　　TI公司的CC2541是2.4GHz蓝牙低功耗系统级芯片（SoC），支持250kbps， 500kbps， 1Mbps和2Mbps数据速率，具有极好的连接预算，应用时不外接前端，输出功率可编程到0dBm， 1Mbps时的接收灵敏度为-94dBm，主要用在2.4GHz蓝牙低功耗系统，个人2.4GHz系统，人机接口如键盘，鼠标和遥控等，体育和休闲设备，手机附件和消费类电子。本文介绍了CC2541主要特性，方框图，应用电路图和CC2541评估模块主要特性，电路图和材料清单以及采用TPS62370的CC2541EM电源电路图和材料清单。
　　The CC2541 is a power-optimized true system-on-chip （SoC） solution for both low energy and proprietary 2.4-GHz applications. It enables robust network nodes to be built with low total bill-of-material costs. The CC2541 combines the excellent performance of a leading RF transceiver with an industry-standard enhanced 8051 MCU， in-system programmable flash memory， 8-KB RAM， and many other powerful supporting features and peripherals. The CC2541 is highly suited for systems where ultralow power consumption is required. This is specified by various operating modes. Short transition times between operating modes further enable low power consumption.
　　The CC2541 is pin-compatible with the CC2540 in the 6-mm × 6-mm QFN40 package， if the USB is not used on the CC2540 and the I2C/extra I/O is not used on the CC2541.

　　CC2541评估模块
　　The CC2541 Evaluation Module Kit contains two CC2541 Bluetooth low energy Evaluation Modules， which can be used either as standalone modules （requires a power source and a simple carrier board like the SoC Battery Board or connected to e.g. the SmartRF05EB Evaluation Boards （included in the CC2540DK） for full control from the PC.
　　The evaluation modules can be used as a reference board for prototyping and for verifying the performance of the CC2541 RF IC.
