PCA9545ADW Frequently Asked Questions (FAQs)

  • The PCA9545ADW can support I2C bus frequencies up to 400 kHz, but it's recommended to limit the frequency to 100 kHz for reliable operation.
  • To configure the PCA9545ADW for multi-master I2C bus operation, you need to connect the INT pin to the interrupt input of the microcontroller, and use the I2C bus arbitration mechanism to prevent data corruption. You can also use the PCA9545ADW's built-in bus arbitration feature by setting the ARB_EN bit in the control register.
  • The PCA9545ADW can support up to 8 devices on each channel, but the total number of devices on the I2C bus should not exceed 128 to avoid bus capacitance issues.
  • The PCA9545ADW can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state and clear all internal registers.
  • The PCA9545ADW powers on in a disabled state, with all channels disconnected from the I2C bus. You need to configure the device using the control register to enable the channels and set the desired operating mode.
