Instrument Cluster
The information/status include gauges for various parameters,
indicators, and status-lights as well as acoustical effects.
• Displays range from small dot matrix up to large color, high
resolution LCD displays
In addition to CAN/LIN interface there are LVDS interfaces.
• LVDS interfaces are used to transfer large amounts of data via a high-
speed serial connection to an external location like a video screen.
The main load types in a Cluster are the stepper motors that operate
the gauges and the various indicator and back light sources.
• The Stepper motor drivers are typically integrated in the μC.
• LED drivers are typically multi-channel devices with serial interfaces to
the μC or Darlington arrays.
