PROBLEM TO BE SOLVED: To provide a data communication system, a semiconductor device and a data communication method, capable of information data transmission through a communication interface having a specified response period, without reduction of operation efficiency.SOLUTION: When a first controller included in a first information processing device transmits a request signal requesting to execute predetermined data processing, a first communication interface unit included in the first information processing device makes a pseudo response to the first controller according to one request signal, and transmits the request signal to the second information processing device side. The second information processing device replies the first information processing device side with a result as response data. At this time, the first communication interface unit in the first information processing device stores the received response data into a memory, and according to a request signal issued for the second time and after from the first controller, reads out the response data from the memory to supply to the first controller. |
