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
Specification as defined by Philips. As from October 1st, 2006 Philips Semiconductors has a new trade name - NXP Semicon-
ductors.
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 guaran-
tee 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.

Safety Information
The “High Voltage Programmable Power Line Communication Development Kit” CY3274 is intended
for use as a development platform for hardware or software in a laboratory environment. The board
is an open system design, which does not include a shielded enclosure. Due to this reason the board
may cause interference to other electrical or electronic devices in close proximity. In a domestic
environment, this product may cause radio interference. In such cases, the user may be required to
take adequate preventive measures. Also, this board should not be used near any medical
equipment or RF devices.
Attaching additional wiring to this product or modifying the product operation from the factory default
may affect its performance and cause interference with other apparatus in the immediate vicinity. If
such interference is detected, suitable mitigating measures should be taken.
