PCF2129AT/2,518 Frequently Asked Questions (FAQ)

  • The recommended crystal oscillator frequency for PCF2129AT is 32.768 kHz.

  • The PCF2129AT can be configured for 12-hour or 24-hour clock mode by setting the 12/24-hour mode bit (bit 6 of register 0x0E). Set the bit to '0' for 24-hour mode or '1' for 12-hour mode.

  • The RST pin on the PCF2129AT is an active-low reset input that resets the device when pulled low. It can be used to reset the device to its power-on state.

  • The PCF2129AT's registers can be read and written using the I2C interface. The device has a 7-bit slave address, and the registers can be accessed by sending the appropriate register address followed by the data to be written or read.

  • The power consumption of the PCF2129AT depends on the operating mode. In active mode, the typical current consumption is 0.5 μA, and in standby mode, it is 0.1 μA.
