Real-Time Clock Device, Impact Logger, And Electronic Apparatus

Abstract

A real-time clock device includes a clocking circuit that generates time information, a memory circuit, a processing circuit that records impact log information based on a plurality of pieces of acceleration data and the time information in a retention period of an impact log in the memory circuit when it is determined that an impact event has occurred based on an acceleration detected by an acceleration sensor, and an interface circuit that outputs the impact log information recorded in the memory circuit.
