The EMC performance of an application using this microcontroller is dependent on a number of factors that are outside the control of NXP Semiconductor. These factors include but are not limited to industrial design, mechanical design, printed circuit board design and layout, components, connectors, and cables. NXP Semiconductor is unable to guarantee the EMC performance of any microcontroller in a specific application. Careful consideration must be made when designing any application to ensure the necessary level of EMC. For more information on designing robust EMC systems please refer to application note AN2764.
