This paper describes the design of CCD camera that is part of the EUV detector to be used in Space Solar Telescope. It will run at the solar synchronous circular orbit with 735 km height. In this paper, a CCD camera is designed composed of the CCD sensor module, the analog system and the embedded controller with an NIOSII soft-core processor based on FPGA. The analog system is first introduced in detail including power and bias voltage supply circuit, 16 bit A/D converter, power protecting circuit, amplifier circuit, and CCD driving clocks generation circuit. NIOS II embedded system is then presented including system hardware and NIOS II processor. Finally, evaluation results of this camera are also presented including readout noise, gain, linearity, dynamic range and full well capacity.
