DS1743

Y2K兼容、非易失时钟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、非易失时钟RAM

DS1744是功能完备、2000年兼容(Y2KC)的实时时钟/日历(RTC)和32k x 8 NV SRAM。用户可通过如完整数据资料中的图1所示的单字节宽度的接口对DS1744内部的所有寄存器进行访问。RTC信息和控制位占用RAM中最高的8个地址。RTC寄存器包含世纪、年、月、日、星期、小时、分和秒数据,采用24小时BCD格式。器件可自动对每个月份及闰年进行日期校正。RTC时钟寄存器采用双缓冲,可避免在时钟更新周期内访问不正确的数据。双缓冲系统还可以防止访问时间寄存器时导致倒数计时无法减少而引起的时间丢失。DS1744还包含电源失效电路,用于当VCC电源超出容差时,禁止选通器件。由于低VCC • 集成的NV SRAM、实时时钟、晶体、电源失效控制电路和锂电池\n• 访问时钟寄存器方式与静态RAM完全相同,这些寄存器位于RAM中最高的8个地址\n• 世纪字节寄存器;Y2K兼容\n• 完全的非易失性,可在缺少电源的条件下工作10年以上\n• BCD编码的世纪、年、月、日、星期、小时、分和秒数据,可自动进行闰年补偿至2100年\n• 电池电压指示标志\n• 电源失效写保护,允许±10%的VCC电源容差\n• 锂电池处于开路的保鲜模式,直至首次电源加电\n• 仅对于DIP模块\n• 标准的JEDEC字节宽度32k x 8静态RAM引脚排列\n\n\n• 仅对于PowerCap模板\;
