MAX6909EO30+ Overview
20-SSOP (0.154, 3.90mm Width) contains real time clocks.A Tube package is used to package time clock.Its supply voltage is 2.7V~3.3V.It is a Clock/Calendar/Supervisor type electrical real time clock.A part of this electronic RTC module is mounted in the way of Surface Mount.Transmission lines can be terminated with 20 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 3V supplied to it.20 pins are present on it.A memory of 31B is embedded into the RTC times for storing programs and data.It reaches 3.3V when the maximal supply voltage (Vsup) is reached.For normal operation, Vsup must be above 2.7V.Temperatures should be kept below 85°C.
