Inova Semiconductors launches a new hybrid signal transceiver for automotive ISELED lighting and sensor networks

Inova Semiconductors recently announced the launch of a hybrid signal transceiver INLT220Q for automotive ISELED lighting and sensor networks (ILaS). This integrated circuit can establish a 2 Mbit/s and low latency daisy chain connection on a simple unshielded twisted pair cable (UTP) several meters long.
This device can build a centralized and robust automotive ISELED LED network through sensors and actuators. The onboard ILaS network can consist of up to 4079 independent addressable nodes. This network adopts a packet switching communication protocol. Nodes can be configured as INLT220Q devices for branch or client devices, such as ISELED smart LEDs or simple sensor subsystems connected through UTP cables.
By providing two cable interfaces (ISP, ESP) and one ISELED component interface (chip to chip, CSP), the transceiver IC provides high flexibility for creating branch networks. The other three GPIOs can be used to control sensors such as buttons and switches, as well as actuators such as tactile feedback vibration motors. The integrated DC/DC buck converter can be directly powered from the battery.
The INLT220Q ILaS transceiver also includes a temperature sensor and an A/D converter to monitor the operating voltage and ambient temperature of the device. In addition, it also integrates OTP memory, where users can store product related information (manufacturer ID, batch number, etc.) as well as network addresses. This means that even if individual components fail, the remaining network devices can still be controlled without adjusting the addressing table in the software. OTP memory can be programmed through the ILaS protocol and can be completed by suppliers or device manufacturers themselves.
The reliability of this equipment has passed AEC-Q100 qualification certification, with a working temperature range of -40 ° C to+105 ° C. Integrated electricity provided by Inova
The road adopts a 5mm x 5mm x 0.8mm wetQFN-20 package with a spacing of 0.65mm. INLT220Q now offers samples and small batch products, which can be purchased worldwide without royalties
