DS1501WS+ Product Details

DS1501WS+ Overview


In the 28-SOIC (0.295, 7.50mm Width) package, real time clocks is embedded.Tube is the way time clock is packaged.3V~3.6V 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 Surface Mount.0°C~70°C should be the operating temperature.Operating with Alarm, Leap Year, NVSRAM, Square Wave Output, Watchdog Timer, Y2K 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 DS1501 family contains RTCs .This electrical digital time clock has a supply voltage of 2.5V~3.7V.A memory of 256B can be used to store data and programs.The output frequency should not exceed 0.032MHz.A total of 3.3V power supplies are required to operate it.An input signal is received by 1 timers, which output a signal after a preset time.
