Technical Examples

Programs or data in a mask ROM incorporated in a one-chip microcomputer can be modified from the outside. With version information appended to each of a mask ROM 2 incorporated in a one-chip microcomputer 6 and an external EPROM 5, by comparing the version numbers, programs (tasks and subroutines) of a new version can always be executed and update data of a new version can be used. The programs can be customized for each user.
