Overview
The Kinetis EA lighting control solution is based on a Kinetis KEA128 MCU in a 64 LQFP package
and a MC10XS3425 eXtreme switch to control automotive lighting and diagnose the status of
the front headlamp with eXtreme switch; it is based on real automotive lights high and low beam,
turning and braking. Communication through the system is realized by SPI. Freescale transceivers
are implemented for LIN and CAN communication and also potentiometers are used to control the
light level and status of the bulbs.
Availability
The complete solution is available to designers at a cost of $39 USD. The kit inculdes a Kinetis
KEA128LEDLIGHTRD board, bill of materials, layout files, schematics and lighting software code
with documentation. The board features LEDs, potentiometers, user buttons, LIN and CAN
interfaces and SWD interface, all of these will accelerate debugging and lower development time
and save cost. Additional drivers and documentation are available on the Kinetis EA web pages
