Digital LED system solution


  • Integration of LEDs, LED controller and advanced communication link in one small 3 mm package
    • system cost reduction
  • Calibration of LED and driver during production process of LED module
    • no binning classes, no bar coding – calibration data stored in LED
    • no look up tables in µC anymore
    • system assembly using LED from the tape with guaranteed parameters
  • Bi-directional communication between µC and LED module with lowest latencies
    • EMI robust design based on 2 Mbit/s communication - no dedicated clock
    • LED temperature can be diagnosed individually by µC
    • efficient use of bandwidth due to individual addressing of each LED


  • Automotive Interior Lighting
  • Automotive Ambient Lighting
  • Roof Lighting
