In a nonvolatile memory writing device that writes writing data transmitted from the microcomputer to a nonvolatile memory provided outside the microcomputer, the nonvolatile memory is a nonvolatile memory in which writing is protected and the protection is disabled by an electric signal from the microcomputer to the write-protect terminal of the nonvolatile memory, the write-protect terminal is connected to the power supply of the microcomputer, and when the electric signal from the microcomputer to the write-protect terminal is interrupted, the protection is disabled, even when the data is interrupted due to a change in the power supply voltage, it is possible to prevent garbled date due to the write protection signal during the write period of the write data.
