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:
In 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.
