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

As most Cypress-chips the CY7C68013A has the ability to be protected from reading-out configuration-data or program-code. I would assume that the manufactor of your camera has done that. Another questionable fact is: if the CY7C68013A is defect, who guarantees that the reading of any data would deliver a useful result.

As most Cypress-chips the CY7C68013A has the ability to be protected...

Probably chip is protected, the same statement I heard

from engineer,  working in local trade office of Cypress.

But because there are only theories, I decide to ask for more details. :)

Another questionable fact is: if the CY7C68013A is defect,

who guarantees that the reading of any data would deliver a useful result.

I have second, full working camera with same PCB revisions, which probably

can be used as source. But when internal code is not readable,

I will think about ordering of spare parts. Solution, at least 3x times expensive. :(

Anyway, thank you for the answer. :)
