MCP795W21-I/ST Overview
The package 14-TSSOP (0.173, 4.40mm Width) contains real time clocks.The package is in the form of Tube.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, Watchdog Timer 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 14 termination.Obviously, a voltage of 5V is being supplied to this electronic component.There are 14 pins on it.The family RTCs belongs to are MCP795W21.This electrical digital time clock has a 1.3V~3.6V supply voltage.For storing data and programs, the RTC times embed a memory of 64B.Real time clocks' output frequency should not exceed 10MHz.Surface Mount is the mounting type of the RTC module.There are 2/5V power supplies attached to it.It is equipped with 14 pins.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 5.5 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 1.8 V MINIMUM SUPPLY AT 3 MHZ are also characteristics of it.A 8 bit digital time clock is designed for this application.
