I'm doing some reliability prediction of electronics equipment by using PRISM. I want to have some information about the category of the components, such as what's the differences between IC and semiconductor, what's the differences among logic IC, analog IC, and digital IC, etc. In addition, given a part number, how could I know which category it is? For example, intel firmware hub 82802AB. Totally no idea. Any resources are very welcome. Thanks.

When performing a reliability prediction it is necessary to determine the types of components that are in the design of the system being analyzed. If you have been provided a Bill of Materials and/or schematic that includes only the part number and vendor for a component, it will be necessary to obtain vendor specifications that define each of these components. Vendor specifications will provide information that will allow you to select the appropriate PRISM reliability prediction model. A good source to identify vendor specifications and part information for integrated circuits and other semiconductor parts (e.g., diodes and transistors) is IC Master (http://icmaster.com/). When I performed a search on 82802AB at this site, it identified that the 82802AB is an integrated circuit (peripheral controller) manufactured by Intel. Based on this information the appropriate PRISM IC model can now be determined. In this case, the model that should be used for the assessment is DIGITAL,CONTROL,PERIPHERAL INTERFACE. If you have any further questions, feel free to contact me. David Dylis Phone: 315-339-7055 Email: ddylis@alionscience.com
