5.3 Functional Blocks
The TI Bluetooth HCI module architecture comprises a DRP™ and a point-to-multipoint baseband core.
The architecture is based on a single-processor ARM7TDMIE^® core. The module includes several on-chip
peripherals to enable easy communication with a host system and the Bluetooth BR/EDR/LE core.
5.4 Bluetooth BR/EDR Description
The CC2564MODx is Bluetooth 4.1 compliant up to the HCI level (for the technology supported, see
Table 5-1):
• 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 10-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 with external antenna
(CC2564MODN). The CC2564MODA includes the antenna on the module.
• 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
• 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
– CVSD
– A-Law
– μ-Law
– Transparent (uncoded)
5.5 Bluetooth LE Description
• Bluetooth 4.1 compliant
• Solution optimized for proximity and sports use cases
• 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 (HFP 1.6 and A2DP) are not available when BLE is enabled.
