1.3 Description
The CC2564C device from Texas Instruments™ is a complete Bluetooth® BR/EDR, and low energy HCI
level solution, providing high performance and robust Bluetooth solution. Based on TI’s seventhgeneration
Bluetooth core, the CC2564C device provides a product-proven solution that is Bluetooth 5.1-
compliant, adding LE security and enhancing support for complex topologies (dual mode and link layer
topologies). This HCI device offers best-in-class RF performance with about twice the throughput of other
Bluetooth low-energy solutions, and includes a royalty-free software stack compatible with several host
MCUs and MPUs, for a complete Bluetooth solution. Furthermore, TI’s power-management hardware and
software algorithms provide significant power savings in all commonly used Bluetooth BR, EDR, and low
energy modes of operation.
The TI dual-mode Bluetooth stack software is certified and provided royalty free for MCUs and MPUs. The
iPod® (MFi) protocol is supported by add-on software packages. For more information, see TI Dual-Mode
Bluetooth Stack. Multiple profiles and sample applications, including the following, are supported:
Serial port profile (SPP)
Advanced audio distribution profile (A2DP)
Audio/video remote control profile (AVRCP)
Hands-free profile (HFP)
Human interface device (HID)
Generic attribute profile (GATT)
Several Bluetooth low energy profiles and services
