DS1501WE+ Overview
In the package 28-TSSOP (0.465, 11.80mm Width), you will find real time clocks, and you will be able to install real time clocks.The package is in the form of Tray.This electrical RTC is powered by 3V~3.6V voltage.There is a type of electrical real time clock Clock/Calendar associated with this real time clock.It should be noted that the real time clock (RTC) is mounted in the way of Surface Mount.0°C~70°C should be the operating temperature.During operation, the value of Alarm, Leap Year, NVSRAM, Square Wave Output, Watchdog Timer, Y2K can be ensured.The 28 termination is the practice of terminating a transmission line with a RTC module matched to its characteristic impedance.In the case of this RTC real time clock, there is 3.3V voltage supplied to it.A total of 28 pins are attached to this RTCs.As a member of the DS1501 family, RTCs belongs to them.A crucial thing to remember is that this electrical digital time clock has a supply voltage of 2.5V~3.7V.It falls under the subcategory of Timers or RTCs.For the purpose of storing data and programs, the RTC times are embedded with a storage capacity of 256B.Real time clocks' output frequency should not exceed 0.032MHz.There is a mounting type of Surface Mount for this RTC module.A total of 28 pins are equipped with the real time clock.Following an input signal, there are 1 timers that output a signal at a preset time.High efficiency requires a 3.3V supply voltage.
