PCA9959HNMP Frequently Asked Questions (FAQs)

  • NXP provides a recommended PCB layout in the application note AN11559, which includes guidelines for component placement, routing, and grounding to minimize EMI.
  • To daisy-chain multiple PCA9959HNMP devices, connect the SDA and SCL pins of each device in series, and use the A0, A1, and A2 address pins to set a unique address for each device. Refer to the datasheet for more information on address pin configuration.
  • The maximum cable length for I2C communication with PCA9959HNMP depends on the clock frequency, cable capacitance, and noise environment. As a general guideline, NXP recommends keeping the cable length below 1 meter for 400 kHz I2C clock frequency. For longer cable lengths, consider using I2C bus repeaters or buffers.
  • To troubleshoot I2C communication issues with PCA9959HNMP, use a logic analyzer or oscilloscope to monitor the SDA and SCL signals. Check for proper signal levels, clock frequency, and data transmission. Verify that the I2C address is correctly set and that there are no bus conflicts. Refer to the datasheet and application notes for more troubleshooting tips.
  • No, PCA9959HNMP is designed to operate with a 1.8V to 3.6V power supply. Using a 5V power supply may damage the device. If you need to interface with a 5V system, consider using a level translator or voltage regulator to step down the voltage.
