PROBLEM TO BE SOLVED: To execute a burn-in test at a microcomputer in simple configuration and to generate a stable test pattern. SOLUTION: A microcomputer 101 is composed of a ROM 101a in which a test pattern generating program and a measured data compressing program are stored, a RAM 101b in which measured data are stored while being compressed, CPU 101c for executing the test pattern generating program and measured data compressing program, and an input/output interface circuit 101e for inputting a control signal and outputting the measured data while being connected with an external interface 102 of a burn-in board 100. |
