低電流SPI/3線RTC

DS1343/DS1344低電流實時時鐘(RTC)是一款計時器件，具有超低待機電流，能夠在備份電源供電時保持更長的使用壽命。器件支持高ESR晶體，從而擴展了器件的晶體選擇范圍。時鐘/日歷部分提供秒、分、時、星期、日期、月和年信息。對于少于31天的月份，可在月末自動調(diào)整日期，包括閏年修正。時鐘部分工作于24小時制式或帶/AM/PM指示的12小時制式。\n\n 可通過SPI?或3線接口串行傳輸?shù)刂泛蛿?shù)據(jù)。器件具有兩個可編程定時鬧鐘，每個鬧鐘可對秒、分、小時、星期組合設(shè)置產(chǎn)生中斷。如果不需要鬧鐘功能，則在一個或多個字段中將插入一些“無關(guān)”項?？梢栽O(shè)置定時鬧鐘觸發(fā)兩個不同的中斷輸出，或者將其 ? 250nA (典型值)低計時電流\n? 允許使用ESR高達100kΩ的晶體 \n? 器件支持6pF或12.5pF晶體\n?

Low-Current SPI/3-Wire RTCs Low Timekeeping Current of 250nA (typ)

General Description The DS1343/DS1344 low-current real-time clocks (RTCs) are timekeeping devices that provide an extremely low standby current, permitting longer life from a backup supply source. The devices also support high-ESR crystals, broadening the pool of usable crystals for the devices.
