With the rapid development of industries such as mobile intelligence and the Internet of Things, there is an increasing demand for high precision and intelligence. In order to enable customers to complete system development faster and more conveniently, some sensor manufacturers have begun to provide more advanced modular development platforms, namely MCU sensors, to enhance their information processing capabilities. This has gradually become a new technological trend. However, MCU sensors require more complex mixed signal manufacturing processes. It is necessary to carefully observe where this development trend can go in the future and how Chinese companies can adapt to this trend.
