PCA9421UKZ Frequently Asked Questions (FAQ)

  • NXP provides a recommended PCB layout in the application note AN11588, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and reliability.

  • The PCA9421UKZ supports I2C bus stretching, which allows the slave device to slow down the clock speed. To configure bus stretching, set the BST bit in the Control Register (CR) to '1'. The slave device can then stretch the clock by pulling the clock line low.

  • The maximum cable length supported by the PCA9421UKZ depends on the clock frequency and the type of cable used. As a general guideline, NXP recommends a maximum cable length of 1 meter for clock frequencies up to 400 kHz, and 0.5 meters for clock frequencies above 400 kHz.

  • The PCA9421UKZ has built-in hot-swapping capability, which allows devices to be connected or disconnected without causing damage to the bus. To handle hot-swapping, ensure that the VCC pin is connected to a power supply that can handle the inrush current, and use a pull-up resistor on the SCL and SDA lines to prevent bus contention.

  • The PCA9421UKZ has a built-in power-on reset (POR) circuit that resets the device after power-up. The POR timing is typically around 1 ms, but can vary depending on the power supply ramp-up time and the device's internal reset circuitry.
