In the context of new engineering, international talents are required to possess interdisciplinary abilities while also possessing a patriotic craftsmanship spirit. In response to the problem, the existing microcontroller teaching system cannot meet the new requirements of international talents in the context of new engineering, and foreign languages are disconnected from professional abilities. Through literature research, this article identifies the problems of unclear teaching objectives, lack of close connection with ideological and political education, lagging and incomplete teaching content, poor matching with professional foreign languages, and outdated assessment and evaluation systems in existing microcontroller courses. Based on this, to solve temporary problems, it is proposed to integrate three abilities and pay equal attention to teaching objectives, embed ideological and political education and foreign language education content The teaching method of “classroom extracurricular” and “professional ability foreign language ability” is a double seamless connection, with a diversified evaluation system and a multi resource shared teaching team construction idea. This teaching reform aims to cultivate interdisciplinary talents with the integration of “professional+foreign language+ideological and political”, and is expected to effectively improve the matching degree between single-chip microcomputer courses and the cultivation of international talents in new engineering. This has provided new ideas for the cultivation of international talents in the context of new engineering, and promoted the development of contemporary single-chip teaching reform.
