INTEGRATED CIRCUIT DEVICE WITH TAMPER DTECTION INPUT AND HAVING REAL TIME CLOCK AND CALENDAR LOGGING THEREOF

摘要

If an enclosure of a metering device is opened or vandalized, application software must determine when the metering history information became unreliable, and further notification to the utility may be desirable. Likewise, a shipping container or suitcase that has been opened or mishandled during shipping transient may be attributed to a particular location and/or handling person(s) when the time and date of the mishandling occurrence are known. An input from a tamper or mishandling sensor (120) initiates capture of real¬ time clock/calendar (RTCC) information.
