TI CC26XX chip

The CC26XX is a family of cost-effective, ultra-low power, 2.4 GHz RF devices. Extremely low active RF, MCU current, low power modes provide excellent battery life. And allow operation with small button batteries and energy harvesting applications. The low-power Bluetooth controller is embedded in ROM and runs partially on the ARM Cortex-M0 processor. This architecture improves overall system performance and power consumption and frees up flash memory for applications.
