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, 2.4-GHz 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 48 MHz 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
The power and clock management and radio systems of the CC2640R2F wireless MCU require specific configuration 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 complete TI-RTOS and device drivers
are offered in source code free of charge from
Bluetooth low energy controller and host libraries are embedded in
ROM and run partly on an ARM® Cortex®-M0
processor. This architecture improves overall system performance and power consumption and frees up
significant amounts of flash memory for the application.
The Bluetooth stack is available free of charge from
