Ultra-low power dual band wireless MCU excellent battery lifetime

The CC1350, from Texas Instruments, is a member of the CC26xx and CC13xx family of cost-effective, ultra-low-power, 2.4GHz and Sub-1 GHz RF devices. Very low active RF and MCU current consumption, in addition to flexible low-power modes, provide excellent battery lifetime and allow long-range operation on small coin-cell batteries and in energy-harvesting applications. The device combines a flexible, very low-power RF transceiver with a powerful 48MHz ARM Cortex-M3 MCU 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-1GHz protocols and 2.4GHz 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-1GHz only device in this family is the CC1310. The device is a highly integrated, true single-chip solution incorporating a complete RF system and an on-chip DC-DC converter. The devices power and clock management and radio systems require specific configuration and handling by software to operate correctly, which has been implemented in the TI-RTOS.
