The maximum transmission power of the CC2540F256RHAT is +4 dBm.
Frequency hopping can be implemented using the CC2540F256RHAT's built-in frequency synthesizer and the TI-provided software development kit (SDK). The SDK provides examples and documentation on how to implement frequency hopping.
Yes, the CC2540F256RHAT can be used with an external antenna. However, the antenna must be designed and matched to the CC2540F256RHAT's impedance to ensure optimal performance.
The maximum data transfer rate of the CC2540F256RHAT is 2 Mbps.
The CC2540F256RHAT has built-in AES encryption and decryption capabilities. The TI-provided SDK provides examples and documentation on how to implement encryption and decryption using the CC2540F256RHAT.
