An integrated circuit has an integrated circuit core formed with an application core circuit portion, a code generating circuit portion for generating a customer-specific code assigned to the integrated circuit, a proprietary code provider portion adapted to be set by the customer for providing a proprietary code, and a matching circuit portion having inputs connected to the code generating circuit portion and the proprietary code provider portion to receive the customer-specific code and the proprietary code therefrom, and an output connected to the application core circuit portion. The matching circuit portion asserts the application core circuit portion upon detection of a match between the customer-specific code and the proprietary code. A plurality of application bonding pads and code setting bonding pads are provided on the integrated circuit core. The application bonding pads are connected to the application core circuit portion and the proprietary code provider portion. The code setting bonding pads are connected to the code generating circuit portion, and are programmed by selectively connecting each of the code setting bonding pads to a reference potential to enable the code generating circuit portion to generate the customer-specific code assigned to the integrated circuit.
