On July 11, 2024, Dalian University Holdings, a leading international semiconductor component distributor dedicated to the Asia Pacific market, announced that its subsidiary Pinjia has launched an OSIRE based on Infineon PSoC 4 microcontroller and AMS OSRAM? E3731i intelligent RGB LED and Chipanalog CA-IF1044 CAN transceiver IC for car touch atmosphere lighting solution.

With the continuous rise of consumers' demand for car interior quality and personalization, car ambient lighting has become a core highlight in car design. With rich colors, adjustable brightness, and versatile dynamic effects, car ambient lights can create a more comfortable and unique interior environment for drivers and passengers. At the same time, the innovation of automotive ambient lighting has also brought new market opportunities for car manufacturers, becoming an important innovation to attract consumers to purchase. In response to this trend, Da Da Da Da Pin Jia has launched a car touch atmosphere lighting solution based on Infineon PSoC 4 microcontroller, ams OSRAM OSIRE E3731i intelligent RGB LED, and Chuantu Microelectronics CA-IF1044 CAN transceiver IC.

The Infineon PSoC 4 is a highly scalable processor platform with highly programmable flexibility and an Arm? Cortex? - M0+high-performance processing core, equipped with programmable analog front-end, programmable digital logic, and advanced CAPSENSE? The user interface and low-power Bluetooth module can simplify the customer development process. At the same time, Infineon also provides a complete development tool - PSoC Creator IDE (Integrated Design Environment), to help users easily create intelligent, interconnected, and user-friendly differentiated products.

In terms of LED selection, is ams OSRAM OSIRE chosen for this solution? E3731i is an intelligent RGB LED (RGBi module) designed specifically for car ambient lighting. The product has a built-in driver and control IC, which can efficiently communicate with microcontrollers through SPI interfaces. At the same time, is Amex Osram also used for OSIRE? The E3731i product provides an open communication protocol (OSP). With OSP, can microcontrollers communicate with each OSIRE? E3731i sends instructions and obtains status to achieve high-precision color calibration and temperature compensation. In addition, the product supports daisy chain, with a maximum of 1000 LED lights connected in series on a single chain, and only requires a microcontroller for control. Thanks to this, car manufacturers are able to create unique dynamic lighting effects inside the car.

In terms of communication, the solution uses the Chuantu Microelectronics CA-IF1044 CAN transceiver IC, which has a low-power standby mode and supports the wake-up sequence defined by ISO11898-2:2016. And it integrates multiple protection functions internally, which can improve the stability of devices and CAN.

In addition, the solution also uses Infineon TLE42744DV50 LDO regulator system to provide stable and reliable voltage output. With the excellent performance of these devices, this solution can be combined with the intelligent connectivity function of automobiles to create an interior atmosphere with dynamic colors and dynamic lighting effects, setting a new benchmark for automotive interior design.

Core technological advantages:

Infineon provides comprehensive performance and safety testing for PSoC and has been widely used in many mass-produced models, gaining market recognition;

PSoC has a mature development plan and environment, which greatly reduces the difficulty of user development and shortens the development cycle;

The PSoC series covers multiple options such as 4000S, 4100S, 4100S MAX, providing a wide range of directions for functional selection;

AMS OSRAM intelligent RGB LED, with rich connection methods and the scalability of a single link of 1000PCS, greatly reduces development costs. By converting multiple control channels into one link or DCU, all LEDs in the vehicle can be driven.

Scheme specifications:

This solution adopts Infineon PSoC&LDO, Chuantu Microelectronics CAN transceiver, and ams OSRAM intelligent RGB LED;

Communication methods: CAN, I2C, SPI, and debugging interface SW;

Functional aspects: PSoC CAPSENSE (PSoC comes with capacitance detection function for touch buttons, liquid detection and other solutions, supporting up to 300pf capacitance detection), PWM LED (ordinary light-emitting diode), SPI RGBi (multifunctional, safety detection, daisy chain);

Multi power input: Supports simultaneous connection of Type-C interface and 5525DC interface, or using one of them separately to power the entire solution, which is convenient for debugging and will not cause voltage conflicts.
