PCF85103C-2T/00,11 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for PCF85103C-2T/00,11?
  The recommended operating voltage range for PCF85103C-2T/00,11 is 2.5V to 5.5V.
• How do I ensure reliable communication with the PCF85103C-2T/00,11 over I2C?
  To ensure reliable communication, make sure to use a pull-up resistor on the SCL and SDA lines, and ensure the I2C bus is properly terminated. Also, follow the I2C protocol timing specifications and avoid bus contention.
• What is the maximum clock frequency supported by the PCF85103C-2T/00,11?
  The PCF85103C-2T/00,11 supports clock frequencies up to 400 kHz.
• How do I handle the power-on reset (POR) and brown-out detection (BOD) features of the PCF85103C-2T/00,11?
  The POR and BOD features are enabled by default. To handle them, ensure a proper power-up sequence, and consider using an external reset circuit or a supervisory IC to monitor the power supply.
• What is the purpose of the internal oscillator in the PCF85103C-2T/00,11?
  The internal oscillator is used to generate the clock signal for the device's internal operations. It can be used as a clock source for the I2C interface, but it's not recommended for precise timing applications.
