2.3 General Handling Care
Handle the LPC3250 OEM Board and OEM Base Board with care. The boards are not mounted in a
protective case/box and are not designed for rough physical handling. Connectors can wear out after
excessive use. The OEM Base Board is designed for prototyping use, and not for integration into an
end-product.
For boards with LCD, do not exercise excessive pressure on the LCD glass area. That will damage the
display. Also, do not apply pressure on the flex cables connecting the LCD/touch screen. These are
relatively sensitive and can be damaged if too much pressure is applied to them.
Note that Embedded Artists does not replace boards where the LCD has been improperly
handled.
2.4 LPC3250 Core Voltage Precaution
The core voltage for the LPC3250 can be dynamically changed, via I2C commands sent to the
LTC3447 voltage converter. The voltage can be set to up to 2V. Note that this is above the limits of the
core voltage. Read the LPC3250 datasheet for details (the absolute maximum core voltage allowed is
1.39V).
Note that Embedded Artists do not replace LPC3250 OEM boards where the core voltage
(V
DD(CORE)
) has been raised above 1.39 Volt. It is the user’s responsibility not to exceed the
voltage specification found in the datasheet.
2.5 CE Assessment
The LPC3250 Developers Kit (consisting of the LPC3250 OEM Board and OEM Base Board) is CE
marked. See separate CE Declaration of Conformity document.
The LPC3250 Developers Kit is a class A product. In a domestic environment this product may cause
radio interference in which case the user may be required to take adequate measures.
EMC emission test has been performed on the LPC3250 Developers Kit. Standard interfaces like
Ethernet, USB, serial have been in use. General expansion connectors where internal signals are
made available (for example processor pins) have been left unconnected. Connecting other devices to
the product via the general expansion connectors may alter EMC emission. It is the user’s
responsibility to make sure EMC emission limits are not exceeded when connecting other devices to
the general expansion connectors of the LPC3250 Developers Kit.
Due to the nature of the LPC3250 Developers Kit – an evaluation board not for integration into an end-
product – fast transient immunity tests and conducted radio-frequency immunity tests have not been
executed. Externally connected cables are assumed to be less than 3 meters. The general expansion
connectors where internal signals are made available do not have any other ESD protection than from
the chip themselves. Observe ESD precaution.
Note that the LPC3250 OEM board is classified as a component and is hence not CE marked
separately. It can perform different functions in different integrations and it does not have a direct
function. It is therefore not in the scope of the CE Directive. An end product, where an OEM Board is
integrated into, is however very likely to need CE marking.
2.6 Other Products from Embedded Artists
Embedded Artists have a broad range of LPC1000/2000/3000/4000 based boards that are very low
cost and developed for prototyping / development as well as for OEM applications. Modifications for
OEM applications can be done easily, even for modest production volumes. Contact Embedded Artists
for further information about design and production services.
2.6.1 Design and Production Services
Embedded Artists provide design services for custom designs, either completely new or modification to
existing boards. Specific peripherals and I/O can be added easily to different designs, for example,
