Echtzeituhr
Eine Echtzeituhr wird primär verwendet, damit ein digitales System relativ zur menschlichen Wahrnehmung kontinuierlich die Zeit messen kann. Üblicherweise laufen sie sehr viel langsamer und verbrauchen weniger Strom als herkömmliche Uhren. Der Stromverbrauch ist bei einer Echtzeituhr häufig der wichtigste Aspekt, da sie in der Regel über längere Zeiträume mit einer kleinen tragbaren Stromversorgung (z. B. einer Knopfzelle oder einem Superkondensator) betrieben werden muss, wenn der Rest des Systems abgeschaltet ist. Echtzeituhren sind auch mit erweiterten Funktionen zur Kalibrierung und zur Temperaturkompensation, mit Alarmfunktionen, Timern, Energiemanagementfunktionen sowie mit integriertem Speicher verfügbar.
