Fudan Micro is a company that focuses on the design, development, testing and production of VLSI, and is able to provide comprehensive system solutions for the industry. The FM33FG065A MCU used at the core of this solution is a product of Fudan Micro. This product has excellent energy management and stability, can effectively control the power consumption of LEDs, and ensure 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 uses the OSIRE® E3731i RGBi product from ams OSRAM, which is an integrated intelligent RGB LED based on an open protocol. It can achieve a wide range of color choices and provide more design possibilities for automotive atmosphere lights.

In addition, the solution also uses the CA-IF1021D automotive-grade LIN transceiver and CA-IF1044VD CAN transceiver from Chuan Tuwei and the Richtek RTQ2945GSP DC/DC converter. With these products, this solution has achieved a qualitative leap in light and shadow effects, with rich colors and natural transitions, and can also create a more personalized in-car environment through intelligent adjustment.
