The CC2640R2F device is a wireless microcontroller (MCU) targeting Bluetooth 4.2 and Bluetooth 5 low-energy applications. The device is a member of the SimpleLink ultra-low power CC26xx family of cost-effective, 2.4GHz RF devices. Very low active RF and MCU current and low-power mode current consumption provide excellent battery 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 that runs at 48MHz as the main processor and a rich peripheral feature set that includes a unique ultra-low power sensor controller.
This sensor controller is ideal for interfacing external sensors and for collecting analog and digital data autonomously while the rest of the system is in sleep mode. Thus, the CC2640R2F device is great for a wide range of applications where long battery lifetime, small form factor, and ease of use is important.
