DS1556WP-120IND+ Overview
Real time clocks is embedded in the 34-PowerCap™ Module package.Time clock is packaged in the way of Tube.The supply voltage of this electrical RTC is 2.97V~3.63V.The type of this electrical real time clock is Clock/Calendar.This real time clock (RTC) is mounted in the way of Surface Mount.The operating temperature should be -40°C~85°C.Alarm, Leap Year, NVSRAM, Watchdog Timer, Y2K can be ensured when operating.There are 34 terminations, which are the practice of ending a transmission line welectronic time clocksh a RTC module that matches the characteristic impedance of the line.The supply voltage of this RTC real time clock is 3.3V.It is equipped with 34 pins.RTCs belongs to DS1556 family.The supply voltage of this electrical digital time clock is 3V.The RTC times embed a memory of 128KB available for storing programs and data.Real time clocks' output frequency should not exceed 0.032MHz.It is mounted in the way of Surface Mount.There are 34 pins, which are pronged contacts as part of a signal interface in a computer or other communications real time clock. The supply voltage should be maintained at 3.3V for high efficiency.
