customer’s applications or products, or the application or use by customer’s 
third party customer(s). Customer is responsible for doing all necessary 
testing for the customer’s applications and products using NXP 

Semiconductors products in order to avoid a default of the applications and 
the products or of the application or use by customer’s third party 
customer(s). NXP does not accept any liability in this respect. 

Export control —
