The data processor with access protection which has higher reliability during data transfer control according to a transfer condition set by a CPU. The data processor has: a CPU; a memory management section operable to control data transfer by the CPU; and a transfer controller operable to control the data transfer. The transfer controller holds identification information which the memory management section uses for access protection. When producing an address for transfer according to the setting of the CPU, the transfer controller starts data transfer on the condition that the identification information corresponding to the address for transfer matches the identification information of the CPU at the setting of a transfer condition, etc.
