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

FEATURES

Integration of LEDs, LED controller and advanced communication link in one small 3 mm package
