          DS1743

          Y2K兼容、非易失時鐘RAM

          The DS1743 is a full-function, year-2000-compliant (Y2KC), real-time clock/calendar (RTC) and 8k x 8 nonvolatile static RAM. User access to all registers within the DS1743 is accomplished with a bytewide interface as shown in Figure 1 in the full data sheet. The RTC information and control bits resi \n? Integrated NV SRAM, Real-Time Clock, Crystal, Power-Fail Control Circuit, and Lithium Energy Source \n? Clock Registers are Accessed Identically to the Static RAM. These Registers Reside in the Eight Top RAM Locations. \n? Century Byte Register \n? Totally Nonvolatile with Over 10 Years of Opera;

          DS1744

          Y2K兼容、非易失時鐘RAM

          DS1744是功能完備、2000年兼容(Y2KC)的實時時鐘/日歷(RTC)和32k x 8 NV SRAM。用戶可通過如完整數(shù)據(jù)資料中的圖1所示的單字節(jié)寬度的接口對DS1744內(nèi)部的所有寄存器進行訪問。RTC信息和控制位占用RAM中最高的8個地址。RTC寄存器包含世紀、年、月、日、星期、小時、分和秒數(shù)據(jù),采用24小時BCD格式。器件可自動對每個月份及閏年進行日期校正。RTC時鐘寄存器采用雙緩沖,可避免在時鐘更新周期內(nèi)訪問不正確的數(shù)據(jù)。雙緩沖系統(tǒng)還可以防止訪問時間寄存器時導致倒數(shù)計時無法減少而引起的時間丟失。DS1744還包含電源失效電路,用于當VCC電源超出容差時,禁止選通器件。由于低VCC ? 集成的NV SRAM、實時時鐘、晶體、電源失效控制電路和鋰電池\n? 訪問時鐘寄存器方式與靜態(tài)RAM完全相同,這些寄存器位于RAM中最高的8個地址\n? 世紀字節(jié)寄存器;Y2K兼容\n? 完全的非易失性,可在缺少電源的條件下工作10年以上\n? BCD編碼的世紀、年、月、日、星期、小時、分和秒數(shù)據(jù),可自動進行閏年補償至2100年\n? 電池電壓指示標志\n? 電源失效寫保護,允許±10%的VCC電源容差\n? 鋰電池處于開路的保鮮模式,直至首次電源加電\n? 僅對于DIP模塊\n? 標準的JEDEC字節(jié)寬度32k x 8靜態(tài)RAM引腳排列\(zhòng)n\n\n? 僅對于PowerCap模板\;
