Abstract: For the need of Charge Coupled Device(CCD) signal acquisition of some payload in spaceflight, a CCD signal acquisition scheme based on USB 2.0 is presented, including the hardware interface design and software design. The hardware architecture is implemented with FPGA and EZ-USB, the USB interface IC is in slave mode and the signal transmission mode is batch transmission. The signal acquisition application is designed on the platform of VC++6.0. The system realizes CCD signal acquisition and runs steady, which is proved with the emulator ISE and Modelsim, and the hardware platform based on EZ-USB

Key words: USB acquisition, Charge Coupled Device(CCD) signal acquisition, firmware, driver
