What is the difference between MDA/MWA and MDC/MWC?
Die products are categorized into two levels of quality assurance. The first category is identified and ordered by the suffix identifier MDA (die) and MWA (wafer). MDA and MWA die products are warranted to the standard package product electrical specifications and reliability levels. The second category is identified and ordered by the suffix identifier MDC (die) and MWC (wafer). MDC and MWC die products have an equivalent reliability assurance as MDA and MWA die products but due to restrictions in die level processing are not guaranteed to be equivalent to the standard packaged product electrical specifications. MDC and MWC products are offered with a conditional performance guarantee to the standard product electrical specifications. Minimal yield impact to the application is expected but characterization of MDC and MWC die products by the user in their application is recommended. All National die products are 100% tested at the wafer level and are manufactured using our established,
