YPRES, Belgium, October 14, 2010 /PRNewswire/ -- Melexis extends
its family of smart LIN slave IC's with a new Generation of
reconfigurable LIN switch slave. MLX80104 can be used to interface
with any door, roof, seat, steering wheel, dashboard, HVAC, light
control or similar switch module as well as for other application
require an easy access via LIN. The integration of LIN physical
layer, voltage regulator and integrated application IO's results in
a reduction in component cost. The integration of LIN controller
and approved LIN driver make switch modules speak LIN in no
time.

Incorporating the Melexis LIN transceiver physical layer,
Melexis LIN ASSPs (Application Specific Standard Products)
guarantee world leading integrated ESD protection results. The LIN
protocol handler meets all LIN standards like LIN2.0, LIN2.1 as
well as SAE J2602. In close collaboration with car manufacturers
Melexis defines the configuration settings of the ASSPs to assure a
straightforward fit across different applications and car
platforms.
The MLX80104 is a fully integrated LIN slave one a single Die.
All necessary components like physical layer LIN tranceiver, LIN
controller, voltage regulator, application controller as well as
supporting functions like ADC, PWM generation as well as high
voltage capable IOs are integrated. This high integration level
reduces the BOM dramatically and enables the development of very
compact and small LIN slave modules.
Thanks to the well established Melexis dual task microcontroller
implementation, an already approved LIN driver can be used and the
application can completely decoupled from the LIN network load. For
application software an 16-bit RISC microcontroller is
integrated.
The MLX80104 draws less than 50uA of current in sleep mode and
it is wake up capable via the LIN Bus as well as via connected
switches or other wake up sources. The LIN slave supports switches
in matrix as well as single switch configuration connected to 18
available IOs. All IOs are high voltage resistant and therefore
also remote off module connections can be supported. Via eight
interrupt capable IOs rotary encoder are supported. Different
analog inputs can convert any analog signal like resistive encoders
and resistive switches. An internal battery monitor enables supply
voltage dependend functions.
To illuminate the switch module panel, 8 open drain PWM outputs
are available with configurable PWM base frequency from 45Hz to
45kHz. With a message from the LIN master the LED output intensity
can be adjusted according to OEM specific requirements.
All the above functions are implemented on one piece of silicon
in an very small 5x5mm QFN package. This enables together with a
minimum of external components LIN slave application on very small
PCB space.
"The MLX80104 is the perfect example of a LIN ASSP" says
Michael Bender, LIN product line
manager at Melexis. "From an application point of view it
incorporates state of the art application expertise with maximum
configurability into a miniature 5 by 5mm package. The integrated
functions gives all needed design freedom, whilst minimizing design
time and qualification effort.
There is absolutely no better choice in terms of risk, cost and
performance for switch suppliers that want to catch the LIN
wave"
