Abstract: One kind of USB connection module based on the FPGA+CY7C68013 and its application in servo system were introduced, hardware plans about basing USB2.0 interface chip CY7C68013 synchronized SlaveFIFO read-write mode on the foundation and the field programmable gate array(FPGA) regarded as the state control chip were discussed. By establishing the firmware program and the verilog procedure , with the interface of USB2.0,servo driver and PC have successfully realized high speeding transmission. Finally,the Cypress USB Console of the superior machine software was used to test, result shows that the system has the merits that the data transmission is accurate and quick.
