高精度I2C實時時鐘的設計

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.

DN442 I2C可控降壓緊湊型同步DC/DC穩壓器

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.

三降壓穩壓器功能的1-Wire動態可編程輸出電壓

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.

GPON系統的APD偏置解決方案

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).

keil7.06完全破解版_免費下載

Keil C51是美國Keil Software公司出品的51系列兼容單片機C語言軟件開發系統，與匯編相比，C語言在功能上、結構性、可讀性、可維護性上有明顯的優勢，因而易學易用。Keil提供了包括C編譯器、宏匯編、連接器、庫管理和一個功能強大的仿真調試器等在內的完整開發方案，通過一個集成開發環境（uVision）將這些部分組合在一起。運行Keil軟件需要WIN98、NT、WIN2000、WINXP等操作系統。如果你使用C語言編程，那么Keil幾乎就是你的不二之選，即使不使用C語言而僅用匯編語言編程，其方便易用的集成環境、強大的軟件仿真調試工具也會令你事半功倍。解壓縮以后安裝，步驟如下： 1.打開up51v706a.txt(本文件)記下安裝序列號。進入setup目錄點擊setup.exe進行安裝； 2.選擇Install Support....全新安裝，以前沒有安裝過或者放棄以前的序列號安裝; 選擇Update Current Installation升級安裝，將可以保持原來的序列號，不必再次輸入 3.選擇Full安裝，Next->Yes(接受版權信息)->選擇安裝目錄->Next->輸入序列號、姓名、公司等，除了序列號以外，都隨意，可以如實輸入你的姓名等。->next-> ....直到安裝完成。注意： 1.每次安裝都必須進行這幾步，每次都需要重新寫入AddOn標識； 2.假如安裝過程中存在病毒防火墻，可能會產生xcopy錯誤使安裝失敗，此時請先關閉病毒防火墻，然后再安裝; 3.安裝前必須退出正在運行的Keil軟件，否則也會產生xcopy錯誤使安裝失敗； 4.安裝過程中可能會出現安裝Secrity Key錯誤，點擊確定即可。這組安裝碼可以使用keil C51軟件到2033年12月底，夠用了吧。 Ident = Y1DZKM (這個號碼已經輸入在addon目錄下的文件中，你不必理會了) SN = K1DZP-5IUSH-A01UE *************************************** 0xfd漢字補丁已經預先處理。安裝以后可以打開工程\keil\c51\examples\0xfd\ee.uv2檢驗
