Texas Instruments CC2564C Dual-Mode BLUETOOTH® Controller

Texas Instruments CC2564C Dual-Mode BLUETOOTH® Controller is a complete Bluetooth BR, EDR, and low energy HCI solution that reduces design effort and enables fast time to market. Based on TI's seventh-generation Bluetooth core, the CC2564C device provides a product-proven solution that is Bluetooth 4.2 compliant. When coupled with a microcontroller unit (MCU), this HCI device offers best-in-class RF performance with about twice the range of other Bluetooth low-energy solutions. 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.
