a registered trademark of Cypress Semiconductor Corp. All other trademarks or registered trademarks referenced herein are property of the respective corporations.
The information contained herein is subject to change without notice. Cypress Semiconductor assumes no responsibility for the use of any circuitry other than circuitry
embodied in a Cypress Semiconductor product. Nor does it convey or imply any license under patent or other rights. Cypress Semiconductor does not authorize its products
for use as critical components in life-support systems where a malfunction or failure may reasonably be expected to result in significant injury to the user. The inclusion of
Cypress Semiconductor products in life-support systems application implies that the manufacturer assumes all risk of such use and in doing so indemnifies Cypress
Semiconductor against all charges. Cypress Semiconductor products are not warranted nor intended to be used for medical, life-support, life-saving, critical control or safety
applications, unless pursuant to an express written agreement with Cypress Semiconductor.
Flash Code Protection
Note the following details of the Flash code protection features on Cypress Semiconductor PSoC devices.
Cypress Semiconductor products meet the specifications contained in their particular data sheets. Cypress Semiconductor 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 Semiconductor, that can breach the
code protection features. Any of these methods, to our knowledge, would be dishonest and possibly illegal. Neither Cypress Semiconductor 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 Semiconductor is willing to work with the customer who is concerned about the integrity of their code. Code protection is constantly evolving. We at Cypress
Semiconductor are committed to continuously improving the code protection features of our products.
