MCP79521-I/MS Overview
A package named 10-TFSOP, 10-MSOP (0.118, 3.00mm Width) contains real time clocks.Tube is the packaging method.There is 1.8V~3.6V supply voltage for this electrical RTC.Electrical real time clocks of this type are Clock/Calendar.real time clock (RTC)s like this are mounted in the way of Surface Mount.-40°C~85°C is the operating temperature.When operating, you can ensure Alarm, EEPROM, Leap Year, Square Wave Output, SRAM, Unique ID.A transmission line can have a 10 termination by terminating it with a RTC module whose characteristic impedance matches the line's.In the case of this RTC real time clock, there is 3V voltage supplied to it.The RTCs are equipped with 10 pins.MCP79521 is the family name of this object.This electrical digital time clock is powered by 1.3V~3.6V voltage.It is included as part of Clock & Timer ICs.Programs and data can be stored in the 64B memory embedded in the RTC times.There should not be a frequency higher than 5MHz in the output.10 pins are attached to it.Optimal efficiency requires a supply voltage of 2.5, 3.3 V.A temperature above -40 °C is recommended for operation.Lower than 85 °C is the recommended operating temperature.Real time clocks operate with a voltage of 1.8 V.There is 3.6 V maximum supply voltage for real time clocks.Real time clocks of the series -- are of this type.An electrical real time analog clock like this has a type TIMER, REAL TIME CLOCK for uPs/uCs/Peripheral ICs.There are also ALSO OPEARTES AT 1.8V MIN SUPPLY AT 3MHZ CLOCK FREQ characteristics.
