Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip 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.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Microchip received ISO/TS-16949:2009 certification for its worldwide
headquarters, design and wafer fabrication facilities in Chandler and
Tempe, Arizona; Gresham, Oregon and design centers in California
and India. The Company’s quality system processes and procedures
are for its PIC®MCUs and dsPIC®DSCs, KEELOQ®code hopping
devices, Serial EEPROMs, microperipherals, nonvolatile memory and
analog products. In addition, Microchip’s quality system for the design
and manufacture of development systems is ISO 9001:2000 certified.

Safety Notice
The following safety notices and operating instructions should be adhered to avoid a
safety hazard. If in any doubt, consult your supplier.
DANGER – The Digital Power Starter Kit contains two resistive loads that are intended
to dissipate power in the form of heat. Depending on the output power level, it is pos-
sible for the resistive load to become hot to the touch or to any surface in direct contact
with the board.
WARNING – The Digital Power Starter Kit should only be installed, operated, serviced
or modified by qualified personnel. Any service or modification performed by the user
is done at the user’s own risk and voids all warranties.
CAUTION – Particular care should be taken during code development as unexpected
voltage regulation behavior is possible. Ensure that the power supply connected to the
Digital Power Starter Kit is properly protected against overcurrent event caused by
code development.
General Notices:
• The Digital Power Starter Kit is intended for evaluation and development purposes
and should only be operated in a normal laboratory environment as defined by
IEC 61010-1:2001.
• Clean with a dry cloth only.
• Operate flat on a bench away from any surface items that might become in con-
tact with the board. Do not move during operation and avoid direct contact with
the bottom layer of the board.
• The Digital Power Starter Kit should not be connected or operated if there is any
apparent damage to the unit.
