<p>PROBLEM TO BE SOLVED: To prevent the damage of a CPU(Central Processing Unit) due to a high voltage signal to be input to an ASIC(Application Specific Integrated Circuit) when a program is written in the case of mounting the ASIC and the CPU on the same substrate.SOLUTION: The electronic equipment includes: a substrate; an ASIC mounted on the substrate for performing predetermined processing to a signal to be input from the outside, and for outputting it, and for, when a program is written, inputting a signal from the outside; a CPU mounted on the substrate for executing processing on the basis of a signal to be input from the ASIC; and protection means for, when the program is written in the ASIC, blocking the signal to be input from the outside to the ASIC from intruding via wiring on the substrate into the CPU, or for suppressing the voltage of the signal which intrudes into the CPU.</p> |
