Controller for use in motor vehicle engine, has integrated circuits including firmly programmed identification information, and programmable memory containing control information, which checks identification information

摘要

The controller (10) has an integrated circuit (1) with a microcontroller (3) and a programmable memory (4) e.g. flash memory. Other integrated circuits (2, 7) include firmly programmed identification information (6). The memory contains control information, which checks the identification information. The memory is protected against reprogramming by irreversible blowing of securing a sub-area, in which the control information is stored.
