The utility model discloses an integrated development system for a single-chip microcomputer, and the system comprises a simulation single-chip microcomputer and a development single-chip microcomputer, which are connected with each other and are integrate on one PCB. The PCB comprises a JTAG external interface which is connected with the simulation single-chip microcomputer. The simulation single-chip microcomputer is connected with the development single-chip microcomputer through a short-circuit cap, thereby achieving the functional switching of the JTAG external interface and the development single-chip microcomputer. The integrated design of the system enables the simulation single-chip microcomputer and the development single-chip microcomputer to be installed on the same PCB, enables the success rate of the communication of a development board with a computer to be improved, and enables the cost of the system to be reduced. The multiplexing function of the JTAG external interface on the development board can be connected or disconnected through the short circuit cap, thereby facilitating the application of the single-chip microcomputers on the development board and helping a user develop a single-chip microcomputer by himself or herself.
