Systems
Ideal for 12.5 kHz and 25 kHz channel spacing systems requiring high selectivity and sensitivity.
Smart Metering (AMR/AMI)
Reliable long-range communication for utility meters with robust interference rejection.
Industrial Monitoring
Secure wireless sensor networks in harsh RF environments using clear channel assessment and auto-acknowledge features.
Wireless Alarm and Security
Low-power security sensors benefiting from eWOR functionality for extended battery life during polling.

Getting Started

Engineers should start with the CC1125DK Development Kit and use TI SmartRF Studio to evaluate RF performance and register configurations. The device is interfaced via a standard 4-wire SPI bus, and software development is supported by TI's protocol stacks or custom packet handling using the 128-byte RX/TX FIFOs.
