On November 21, 2024, Da Da Da Lian Holdings, a leading international semiconductor component distributor dedicated to the Asia Pacific market, announced that its subsidiary Pinjia has launched an automotive ambient lighting solution based on Fudan Micro FM33FG065A MCU and AMS OSRAM OSIRE E3731i RGBi LED.

Currently, automotive ambient lighting, as an important element to enhance interior quality, is gradually becoming a standard feature in modern car design. From simple lighting functions to rich and colorful emotional expressions, a revolution around automotive ambient lighting is slowly unfolding. In this context, Dalian University Pinjia has launched an automotive ambient lighting solution based on the Fudan Micro FM33FG065A chip and ams OSRAM OSIRE E3731i RGBi LED, which can create different driving atmospheres and enhance user experience by adjusting the color and brightness of the lights.

Fudan Microelectronics is a company dedicated to the design, development, testing, and production of ultra large scale integrated circuits, providing comprehensive system solutions for the industry. The FM33FG065A MCU used as the core of this solution is a product under Fudan Microelectronics. This product has excellent energy management and stability, which can effectively control the power consumption of LEDs, ensuring the reliability and durability of the lighting system. In addition, through the flexible interface control provided by FM33FG065A, precise dimming and color temperature adjustment of LEDs can be achieved to meet the lighting needs in different environments.

In terms of LED selection, this solution adopts the OSIRE E3731i RGBi product under ams OSRAM, which is an integrated intelligent RGB LED based on an open protocol that can achieve a wide range of color choices and provide more design possibilities for automotive ambient lights.

Not only that, the solution also uses CA-IF1021D automotive grade LIN transceiver and CA-IF1044VD CAN transceiver from Chuantu Micro, as well as a Liqi RTQ2945GSP DC/DC converter. With the help of these products, this solution has achieved a qualitative leap in light and shadow effects, not only with rich colors and natural transitions, but also through intelligent adjustment to create a more personalized in car environment.
