ISELED^® Protocol Ambient Lighting

In-vehicle LED lighting poses complex challenges for automotive designers. Innovative in-car lighting applications feature hundreds of LEDs, typically in the form of flexible light strips that consist of many single RGB LEDs that must be individually controlled to produce dynamic effects. In partnership with the open Intelligent Smart Embedded LED (ISELED) Alliance, we are overcoming these technical barriers by combining a broad portfolio of Microchip products into a total system solution for ISELED.

ISELED is an innovative technology based on highly integrated, smart LED modules that enable dynamic ambient and functional lighting solutions. ISELED greatly simplifies color design and connectivity and reduces system cost due to fully calibrated LEDs that don’t require binning. This solution enables the connection of up to 4,079 ISELED LEDs via a differential bus at a speed of 2 Mbps and controls them with a single external microcontroller (MCU).

In addition to the core MCU that enables the ISELED protocol, we offer power management and connectivity solutions to help you deliver a complete ISELED solution. While ISELED is used for PCB communication, ISELED Light and Sensor Network (ILaS) expands the use of the protocol to other components, such as sensors and actuators, and offers support for cables and longer-distance communication. Our solutions enable ISELED and ILaS and serve as gateways between LIN, CAN FD and Ethernet such as 10BASE-T1S.
