DS1558Y+TRL Overview
There is an embedded version of real time clocks in the package 48-LQFP.Electrical RTCs such as this have a 4.5V ~ 5.5V supply.In this case, we are dealing with an electrical real time clock that has a type of Clock/Calendar.It should be noted that the real time clock (RTC) is mounted in the way of Surface Mount.Electronic time clocks are recommended to operate at a temperature of -40°C ~ 85°C.In this electrical digital time clock, the supply voltage is 2.5V ~ 3.7V.This component can be found in Clock & Timer ICs.In the RTC times, there is a memory of - that is available for storing programs as well as data.The - series represents this type of real time clock.
