A method is disclosed for programming an ID register of a microchip. The method comprises the step, prior to packaging, of attaching at least one additional ID pin to the die of the microchip. The at least one pin being so attached that, when the microchip is packaged, the at least one pin is sealed within the package. At least a portion of the microchip identity data is programmed by providing a plurality of unique combinations of binary data to the at least one additional pin. Each unique combination of binary data corresponds to a unique identity of the microchip. The at least one pin is coupled to a respective module of the microchip layout for providing, via the at least one pin, information associated with the particular identity of the microchip. The at least one pin is also coupled to the identification register, so as to, upon testing, include the respective combination of binary data in the ID register data of the microchip.
