The MSM6542 is a perpetual-calendar-based real time clock with an alarm function which can read and write data in units of seconds. It can be connected to various buses and can function as a peripheral IC of a microcomputer. The clock ranges are seconds, minutes, hours, days, months, years, and days of the week. The alarm ranges are seconds, minutes, hours, .
• Real time clock providing seconds, minutes, hours, days, months, years, and days of the week.
• Multiple alarm ranges covering seconds, minutes, hours, days, months, and days of the week. A desired alarm range can be selected.
• A periodic interrupt output interval can be selected over a wide range from 1/1024 seconds up to 10 minutes.
• Interface flexibility allows for connection to many types of microprocessors.
• Single read-out procedure (Read flag).
• Single power sense circuitry. (Data protect function).
• Unused registers can be used as RAM.
• 30-second adjustment by software or hardw.
