Abstract
An integrated circuit comprises a microprocessor (1), a memory (2) and one or more internal peripherals (3) connected, firstly, to one another and, secondly, to circuits external (4) to this integrated circuit by means of connections circuits (5). The peripherals comprise circuits called options circuits (6) enabling the operation of these peripherals to be configured. For an operating session corresponding to putting of the integrated circuit into service, the operations of these peripherals are defined as a function of information elements stored in the the first part of the memory (7). The memory also has a second part (8) designed to store instructions that can be executed by the microcontroller. This configuration of the peripherals takes place when the integrated circuit is put into service, by the linking of said peripherals to said first part of the memory. This memory is of the programmable type. The circuits known as options circuits possess means for being configured by default for a particular mode of operation of the microprocessor of the integrated circuit called the programming mode. In this mode, this microprocessor is capable of writing in the first part of the memory.
