1. Product OverviewLED technology enables smaller form factors, higher power levels, longer lifespans, and lower power consumption, thus meeting the demands of advanced automotive lighting applications.
Figure 1 Hardware Diagram of LED Matrix Headlight for CKS32F407
The CKS32 series 32-bit automotive microcontroller (MCU) provides Arm® Cortex®-M based MCUs. It features scalability in terms of core, memory, and peripherals, achieving high performance and functional safety, compliant with ISO 26262 standards, reaching ASIL B safety level.
Table 1 LED Matrix Headlight Solution CKS32 Automotive MCU2. Functional FeaturesThe MCU receives control commands from the vehicle’s lighting control domain ECU via CAN. Referring to Figure 1 hardware solution, the MCU communicates with the LED driver chip through the UART hardware abstraction layer and CAN physical layer, ensuring communication reliability. One UART communicates with two MPQ7225 chips to control four dynamic lights, while another UART communicates with two N32LT3365 chips to control two LED matrix headlights. The control content includes the on/off state of individual LEDs, brightness control, and fault handling.
