MCU (Microcontroller Unit, microcontroller for short) is the basis of electronic control module (ECM), which is widely used in security systems, comfort driving systems, chassis systems, driving information systems and other fields. In the automotive electronics industry, the use of 8-bit and 16-bit MCUs is still expanding. In the automotive electronic system designed for upcoming models, 8-bit and 16-bit microcontrollers continue to account for more than 75%. Among the many challenges faced by embedded control designers, the two most important issues are how to bring the project to market faster and control development costs within budget. For the development strategy of most automotive embedded system developers and the supply strategy of ECM manufacturers, the correct choice of 8-bit or 16-bit MCU architecture is crucial. The choice of MCU will affect many aspects of design, procurement, production and sales. Automotive electronic module manufacturers are trying to reduce the number of their suppliers. Suppliers choose the right 8-bit or 16-bit MCU first to analyze the characteristics of the device itself, such as storage technology and capacity selection, I / O pins, on-chip peripherals, system throughput, power consumption, package selection, etc. In addition, suppliers must adopt a flexible MCU architecture to provide designers with easy-to-use and a wide range of compatible products, as well as a comprehensive development tool kit. The overall system performance requirements and the allocated MCU budget usually determine the type of 8-bit or 16-bit MCU most suitable for ECM development. Therefore, the best MCU partners should use a user-friendly architecture as the basis and provide a rich series of compatible devices to meet the needs of system developers for 8-bit and 16-bit MCUs with different price / performance ratios. Any single-chip series must provide feasible solutions for embedded system developers to reduce development costs and facilitate faster product introduction to the market. Compatibility of software, peripherals and pins are key factors. In 8-bit mechatronics applications, an 8-bit MCU with 2K bytes of program memory is usually used. If the microcontroller supplier can provide a seamless migration path, allowing 8-bit code to be reused in 16-bit body controller applications (requiring the use of a 100-pin MCU with 256K bytes of program memory), then for ECM manufacturers, this will be Is a great advantage. For example, the PICMCU architecture provides seamless software portability. The architecture that supports a seamless software migration path, combined with compatible pin support, enables developers to quickly bring products to market and keep them in a leading position while meeting budget requirements. Software reuse is an important means to solve the problem of lack of embedded software development resources faced by most ECM vendors. In addition, the PICMCU development tool suite, including the MPLAB integrated development environment, can provide embedded control developers with a cost-effective and seamless development environment, thereby improving developer efficiency. This can shorten the development cycle and reduce development costs. MCU flexibility is very important for automotive ECM developers. In a highly competitive and cost-sensitive market environment, flexibility is an important weapon for survival. In order to meet customer needs, industry requirements, and gain greater market share, automakers are continuously expanding the use of electronic controls. SCM suppliers with high performance and compatible architecture can provide developers with more and more flexible choices in meeting market demands and meeting greater challenges. For ECM suppliers pursuing a competitive advantage, flexibility is even more important in meeting time-to-market requirements and responding more quickly to customer needs.
