MCP73831 是一款高级线性充电管理控制器，它适用于 空间小而对成本敏感的应用场合。MCP73831 提供 8 引 脚2 mm x 3 mm DFN 和5 引脚SOT23 两种封装形式。 由于体积小且外接元件少，MCP73831 非常适用于便携 式设备。MCP73831 也可用于USB 充电设备，它符合 主流USB 总线电源的所有规范。 MCP73831 采用恒流/ 恒压充电算法，并提供预充选项 和充电结束控制选项。恒压充电调节有四个选择： 4.20V、4.35V、 4.40V 和4.50V，这可以适应最新涌现 出来的电池充电要求。恒流充电电流由一个外部电阻设 定。在高功率或高温的外界环境下， MCP73831 将根据 管芯温度对充电电流大小进行限制。热调节功能对充电 周期进行优化，并维持器件的可靠性。-err

USB调试助手 USBDEBUG是一款操作及其简单的USB调试工具软件。它能够快速准确的对USB设备进行数据的读写操作，可以实时监测从USB设备发来的数据。（目前只支持调试Philips公司的PDIUSBD12和ISP1581) -USB debugging assistant USBDEBUG is a simple USB operation and the debug tools. It can fast and accurate data on the USB device to read and write operations can be real-time monitoring from a USB device sent data. (Currently only supports debugging Philips company" s PDIUSBD12 and ISP1581)

usb接口控制器可以实时读取外界环境的当前温度，且当温度超过某一阈值或低于某一阈值时发出报警-usb interface controller can immediately read the current external environment temperature, and when the temperature exceeds a certain threshold value or below a certain threshold value warning issued

mp3设计程序资料，采用c语言编写。 README file for yampp-3 source code 2001-05-27 This is the current state of the yampp-3 source code, 2001-05-27. This code is intended to run on Rev. B of the yampp-3 PCB, but can ofcourse be used on compatible systems as well. It still uses the "old" song selection system as the yampp-2. However, the disk handling routines has improved a lot and the obviosly, the new VS1001 handling has been put in. The codesize is almost at it s maximum at 1F40 bytes. A .ROM file is included if you don t have the compiler set up. For now, the documentation is in the code- mp3 programming cook book in C.
