Texas Instruments CC256x 蓝牙 4.0 控制器
Texas Instruments CC256x 蓝牙 4.0 控制器是一款基于 TI 第七代内核的完整的蓝牙4.0双模式 BR/EDR/LE HCI 解决方案’。 当与一个 MCU 器件耦合时，这个 HCI 器件可提供业界最佳的RF性能。TI’的电源管理硬件和软件算法大大节省了所有广泛使用的蓝牙BR/EDR/LE模式运行的能耗。借助于传输功率和接收敏感度，相对于其它只支持 BLE 的解决方案，这个解决方案提供大约 2 倍的业界最佳范围。TI 提供的一款无版权软件蓝牙堆栈被与 TI MSP430和ARM Cortex M3 以及 Cortex M4 MCU 集成在一起。目前支持的一些配置包括：串行端口配置 (SPP)、人机接口设备 (HID)、几个BLE 配置（根据支持的 MCU，这些配置会不同）
