The recommended operating voltage range for the CC2650F128RHBR is 1.8V to 3.8V.
To configure the CC2650F128RHBR for optimal power consumption, use the Power Manager (PM) module to control the power modes, and adjust the clock frequency and voltage scaling according to your application's requirements.
The maximum data transfer rate of the CC2650F128RHBR's UART is 4 Mbps.
Yes, the CC2650F128RHBR can be used with an external antenna. However, you need to ensure that the antenna is properly matched to the device's RF output impedance and that the antenna's radiation pattern meets your application's requirements.
To implement secure boot and firmware updates on the CC2650F128RHBR, use the device's built-in security features, such as the Secure Boot Loader (SBL) and the Firmware Update (FU) module, in conjunction with cryptographic algorithms like AES and SHA.
