MCP79521T-I/MN Overview
The package 10-WFDFN Exposed Pad contains real time clocks.The package is in the form of Tape & Reel (TR).This electrical RTC has a supply voltage of 1.8V~3.6V.This electrical real time clock has the type Clock/Calendar.Surface Mount is the way this real time clock (RTC) is mounted.Electronic time clocks are recommended that the operating temperature be -40°C~85°C.When operating, Alarm, EEPROM, Leap Year, Square Wave Output, SRAM, Unique ID can be ensured.It is possible to terminate a transmission line with a RTC module that matches the characteristic impedance of the line, which is known as 10 termination.Obviously, a voltage of 3V is being supplied to this electronic component.There are 10 pins on it.The family RTCs belongs to are MCP79521.This electrical digital time clock has a 1.3V~3.6V supply voltage.Clock & Timer ICs includes this part.For storing data and programs, the RTC times embed a memory of 64B.Real time clocks' output frequency should not exceed 5MHz.Surface Mount is the mounting type of the RTC module.It is equipped with 10 pins.In order to achieve high efficiency, the supply voltage should be kept at 2.5, 3.3 V.Ideally, the operating temperature should be higher than -40 °C.Ideally, the operating temperature should be lower than 85 °C.The minimal supply voltage is 1.8 V.A maximum supply voltage of 3.6 V is used.It is a type of real time clock belonging to the -- series.This electrical real time analog clock has the type TIMER, REAL TIME CLOCK of uPs/uCs/Peripheral ICs.ALSO OPEARTES AT 1.8V MIN SUPPLY AT 3MHZ CLOCK FREQ are also characteristics of it.
