In order to fully test the aircraft memory,it’s needed to complete data communication between memory test bench and aircraft memory. USB bus technology has the advantage of cost,speed of data transmission,anti-inter-ference ability and so on,so it is selected to complete the communication between the memory and the test bench. CY7C68013 chip is selected as the USB communication control chip. Keil μvision2 is selected as USB communication software design development environment. The communication between the test bench CY7C68013 and signal source module, CY7C68013 and solid state memory is controlled by PC software program. The final completion of the USB communication design of the test bench includes the design of USB hardware circuit and software program. It achieves the purpose and requirements of the design on test.
