Flash Code Protection 

Cypress products meet the specifications contained in their particular Cypress Datasheets. Cypress believes that its family 
of products is one of the most secure families of its kind on the market today, regardless of how they are used. There may 
be methods, unknown to Cypress, that can breach the code protection features. Any of these methods, to our knowledge, 
would  be  dishonest  and  possibly  illegal.  Neither  Cypress  nor  any  other  semiconductor  manufacturer  can  guarantee  the 
security of their code. Code protection does not mean that we are guaran

teeing the product as “unbreakable.” Cypress is 

willing to work with the customer who is concerned about the integrity of their code. Code protection is constantly evolving. 
We at Cypress are committed to continuously improving the code protection features of our products.
