DS1747W-120+ Product Details

DS1747W-120+ Overview


32-DIP Module (0.600, 15.24mm) contains real time clocks.A Tube package is used to package time clock.Its supply voltage is 2.97V~3.63V.It is a Clock/Calendar type electrical real time clock.A part of this electronic RTC module is mounted in the way of Through Hole.Electronic time clocks should be 0°C~70°C degrees Celsius during operation.Electronic time clocks are possible to guarantee Leap Year, NVSRAM, Y2K when operating.Transmission lines can be terminated with 32 terminations, which means that the RTC module that terminates the line matches its characteristic impedance.In this RTC real time clock, there is a voltage of 3.3V supplied to it.32 pins are present on it.DS1747 are RTC s family.A memory of 512KB is embedded into the RTC times for storing programs and data.The power supply is 3.3V.With 32 pins, it is equipped.
