ISELED ... Integrated Smart Embedded LED

 

  • Integrates the ISELED® LED driver with the RGB LEDs into a single Smart RGB LED component, which then allows:
    • Color calibration of the Smart RGB LED at the LED manufacturer instead of the system manufacturer
    • Internal temperature compensation within the module
    • Storage of the individual calibration & compensation values within the Smart RGB LED module
  • Integrates the bidirectional ISELED® communication protocol to allow:
    • 4K address space for individual or multicast addressing of any LED in a daisy-chaining configuration
    • Controlling the homogenous color of any RGB LED by a simple, digital 24-bit value instead of controlling 3-channel current & PWM.
    • Diagnostic read-back of individual internal parameters
  • ISELED® communication bus is optimized for RGB LEDs mounted on light strips on a PCB to meet automotive EMC requirements.
    • Short cable distances can be supported with external filters
  • Power efficient 5V supply only

ILaS … ISELED Light and Sensor Network

 

  • Cable connectivity solution of ISELED RGB LEDs and Sensors
    • 40V robust design that meets automotive ESD and EMC requirements
    • Single 12V power supply with integrated DCDC buck controller for power efficient 5V lighting implementation
    • Low power mode and wake-up signaling
    • Optimized for connectivity of LED-, sensor-, actuator-subsystems via unshielded cable
    • GPIOs for control of external devices.
  • Enhanced bidirectional ILaS® communication protocol:
    • Supports a physically segmented daisy-chain of ISELED® LEDs
    • High fault tolerance through network segmentation and transceiver bypath (Fail-over pass-through)
    • User space in OTP memory to store network topology information
