The CC2640R2F device is a wireless microcontroller (MCU) targeting Bluetooth® 4.2 and Bluetooth 5 lowenergyapplications.The device is a member of the SimpleLink™ ultra-low power CC26xx family of cost-effective, 2.4-GHz RFdevices. Very low active RF and MCU current and low-power mode current consumption provide excellentbattery lifetime and allow for operation on small coin cell batteries and in energy-harvesting applications.
The SimpleLink Bluetooth low energy CC2640R2F device contains a 32-bit ARM® Cortex®-M3 core thatruns at 48 MHz as the main processor and a rich peripheral feature set that includes a unique ultra-lowpower sensor controller. This sensor controller is ideal for interfacing external sensors and for collectinganalog and digital data autonomously while the rest of the system is in sleep mode. Thus, the CC2640R2Fdevice is great for a wide range of applications where long battery lifetime, small form factor, and ease ofuse is important.
The power and clock management and radio systems of the CC2640R2F wireless MCU require specificconfiguration 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 completeTI-RTOS and device drivers are offered in source code free of charge from www.ti.com.
Bluetooth low energy controller and host libraries are embedded in ROM and run partly on an ...
