DS1553P中文资料64kB非易失、Y2K兼容时钟RAM数据手册ADI规格书

描述 Description

The DS1553 is a full-function, year-2000-compliant (Y2KC) real-time clock/calendar (RTC) with an RTC alarm, watchdog timer, power-on reset, battery monitor, and \"8k x 8 nonvolatile static RAM (NV SRAM).\" User access to all registers within the DS1553 is accomplished with a bytewide interface as shown in Figure 1. The RTC registers contain century, year, month, date, day, hours, minutes, and seconds data in 24-hour BCD format. Corrections for day of month and leap year are made automatically.

特性 Features

• Clock Registers are Accessed Identically to the Static RAM; These Registers are Resident in the 16 Top RAM Locations
• Precision Power-On Reset
• BCD-Coded Year, Month, Date, Day, Hours, Minutes, and Seconds with Automatic Leap Year Compensation Valid Up to the Year 2100
• Power-Fail Write Protection Allows for ±10% VCC Power-Supply Tolerance
• Lithium Energy Source is Electrically Disconnected to Retain Freshness Until Power is Applied for the First Time
