CUSTOMER ADVISORY ADV0503 Serial Configuration Device Plating Standardization Change Description: The plating finish of EPCS1SI8 & EPCS4SI8 devices will change to pre-plated NiPdAu. This plating type is an Altera-qualified process and will not affect customer board-mounting processes. This change does not affect form, fit, or function. Reason For Change: Altera would like to standardize on pre-plated NiPdAu finish plating for SOIC package outlines. Products Affected: The devices affected by this transition are EPCS1SI8 and EPCS4SI8. Product Traceability and Transition Dates: Altera will be transitioning the EPCS1SI8 & EPCS4SI8 devices to the pre-plated NiPdAu finish in Q3 of 2005. These devices can be distinguished by the suffix N marked on the top of the devices. For example, the EPCS1SI8 device currently marked as EPCS1 will be marked as EPCS1N.
