MAX6909EO30+T Overview
There is a package 20-SSOP (0.154, 3.90mm Width) that contains real time clocks.Tape & Reel (TR) is the way in which time clock is packaged.As far as the supply voltage for this electrical RTC is concerned, it is 2.7V~3.3V.This electrical real time clock belongs to the Clock/Calendar/Supervisor category.The way this real time clock (RTC) is mounted on the system board is Surface Mount.With 20 terminations, transmission lines have the characteristic impedance of the RTC module terminating them.This RTC real time clock is powered by 3V volts.The board is equipped with a total of 20 pins.In the family MAX6909, RTCs are a member.For storing the programs and data, the RTC times have an embedded memory of 31B for storing data and programs.Ideally, the operating temperature should be higher than -40°C.Ideally, the operating temperature should be lower than 85°C.There is a maximum supply voltage (Vsup) of 3.3V.For normal operation, the supply voltage (Vsup) should be kept above 2.7V.
