【Lansheng Technology News】WPI recently announced that its subsidiary Shiping has launched an automotive taillight solution based on NXP S32K144, Nanochip NSL21912 and Lextar Electronics PC35R14.
Under the general trend of automobile digital transformation, automobile taillights, as important devices for lighting and signaling, are also developing in a more intelligent, multi-functional and personalized direction. Currently, some well-known automobile manufacturers are using digital taillight design to automatically adjust light brightness and color to improve driving safety. In response to this trend, WPI launched an automotive taillight solution based on NXP S32K144, Nanochip NSL21912 and Lextar PC35R14, which can help automakers quickly complete through-type taillight designs and enhance the travel experience.
This solution consists of three parts: main control board, driver board and light board. Among them, the main control board is designed based on NXP's S32K144 MCU. S32K144 32-bit automotive-grade general-purpose MCU launched with Arm® Cortex®-M4F core. This product has a DSP instruction set and a single-precision floating-point processing unit (FPU), which can run at a maximum frequency of 112MHz, and integrates 2MB Flash and 256KB SRAM. It is suitable for automotive ASIL B/D body and area control applications.
The driver board of the solution uses Nanochip NSL21912 LED driver as the core, and is equipped with Nanochip NCA1042 CAN transceiver and JWQ5103 buck regulator. Among them, NSL21912 is a 12-channel, 20V high-side LED driver that complies with automotive grade Grade 1 and has an ambient temperature of up to 125°C. It is suitable for automotive exterior taillights, external headlights, and miscellaneous exterior lighting applications.
The lamp board is designed with 106 lamp beads, all of which use Lextar's PC35R14. With signal control, a variety of lighting effects can be achieved. In addition, the main control board, driver board and light board are connected using Molex connectors, which can quickly transmit control signals.
Benefiting from consumers' continuous pursuit of automobile appearance and safety performance, and automobile manufacturers' continuous exploration of new technologies, digital taillight design will become an important growth point in the automobile industry. In this regard, WPI will work with major partners to help manufacturers rapidly innovate and improve market competitiveness.
