PCF2123TS/1,112 Frequently Asked Questions (FAQs)

  • The recommended crystal oscillator frequency for PCF2123TS/1,112 is 32.768 kHz, which is a standard frequency for real-time clocks.
  • To configure the PCF2123TS/1,112 for battery-backed operation, connect a battery to the VBAT pin and ensure that the VCC pin is connected to a power source. The device will automatically switch to battery-backed mode when VCC is below the battery switch-over voltage (typically 1.5 V).
  • The maximum clock frequency that can be used with the PCF2123TS/1,112 is 1 MHz, which is the maximum frequency of the internal oscillator.
  • The PCF2123TS/1,112 can be reset by applying a low signal to the RST pin or by using the software reset command (writing 0x00 to the reset register).
  • The INT/SQW pin on the PCF2123TS/1,112 is a multifunction pin that can be used as an interrupt output or a square wave output. It can be configured to generate an interrupt signal or a square wave signal with a frequency of 1 Hz, 4 kHz, or 8 kHz.
