Single Chip Microcomputer （SCM） course is the core course of electrical-related majors， which is of great value in cultivating students'' innovative ability in engineering practice. However， there are many shortcomings in the current SCM teaching， which leads to the learning outcomes of undergraduates failing to meet the demands of enterprises for engineering innovative talents. In order to solve this problem， this study puts forward a training mode of "whole stage-batch-echelon training" in the School of Innovation and Industrial Engineering of Wanjiang Institute of Technology with the aim of cultivating students'' engineering innovation and practical ability. This method runs through the whole undergraduate stage and pays attention to cross-professional training. After more than 3 years of continuous exploration and practice， the employment rate and postgraduate admission rate of students in pilot majors have been improved. This talent cultivation model has effectively enhanced students'' independent innovation and engineering practice abilities， providing valuable reference for the training of application-oriented talents.
