Inova Semiconductors in Germany has signed deals with NXP and Microchip to use the ILaS (ISELED Light & Sensor Network) protocol in microcontrollers as the technology reaches mainstream automotive designs.

The ILaS network enables packet switched communication between the microcontroller as initiator and the connected clients throughout a vehicle on a single pair UTP cable. All the devices connected to the ILaS bus such as smart ISELED LEDs, touch/proximity sensors or stepper motors are controlled via the ILaS protocol implemented in the microcontroller.

The ILaS network is deterministic, unlike other bus systems where all the control resides with the microcontroller. This makes IlaS suitable for modern network concepts such as zone architectures with centralized control. IlaS systems are due to go into series production in vehicles from 2025.

“Microchip’s 8-, 16- and 32-bit microcontroller portfolio, paired with our optimized ILaS SW stack provide higher data rates and flexibility to our customers. Combined with our automotive Ethernet portfolio such as our latest 10BASE-T1S products and with dedicated HMI ICs, we support complete solutions for innovative lighting applications and offer a fast and low-risk development path for our customers,” said Matthias Kaestner vice president of Microchip’s automotive products unit.

“The new ILaS protocol will enable car makers to enhance the driver and passengers’ comfort without breaking their architectures and can leverage the NXP’s S32K3 microcontrollers for zonal controllers to deliver a software-defined in-cabin experience”, said Manuel Alves, VP and General Manager of the General Purpose and Integrated Solutions product line at NXP.

“Inova has been pioneering innovations in the field of display links for many years” said Robert Kraus, CEO of Inova Semiconductors and Chairman of the ISELED Alliance. “In the car concepts of tomorrow, we recognize that light and display are converging. With our latest ISELED/ILaS technology next to our legacy APIX link for displays, we now also offer solutions to economically control the ever more increasing number of LEDs and sensors throughout the car.”
