Abstract
Programmable on-chip identification circuitry and associated method are disclosed that provide integrated circuits with the ability to select and report from multiple different vendor and system identification configurations. The integrated circuit device includes programmable circuitry that utilizes vendor identification, system identification, configuration or other device information provided or selected at least in part based upon selection information from a source external to the integrated circuit. The selection information may be provided through one or more externally generated digital and/or analog control signals that are then processed within the integrated circuit device to select, access and utilize desired identification information stored in an on-chip database. For example, one or more analog control signals can be generated using resistor circuits for which specific selectable resistor configurations map to particular information stored in a look-up table or other database structure within the integrated circuit. The analog control signals are converted to digital values within the integrated circuit, and these digital values are used to select device information …
