PCF85053ATKJ Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VDD first, followed by VBAT. This ensures that the internal voltage regulator is enabled before the battery voltage is applied.
  • To configure the PCF85063ATKJ for a 12-hour clock format, set the 12/24 hour mode bit (bit 6 of register 0x02) to 0. This will enable the 12-hour clock format with AM/PM indication.
  • The RST pin is an active-low reset input that resets the device when pulled low. It can be used to reset the device to its default state or to recover from a fault condition.
  • The clock data can be read from the PCF85063ATKJ by accessing the time and date registers (registers 0x00 to 0x07) through the I2C interface. The data is stored in BCD format and must be converted to binary format for use in the application.
  • The typical current consumption of the PCF85063ATKJ is around 0.5 μA in standby mode and 1.5 μA in active mode, depending on the operating frequency and other factors.
