PCA9701PW Frequently Asked Questions (FAQs)

  • 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 minimize electromagnetic interference (EMI).
  • To configure the PCA9701PW for I2C bus stretching, set the STB pin high and ensure that the SCL pin is pulled up to VCC. The device will then stretch the clock signal to allow for slower slave devices on the bus. Refer to the datasheet section 8.3.1 for more details.
  • The PCA9701PW can drive a maximum capacitive load of 400 pF on the SDA and SCL lines. Exceeding this limit may result in signal degradation or non-compliance with I2C bus specifications.
  • To implement clock synchronization, connect the SCL pin to an external clock source and set the ECS pin high. The PCA9701PW will then synchronize its internal clock with the external clock signal. Refer to the datasheet section 8.3.2 for more details.
  • The recommended power-up sequence for the PCA9701PW is to apply VCC first, followed by the input signals (SCL, SDA, etc.). This ensures that the device powers up correctly and minimizes the risk of latch-up or other issues.
