DS1343E-3+ Overview
In the 20-TSSOP (0.173, 4.40mm Width) package, real time clocks is embedded.Tube is the way time clock is packaged.2.7V~5.5V is the supply voltage of this electrical RTC.Clock/Calendar is the type of this electrical real time clock.There is an real time clock (RTC) mounted in the way of Surface Mount.-40°C~85°C should be the operating temperature.Operating with Alarm, Leap Year, NVRAM, Square Wave Output, Trickle Charger are possible.In 20 terminations, a transmission line is terminated with an impedance-matched RTC module.3V voltage is present on this electronic component.With 20 pins, it is equipped.The DS1343 family contains RTCs .This electrical digital time clock has a supply voltage of 1.3V~5.5V.A memory of 96B can be used to store data and programs.The output frequency should not exceed 4MHz.Mounting type is Surface Mount.A total of 3V power supplies are required to operate it.There are 20 pins on it.An input signal is received by 1 timers, which output a signal after a preset time.High efficiency requires a 3V supply voltage.
