I am not sure if this is the most appropriate forum but as my question is related to the PSOC 4200, I thought I would start here.
We have a product that uses the CY8C4245PVI-482.
We are about to contract out assembly of 1000 of our product
What I want to do is supply the contract company a pre-programmed controller. Each must have a serial number.
1) Is there a service that can perform production programming (or do you know if we can purchase from Cypress pre-programmed with our firmware)
2) Does the device have a unique serial number built-in we could use or would we need to have the firmware somehow serialized ? We do not care what the numbers are as long as we can derive unquiqe value between 1 and 65535.
In other products we use the Dallas serial number IC but we have no room or pins available on the board for this.
If I recall correctly PSOC 3 and 5LP have a silicon ID that dives down to the
wafer level. Not unique, only to the row on the wafer unique.
You might file a CASE to get the silicon ID (4 bytes) makeup, specifially
point out what you are trying to do.
To create a technical or issue case at Cypress -
“Create a Case”
You have to be registered on Cypress web site first.
I should have explained a little better.
Those I found in PSOC 5LP Register TRM. So thought is
if you file a CASE maybe the equivalents are in the PSOC 4 ?
It's a longshot, but worth a try.
