1 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,
