SC18IS600IPW Frequently Asked Questions (FAQs)

• What is the maximum clock frequency for the I2C bus?
  The maximum clock frequency for the I2C bus is 400 kHz, but it can be operated at lower frequencies as well, such as 100 kHz or 10 kHz, depending on the application requirements.
• How do I configure the I2C bus for 10-bit addressing?
  To configure the I2C bus for 10-bit addressing, you need to set the 10-bit address mode bit (ADMB) in the control register (CTRL) to '1'. Additionally, you need to set the 10-bit address bits (A9-A0) in the address register (ADDR) accordingly.
• What is the purpose of the reset pin (RST) and how do I use it?
  The reset pin (RST) is an active-low input that resets the device when pulled low. It can be used to reset the device during power-up or to recover from a fault condition. To use it, simply pull the RST pin low for a minimum of 10 ns to reset the device.
• How do I handle I2C bus arbitration and clock stretching?
  The SC18IS600IPW has built-in arbitration logic to handle I2C bus contention. When two or more devices try to access the bus simultaneously, the device with the highest priority (determined by the address) wins the arbitration. Clock stretching is also supported, allowing slower devices to slow down the clock to match their processing speed.
• What is the power consumption of the SC18IS600IPW?
  The power consumption of the SC18IS600IPW depends on the operating mode and frequency. In active mode, the typical current consumption is around 1.5 mA at 3.3 V and 400 kHz I2C clock frequency. In standby mode, the current consumption is typically around 10 μA.
