1.3 Description

The CC1350 device is a cost-effective, ultra-low-power, dual-band RF device from Texas Instruments™ that is part of the SimpleLink^™ microcontroller (MCU) platform. The platform consists of Wi-Fi®, Bluetooth® low energy, Sub-1 GHz, Ethernet, Zigbee®, Thread, and host MCUs. These devices all share a common, easy-to-use development environment with a single core software development kit (SDK) and a rich tool set. A one-time integration of the SimpleLink platform enables users to add any combination of devices from the portfolio into their design, allowing 100 percent code reuse when design requirements change. For more information, visit www.ti.com/simplelink.

With very low active RF and MCU current consumption, in addition to flexible low-power modes, the device provides excellent battery life and allows long-range operation on small coin-cell batteries and in energy harvesting applications.

The CC1350 is a device in the CC13xx and CC26xx family of cost-effective, ultra-low-power wireless MCUs capable of handling both Sub-1 GHz and 2.4-GHz RF frequencies. The CC1350 device combines a flexible, very low-power RF transceiver with a powerful 48-MHz Arm^® Cortex^®-M3 microcontroller in a platform supporting multiple physical layers and RF standards. A dedicated Radio Controller (Cortex^®-M0) handles low-level RF protocol commands that are stored in ROM or RAM, thus ensuring ultra-low power and flexibility to handle both Sub-1 GHz protocols and 2.4 GHz protocols (for example Bluetooth low energy). This enables the combination of a Sub-1 GHz communication solution that offers the best possible RF range together with a Bluetooth low energy smartphone connection that enables great user experience through a phone application. The Sub-1 GHz only device in this family is the CC1310.

The CC1350 device is a highly integrated, true single-chip solution incorporating a complete RF system and an on-chip DC/DC converter.

Sensors can be handled in a very low-power manner by a dedicated autonomous ultra-low-power MCU that can be configured to handle analog and digital sensors; thus the main MCU (Arm^® Cortex^®-M3) can maximize sleep time.

The power and clock management and radio systems of the CC1350 device require specific configuration and handling by software to operate correctly, which has been implemented in the TI-RTOS. TI recommends using this software framework for all application development on the device. The complete TI-RTOS and device drivers are offered free of charge in source code.
