INTEGRATED CIRCUIT DEVICE, OSCILLATION DEVICE, AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an integrated circuit device that makes an exclusive terminal for high voltage unnecessary and is capable of performing writing into a nonvolatile memory without increasing a size and costs, an oscillation device, and an electronic apparatus.SOLUTION: An electronic apparatus includes: a power terminal P1 that receives a plurality of voltages including a first voltage different from ground voltage and a second voltage higher than the first voltage; a nonvolatile storage part 10 that writes data when the power terminal receives the second voltage and performs processing other than the data writing when the power terminal receives the first voltage; and a first circuit (a regulator 3) that performs regular operation when the power terminal receives the first voltage and is different from the nonvolatile storage part.
