MAX6909EO33+T Product Details
MAX6909EO33+T Overview
There is an embedded version of real time clocks in the package 20-SSOP (0.154, 3.90mm Width).This package has a package type of Tape & Reel (TR).Electrical RTCs such as this have a 3V~3.6V supply.In this case, we are dealing with an electrical real time clock that has a type of Clock/Calendar/Supervisor.It should be noted that the real time clock (RTC) is mounted in the way of Surface Mount.There are 20 terminations for transmission lines, which means that the RTC module that terminates the line matches its characteristic impedance.This RTC real time clock has a voltage supply of 3.3V which is provided to it.A total of 20 pins are attached to this RTCs.There are a family named MAX6909 that consarets of the RTCs .In the RTC times, there is a memory of 31B that is available for storing programs as well as data.Operating temperatures should be greater than -40°C.A temperature lower than 85°C should be used for operating.As soon as the maximum supply voltage (Vsup) of 3.6V is reached, the circuit is off.Normal operation requires a supply voltage (Vsup) greater than 3V.
