Question:

What is the content value of Factory and Customer SSR for the S29VS-Rxx?

 

Answer:

For Factory SSR, the content value should be either all FFFF's or contain a specific Electronic Serial Number (ESN) and customer code requested by the end customer. The Factory then sets the protection to prevent cloning of the contents programmed within the SSR. For Customer SSR, the content value should also be all FFFF's. However, the SSR is left unprotected to allow the user to program whatever data he/she wishes. No random bytes should be programmed within the Customer SSR. If there are random bytes programmed, these specific device may be return goods from a previous customer. Please contact the Cypress-authorized distributor from whom the S29VS-Rxx devices were purchased. All address locations within the Factory SSR and Customer SSR are programmed only once. No Erase operation is possible.
