The Maxim DS1682S+ is an Elapsed Time Counter (ETC) in an 8-pin SOIC package. It tracks cumulative time on a binary counter, not calendar date/time — this is the key distinction from a real-time clock. The part communicates over an I²C (2-wire serial) bus and integrates 10 bytes of EEPROM for storing calibration data, serial numbers, or configuration flags, plus an alarm output that can be set to trigger at a programmed elapsed time.

Frequently asked questions
Can DS1682S+ be used as a real-time clock?
No — the DS1682S+ is an Elapsed Time Counter, not a real-time clock. It tracks cumulative time on a binary counter, not calendar date or wall-clock time. For calendar/clock functions, you would need a dedicated RTC part.
