Question:

I have Cypress Flash devices that have been in storage for an extended amount of time. What should I do to ensure that the parts would work in my application? 

 

Answer:

When inspecting Flash devices that have been stored for extended periods of time, examination of the vacuum sealed bag and humidity Indicator card must first be done to determine if moisture has penetrated the barrier bag. Additionally, preliminary testing such as solder-ability and a limited trial run with the old material is recommended. The "Long Term Storage Of Packaged Semiconductor IC Product" application note may provide additional helpful information:
