Abstract: This application note presents an overview of the operational characteristics of accurate I²C real-time clocks (RTCs),including the DS3231, DS3231M, and DS3232. It focuses on general application guidelines that facilitate use of device resources forpower management, I²C communication circuit configurations, and I²C characteristics relative to device power-up sequences andinitializations. Additional discussions on decoupling are provided to support developing strategies for mitigating power-supply pushingof device frequency.

The LTC®3562 quad output step-down regulator is designedfor multicore handheld microprocessor applications thatoperate from a single Li-Ion battery. Its four monolithic, higheffi ciency buck regulators support Intel’s mobile CPU P-Stateand C-State energy saving operating modes. The outputvoltages are independently controllable via I2C, and eachoutput can be independently started and shut down. Designerscan choose from power saving pulse-skipping mode orBurst Mode® operation, or select low noise LDO mode. Thespace-saving LTC3562 is available in a 3mm × 3mm QFNpackage and requires few external components.

The LTC®3569 is a compact power solution for handhelddevices. Its tiny 3mm × 3mm QFN package includesthree buck regulators with individually programmableoutput voltages. One regulator supports load currentsup to 1200mA, while the other two support currents to600mA. Two regulators can be paralleled for increasedload capability. Each current-mode regulator is internallycompensated with excellent load and line regulation. Acomplete 2- or 3-output solution requires a minimumof external passive components.

Avalanche photo diode (APD) receiver modules arewidely used in fi ber optic communication systems. AnAPD module contains the APD and a signal conditioningamplifi er, but is not completely self contained. It stillrequires signifi cant support circuitry including a highvoltage, low noise power supply and a precision currentmonitor to indicate the signal strength. The challenge issqueezing this support circuitry into applications withlimited board space. The LT®3482 addresses this challengeby integrating a monolithic DC/DC step-up converter andan accurate current monitor. The LT3482 can supportup to a 90V APD bias voltage, and the current monitorprovides better than 10% accuracy over four decades ofdynamic range (250nA to 2.5mA).

Keil C51是美国Keil Software公司出品的51系列兼容单片机C语言软件开发系统，与汇编相比，C语言在功能上、结构性、可读性、可维护性上有明显的优势，因而易学易用。Keil提供了包括C编译器、宏汇编、连接器、库管理和一个功能强大的仿真调试器等在内的完整开发方案，通过一个集成开发环境（uVision）将这些部分组合在一起。运行Keil软件需要WIN98、NT、WIN2000、WINXP等操作系统。如果你使用C语言编程，那么Keil几乎就是你的不二之选，即使不使用C语言而仅用汇编语言编程，其方便易用的集成环境、强大的软件仿真调试工具也会令你事半功倍。 解压缩以后安装，步骤如下： 1.打开up51v706a.txt(本文件)记下安装序列号。进入setup目录点击setup.exe进行安装； 2.选择Install support....全新安装，以前没有安装过或者放弃以前的序列号安装; 选择Update Current Installation升级安装，将可以保持原来的序列号，不必再次输入 3.选择Full安装，Next->Yes(接受版权信息)->选择安装目录->Next->输入序列号、姓名、公司 等，除了序列号以外，都随意，可以如实输入你的姓名等。->next-> ....直到安装完成。 注意： 1.每次安装都必须进行这几步，每次都需要重新写入AddOn标识； 2.假如安装过程中存在病毒防火墙，可能会产生xcopy错误使安装失败，此时请先 关闭病毒防火墙，然后再安装; 3.安装前必须退出正在运行的Keil软件，否则也会产生xcopy错误使安装失败； 4.安装过程中可能会出现安装Secrity Key错误，点击确定即可。 这组安装码可以使用keil C51软件到2033年12月底，够用了吧。 Ident = Y1DZKM (这个号码已经输入在addon目录下的文件中，你不必理会了) SN = K1DZP-5IUSH-A01UE *************************************** 0xfd汉字补丁已经预先处理。安装以后可以打开工程\keil\c51\examples\0xfd\ee.uv2检验
