OTP Fuse Programming
The i.MX RT1052 MCU has on-chip OTP fuses that can be programmed, see NXP documents
IMXRT1050CEC, .MX RT1050 Crossover Processors for Consumer Products - Data Sheet
and
IMXRT1050RM, i.MX RT1050 Processor Reference Manual
for details. Once programmed, there is no
possibility to reprogram them.
iMX RT1052 OEM Boards
are delivered without any OTP fuse programming. It is completely up to the
OEM board user to decide if OTP fuses shall be programmed and in that case, which ones.
Note that Embedded Artists does not replace iMX RT1052 OEM Boards because of wrong OTP
programming. It’s the user’s responsibility to be absolutely certain before OTP programming
and not to program the fuses by accident.

CE Assessment
The
iMX RT1052 Developers Kit
(consisting of the
iMX RT1052 OEM Board
and
iMX OEM Carrier
Board
) is CE marked. See separate
CE Declaration of Conformity
document.
The
iMX RT1052 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
iMX RT1052 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
iMX RT1052 Developers Kit
.
Due to the nature of the
iMX RT1052 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
iMX RT1052 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
integration into, is however very likely to need CE marking.
