2.1 BR/EDR Features
The CC256x device fully complies with the Bluetooth 4.0 specification up to the HCI level (for the family
members and technology supported, see Table 1-1):
• Up to seven active devices
• Scatternet: Up to 3 piconets simultaneously, 1 as master and 2 as slaves
• Up to two synchronous connection oriented (SCO) links on the same piconet
• Very fast AFH algorithm for asynchronous connection-oriented link (ACL) and extended SCO (eSCO)
link
• Supports typically 12-dBm TX power without an external power amplifier (PA), thus improving
Bluetooth link robustness
• Digital radio processor (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
• Flexible pulse-code modulation (PCM) and inter-IC sound (I2S) digital codec interface:
– Full flexibility of data format (linear, A-Law, μ-Law)
– Data width
– Data order
– Sampling
– Slot positioning
– Master and slave modes
– High clock rates up to 15 MHz for slave mode (or 4.096 MHz for master mode)
• Support for all voice air-coding
– Continuously variable slope delta (CVSD)
– A-Law
– μ-Law
– Transparent (uncoded)
• The CC2560B and CC2564B devices provide an assisted mode for the HFP1.6 (wide-band speech
[WBS]) profile or A2DP profile to reduce host processing and power.
2.2 LE Features
The device fully complies with the Bluetooth 4.0 specification up to the HCI level (for the family members
and technology supported, see Table 1-1):
• Supports all roles defined by the Bluetooth v4.0 specifications
• Solution optimized for proximity and sports use cases
• Supports up to 6 (CC2564) or 10 (CC2564B) simultaneous connections
• Multiple sniff instances that are tightly coupled to achieve minimum power consumption
• Independent buffering for LE, allowing large numbers of multiple connections without affecting BR/EDR
performance.
• Includes built-in coexistence and prioritization handling for BR/EDR and LE
NOTE
ANT and the assisted modes (HFP1.6 and A2DP) are not available when BLE is enabled.
