ABSTRACT:
A low power timekeeping system utilizes a state machine to first read seconds stored in a RAM and update seconds and then determine if the minutes requires updating. If the minutes do not require updating then the sequencer stops operation until the next update cycle. Similarly, the minutes, hours, days of the week, date of the month, month, and year are updated only as needed in each update cycle thereby lowering the power requirement needed by the timekeeping system.
