DS1501WE+ Overview
In package 28-TSSOP (0.465, 11.80mm Width), real time clocks can be found.In this case, time clock is packaged in the way of Tray.A voltage of 3V~3.6V is supplied to this electrical RTC.Electrical real time clock type Clock/Calendar.There is an electronic component mounted in the way of Surface Mount.Ideally, the operating temperature should be 0°C~70°C.During operation, the value of Alarm, Leap Year, NVSRAM, Square Wave Output, Watchdog Timer, Y2K can be ensured.It is possible to terminate transmission lines with 28 terminations, which means that the RTC module terminating the line matches its characteristic impedance.This electronic component receives a voltage of 3.3V.There are 28 pins on it.This object belongs to the family DS1501.There is 2.5V~3.7V supply voltage for this electrical digital time clock.A memory of 256B is embedded in the RTC times, which can be used to store programs and data.0.032MHz should be the maximum output frequency.A Surface Mount mounting type is assigned to the RTC module.The real time clock is equipped with 28 pins.1 timers are control real time clocks that emits a signal after receiving an input signal at a predetermined time.A high efficiency supply voltage should be maintained at 3.3V.
