MAX6917 - I2C-Compatible RTC

General Description

The MAX6917 provides all the

Key Features

  • of a real-time clock (RTC) plus a microprocessor (µP) supervisory circuit, NV RAM controller, and backup-battery monitor function. In addition, 96 x 8 bits of static RAM are available for scratchpad storage. The MAX6917 communicates with a µP through an I2C-bus-compatible serial interface. The real-time clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including correcti.

19-3702; Rev 1; 10/05 MAX6917 I2C-Compatible RTC with Microprocessor Supervisor, Alarm, and NV RAM Controller General Description The MAX6917 provides all the features of a real-time clock (RTC) plus a microprocessor (µP) supervisory circuit, NV RAM controller, and backup-battery monitor function. In addition, 96 x 8 bits of static RAM are available for scratchpad storage. The MAX6917 communicates with a µP through an I2C-bus-compatible serial interface. The real-time clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap years through 2099. The clock operates in either 24hr or 12hr format with an AM/PM indicator.
