Important Notice

NXP provides the enclosed product(s) under the following conditions:
This evaluation kit is intended for use of ENGINEERING DEVELOPMENT OR EVALUATION PURPOSES ONLY. It is provided as a

sample IC pre-soldered to a printed circuit board to make it easier to access inputs, outputs, and supply terminals. This evaluation board
may be used with any development system or other source of I/O signals by simply connecting it to the host MCU or computer board via
off-the-shelf cables. This evaluation board is not a Reference Design and is not intended to represent a final design recommendation for
any particular application. Final device in an application will be heavily dependent on proper printed circuit board layout and heat sinking
design as well as attention to supply filtering, transient suppression, and I/O signal quality.

The goods provided may not be complete in terms of required design, marketing, and or manufacturing related protective considerations,
including product safety measures typically found in the end product incorporating the goods. Due to the open construction of the product,
it is the user's responsibility to take any and all appropriate precautions with regard to electrostatic discharge. In order to minimize risks
associated with the customers applications, adequate design and operating safeguards must be provided by the customer to minimize
inherent or procedural hazards. For any safety concerns, contact NXP sales and technical support services.

Should this evaluation kit not meet the specifications indicated in the kit, it may be returned within 30 days from the date of delivery and will
be replaced by a new kit.

NXP reserves the right to make changes without further notice to any products herein. NXP makes no warranty, representation or
guarantee regarding the suitability of its products for any particular purpose, nor does NXP assume any liability arising out of the
application or use of any product or circuit, and specifically disclaims any and all liability, including without limitation consequential or
incidental damages. Typical parameters can and do vary in different applications and actual performance may vary over time. All operating
parameters, including Typical, must be validated for each customer application by customer’s technical experts.

NXP does not convey any license under its patent rights nor the rights of others. NXP products are not designed, intended, or authorized
for use as components in systems intended for surgical implant into the body, or other applications intended to support or sustain life, or
for any other application in which the failure of the NXP product could create a situation where personal injury or death may occur.
