PT7C43390 - Real-time Clock Module

Description

The PT7C43390 is a CMOS I2C-bus real-time clock IC, which operates with the very low current consumption and in the wide range of operation voltage.

The operation voltage is 1.35 V to 5.5 V so that the RTC can be used for various power supplies from main supply to backup battery.

Features

  • Low current consumption: 0.3µA typ. (VDD=3.0V, TA = 25°C).
  • Wide operating voltage range: 1.35 to 5.5 V.
  • Minimum time keeping operation voltage: 1.25 V.
  • Built-in clock adjustment function.
  • Built-in free user register.
  • 2-wire (I2C-bus) CPU interface.
  • Built-in alarm interrupter.
  • Built-in flag generator at power down or power on.
  • Auto calendar up to the year 2099, automatic leap year calculation function.
  • Built-in constant voltage circuit.
  • Buil.
