怎么使用CY7C68013A-56PVXC修复USB摄像机

您好，我有一个问题，USB摄像头，使用芯片CY7C68013A 56PVXC：
相机没有响应，当连接到PC & GT时，我替换了XTAL -没有变化。我在PCB上没有看到损坏的部件或轨道。1V8和2V8测试点的电压是可以的。相机的显示器为我提供更换PCB，但我想先尝试修理。我有一台第二台工作摄像机，硬件完全一样。是否有可能购买新的芯片CY7C68013A 56PVXC，PCB上的焊料，并从工作摄像机复制固件代码？在CY7C68013A—56PVXC中是否存在复制保护，这将防止固件从一个芯片复制到另一个芯片？提前感谢！瓦伦丁

  Hello,

I have a problem with USB video camera, that uses chip CY7C68013A-56PVXC :
     
     
   

> Camera not responding, when are connected to the PC.
> I replaced a XTAL - no change.
> I don't see broken components or tracks on PCB.
> Voltages of 1V8 & 2V8 test points are OK.
> Manifacturer of camera offer me replacement PCB, but I want to try repair first.

I have a second, working camera with exactly the same hardware.

> Is it possible to buy new chip CY7C68013A-56PVXC,
solder on PCB and copy firmware code from working camera?

> Is it exist copy protection in CY7C68013A-56PVXC,
that will prevent duplicating of firmware from one chip to another ?

Thanks in advance!
Valentin
