M48T251Y-70PM1 Product Details
M48T251Y-70PM1 Overview
This can be found in the package 32-DIP Module (0.600, 15.24mm).The package is Tube.This electrical RTC receives its power from the 4.5V~5.5V supply voltage.There is a type of electrical real time clock Phantom Time Chip associated with this real time clock.Here, Through Hole represents how this part is mounted.Temperature should be set at 0°C~70°C.In order to ensure Leap Year when operating, a certain value has to be set.There is the possibility of terminating transmission lines with 32 terminations, which means that the equipment used to terminate the line will match its characteristic impedance.This RTC real time clock has a voltage of 5V.With 32 pins, it is equipped with the necessary functions.M48T251 are a family of objects that belongs to RTCs .It should be noted that the RTC times embed a memory of 3.9MB which is usable for storing programs and data as well.This RTC module is mounted using type Through Hole.It operates from 5V power supplies.There are 32 pins, which are pronged contacts as part of a signal interface in a computer or other communications real time clock. It is a type of real time clock belonging to the Timekeeper® series.The frequency that can be achieved is 70GHz.
