I2C interface and low power consumption RTC

The PT7C43390 is a CMOS I2C-bus real-time clock IC,which operates with the very low current consumptionand in the wide range of operation voltage. Theoperation voltage is 1.35 V to 5.5 V so that the RTC canbe used for various power supplies from main supply tobackup battery. In the system which oper Low current consumption: 0.3μA typ. (VDD=3.0V, TA = 25°C)\nWide operating voltage range: 1.35 to 5.5 V\nMinimum time keeping operation voltage: 1.25 V\nBuilt-in clock adjustment function\nBuilt-in free user register\n2-wire (I2C-bus) CPU interface\nBuilt-in alarm interrupter\nBuilt-in flag generator;
