It tracks time in 24-hour HH:MM:SS format and calendar in YY-MM-DD-dd, with automatic leap-year correction. The part includes a trickle-charger for a backup battery, so the clock keeps running through a main-power loss. With a 2.7 V to 5.5 V supply range and industrial temperature rating (-40°C to 85°C), it fits embedded systems that need accurate timekeeping across power cycles — utility meters, industrial controllers, security panels, and data loggers. ## Lifecycle and compliance Listed as Active with ROHS3 compliance.","metaTitle":"DS1340C-3# RTC Clock/Calendar, I²C, 16-SOIC, Industrial Temp","metaDescription":"Maxim DS1340C-3# I²C real-time clock/calendar with trickle charger, leap-year compensation, 125µA timekeeping at 3.3V, -40 to 85°C.
