DS1543W-120 Product Details
DS1543W-120 Overview
In the 28-DIP Module (0.600, 15.24mm) package, real time clocks is embedded.Tube is the way time clock is packaged.2.97V~3.63V is the supply voltage of this electrical RTC.Clock/Calendar is the type of this electrical real time clock.There is an real time clock (RTC) mounted in the way of Through Hole.0°C~70°C should be the operating temperature.Operating with Alarm, Leap Year, NVSRAM, Watchdog Timer are possible.In 28 terminations, a transmission line is terminated with an impedance-matched RTC module.3.3V voltage is present on this electronic component.With 28 pins, it is equipped.The DS1543 family contains RTCs .A memory of 8KB can be used to store data and programs.The output frequency should not exceed 0.032MHz.Mounting type is Through Hole.A total of 3.3V power supplies are required to operate it.
