Abstract: For warranty reasons it is desirable to count certain events such as power cycles, operating time, hard (pushbutton) resets, and timeouts. Although digital counters are easy to build, it is not that obvious how to make them nonvolatile and nonresettable. This article explains how to use the EPROM-emulation mode of readily available serial EEPROMs together with an unusual coding scheme to solve the problem.Maxim > Design support > App notes > 1-Wire Devices > APP 5042 Maxim > Design support > App notes > Memory > APP 5042 Keywords: digital counter, nonvolatile, nonresettable, NV, EPROM emulation mode, EEPROM, EPROM, eeprom, eprom Jun 08, 2011 APPLICATION NOTE 5042 Implementing Nonvolatile, Nonresettable Counters for Embedded Systems By: Bernhard Linke, Principal Member Technical Staff Abstract: For warranty reasons it is desirable to count certain events such as power cycles, operating time, hard (pushbutton) resets, and timeouts.
