Flash Code Protection
Note the following details of the Flash code protection features on Cypress MicroSystems devices.
Cypress MicroSystems products meet the specifications contained in their particular Cypress MicroSystems Data Sheets. Cypress MicroSystems 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 MicroSystems,
that can breach the code protection features. Any of these methods, to our knowledge, would be dishonest and possibly illegal. Neither Cypress MicroSystems nor any
other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as "unbreakable."
Cypress MicroSystems is willing to work with the customer who is concerned about the integrity of their code. Code protection is constantly evolving. We at Cypress Micro-
Systems are committed to continuously improving the code protection features of our products.
