DS1685EN-3+T OverviewA transmission line can have a 24 termination by terminating it with a RTC module whose characteristic impedance matches the line's.In the case of this RTC real time clock, there is 3V voltage supplied to it.The RTCs are equipped with 24 pins.Programs and data can be stored in the 242B memory embedded in the RTC times.There should not be a frequency higher than 0.032MHz in the output.Mounting type for the RTC module is Surface Mount.There is a power supply of 3V used to power the real time clock.24 pins are attached to it.1 timers are used in this system. They output a signal after an input signal is received at a predetermined time.3.7V is the maximum supply voltage (Vsup).An electrical real time analog clock like this has a type TIMER, REAL TIME CLOCK for uPs/uCs/Peripheral ICs.As a rule of thumb, the supply voltage (Vsup) should never be below 2.7V.A temperature below 85°C°C should be maintained during operation.
