6.5 Bluetooth^® BR and EDR Features
The CC2564C device complies with the Bluetooth 4.2 specification up to the HCI layer (for family
members and technology supported, see Table 3-1):
• Up to seven active devices
• Scatternet: Up to three piconets simultaneously, one as master and two as slaves
• Up to two SCO links on the same piconet
• Very fast AFH algorithm for asynchronous connection-oriented link (ACL) and eSCO link
• Supports typical 12-dBm TX power without an external power amplifier (PA), thus improving Bluetooth
link robustness
• DRP single-ended 50-Ω I/O for easy RF interfacing
• Internal temperature detection and compensation to ensure minimal variation in RF performance over
temperature
• Includes a 128-bit hardware encryption accelerator as defined by the Bluetooth specifications
