MCP795B21-I/SL Overview
real time clocks is located in package 14-SOIC (0.154, 3.90mm Width).As of Tube, time clock is packaged in this way.There is 1.8V~5.5V voltage supply for this electrical RTC.It can be said that this electrical real time clock belongs to the Clock/Calendar type.The real time clock (RTC) that is mounted in the way of Surface Mount is connected to this circuit board.In order to operate properly, the temperature should be -40°C~85°C.During the course of operation, Alarm, EEPROM, Leap Year, Square Wave Output, SRAM, Unique ID, Watchdog Timer can be ensured.There is the possibility of terminating transmission lines with 14 terminations, which means that the equipment used to terminate the line will match its characteristic impedance.In this case, the voltage supplied to the electronic component is 5V.A total of 14 pins are included in this product.MCP795B21 are the family name of RTCs .As far as the supply voltage for this electrical digital time clock is concerned, it is 1.3V~5.5V.For the purpose of storing data and programs, the RTC times are embedded with a storage capacity of 64B.There should be no frequency greater than 10MHz in real time clocks' output.For powering the real time clock, a power supply with a voltage of 2/5V is used.It is a real-time clock in the series --.Additionally, it has the property of ALSO OPEARTES AT 1.8 V MINIMUM SUPPLY AT 3 MHZ.With 8 Bits, this digital time clock is designed.
