<p>A method and apparatus for tracking and identifying printed circuit assemblies (101-105, 121-128) is presented. Information about each printed circuit assembly (PCA) (101-105, 121-128), including the current revision level of the PCA is stored within a non-volatile random access memory (RAM) (617) within each PCA. The stored information may be accessed by a user through a dedicated bus (100) and hardware designed for this task. Additionally, through the dedicated bus (100) and hardware, the user may update the information within the printed circuit assembly.</p> |
