TI公司的CC1350是双频段(2.4GHz和<1GHz)超低功耗无线MCU,具有非常低功耗的RF收发器,集成了功能强大的48MHz的-MHz Cortex-M3 MCU和片上DC/DC转换器,支持多种物理层和RF标准,是完整的单片解决方案.主要用在• 315-, 433-, 470-, 500-, 779-, 868-, 915-,920-MHz 和2.4-GHz ISM 以及SRD系统,低功耗无线系统,家庭和建筑物自动化,无线告警和安全系统,工业监视和控制等.本文介绍了CC1350主要特性,框图以及差分参考设计,Simplelink CC1350 LaunchPad蓝牙板主要特性,电路图,材料清单和PCB元件布局图l。

The CC1350 is a member of the CC26xx and CC13xx family of cost-effective, ultra-low-power, 2.4 GHzand Sub-1 GHz RF devices. Very low active RF and microcontroller (MCU) current consumption, inaddition to flexible low-power modes, provide excellent battery lifetime and allow long range operation onsmall coin-cell batteries and in energy-harvesting applications.

The CC1350 is the first device in the CC13xx and CC26xx family of cost-effective,ultra-low-powerwireless MCUs capable of handling both Sub-1 GHz and 2.4 GHz RF frequencies. The CC1350 devicecombines a flexible, very low-power RF transceiver with a powerful 48-MHz Cortex-M3 microcontroller in aplatform 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 powerand 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 bestpossible RF range together with a Bluetooth low energy smartphone connection that enables great userexperience 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 systemand an on-chip DC-DC converter.Sensors can be handled in a very low-power manner by a dedicated autonomous ultra-low-power MCUthat can be configured to handle analog and digital sensors; thus the main MCU (Cortex-M3) canmaximize sleep time.

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