According to the characteristics of linear CCD drive timing, a design method of linear CCD driver circuit is given. A MCU with enhanced core is adopted to generate CCD needed drive pulse, which gives full play to programmable technical feature of the MCU and provides ample drive signal interface and the electronic shutter function is realized. Firstly, it is introduced about basic working principle, main features and timing drive design ideas of the MCU with enhanced core. Secondly, the software and hardware of the drive module are designed using above design ideas. Lastly, a lot of experiments are done to verify the effectiveness of the driving module, the test results show that the module can stably generate driving pulse that can meet the needs of linear CCD entirely. When integrated into other measurement systems, the measurement systems can work normally and stably. And it has a higher measuring accuracy.
