基于CY7C68013的存储器测试台的USB通信设计

Design of Communication about the Memory Test Bench Based on CY7C68013

为了对飞行器存储器进行测试,需存储器测试台与飞行器存储器之间完成数据通信。由于USB总线技术具有成本低、数据传输速度快、抗干扰能力强等的优点,这里选用USB总线来完成测试台与存储器之间的通信,用CY7C68013芯片作为USB通信的控制芯片。选用Keilμvision2作为USB通信软件设计的开发环境。通过上位机软件编程来控制测试台CY7C68013与信号源模块,CY7C68013与固态存储器之间的通信。通过对USB通信硬件电路和软件程序的设计,最终完成测试台的USB通信设计。经测试,达到了设计的目的和要求。

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-interference 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.
