Freescale high-performance instrument control processor
Freescale high-performance instrument control processor
Freescale launched a series of cost-effective 16-bit microcontrollers designed specifically for the electronic dashboard of entry-level cars. Entry-level automotive applications are the fastest growing segment of the automotive industry. As the newest member of the expanding 16-bit MCU series of Freescale, the latest S12HY series combines economical and practical 16-bit performance and optimized functions, making it ideal for cost-sensitive dashboard applications in the emerging automotive market.
The car dashboard control system is the brain of the car dashboard, which controls various analog meters, display screens, LED indicators and audio signals. Its main function is to communicate with external data sources and control data output devices. With the increase in the number of data sources and the use of in-vehicle data connections, the dashboard control system also provides limited gateway functions.
