描述 Description

The TI CC256x device is a complete Bluetooth BR/EDR/LE HCI solution that reduces design effort and enables fast time to market. Based on TI?s seventh-generation Bluetooth core, the CC256x device provides a product-proven solution that is Bluetooth 4.1 compliant. When coupled with a microcontroller unit (MCU), this HCI device offers best-in-class RF performance with a range of about 2X compared to other Bluetooth LE-only solutions. Furthermore, TI?s power-management hardware and software algorithms provide significant power savings in all commonly used Bluetooth BR/EDR/LE modes of operation.

The TI Dual-Mode Bluetooth Stack software is certified and provided royalty free for TI?s MSP430 and ARM Cortex-M3 and Cortex-M4 MCUs. Other MPUs can be supported through TI?s third party. iPod? (MFi) protocol is supported by add-on software packages. For more information, see TI Dual-Mode Bluetooth Stack. Some of the profiles supported include the following:

Serial port profile (SPP) Advanced audio distribution profile (A2DP) Audio/video remote control profile (AVRCP) Handsfree profile (HFP) Human interface device (HID) Generic attribute profile (GATT)Several Bluetooth LE profiles and servicesIn addition to software, this solution consists of multiple reference designs with a low BOM cost, including a new Bluetooth audio sink reference design for customers to create a variety of applications for low-end, low-power audio solutions.
