X1205S8T1 Overview
A package named SOIC contains real time clocks.Tape & Reel (TR) is the packaging method.A transmission line can have a 8 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 5V voltage supplied to it.The RTCs are equipped with 8 pins.There should not be a frequency higher than 0.032MHz in the output.Mounting type for the RTC module is Surface Mount.A temperature above 0°C is recommended for operation.Lower than 70°C is the recommended operating temperature.5.5V 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.
