PCA2129T/Q900/2,51 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for PCA2129T?
  The recommended operating voltage range for PCA2129T is 2.7V to 5.5V.
• How do I configure the PCA2129T for I2C or SMBus interface?
  The PCA2129T can be configured for I2C or SMBus interface by setting the SCL pin high or low, respectively, during power-up or reset.
• What is the maximum clock frequency supported by PCA2129T?
  The PCA2129T supports clock frequencies up to 400 kHz for I2C and 100 kHz for SMBus.
• How do I handle bus contention and arbitration in PCA2129T?
  The PCA2129T has built-in bus contention and arbitration mechanisms. In case of contention, the device will automatically retry the transaction.
• What is the purpose of the reset pin (RST) in PCA2129T?
  The reset pin (RST) is used to reset the PCA2129T to its default state. It can be used to recover from errors or to initialize the device.
