Abstract: An integrated circuit (122) includes an on-chip boot ROM (132) holding boot code, a non-volatile security identification element (140) having non-volatile information determining a less secure type or more secure type, and a processor (130). The processor (130) is coupled to the on-chip boot ROM (132) and to the non-volatile security identification element (140) to selectively execute boot code depending on the non-volatile information of the non-volatile security identification element (140). Other technology such as processors, methods of operation, processes of manufacture, wireless communications apparatus, and wireless handsets are also disclosed.
