Cypress Semiconductor Corporation assumes no responsibility for the use of any circuitry other than circuitry embodied in a
Cypress product. Nor does it convey or imply any license under patent or other rights. Cypress 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. Furthermore, Cypress 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 products in life-support systems application implies that the manufacturer assumes all risk of such
use and in doing so indemnifies Cypress against all charges.

Purchase of I2C components from Cypress or one of its sublicensed Associated Companies conveys a license under the
Philips I2C Patent Rights to use these components in an I2C system, provided that the system conforms to the I2C Standard

Flash Code Protection

Cypress products meet the specifications contained in their particular Cypress PSoC Data Sheets. Cypress believes that its
family of PSoC 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 guaranteeing 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.
