Security

 — Customer understands that all NXP products may be subject to

unidentified vulnerabilities or may support established security standards or

specifications with known limitations. Customer is responsible for the design

and operation of its applications and products throughout their lifecycles

to reduce the effect of these vulnerabilities on customer’s applications

and products. Customer’s responsibility also extends to other open and/or

proprietary technologies supported by NXP products for use in customer’s

applications. NXP accepts no liability for any vulnerability. Customer should
