Claims (2)

1. Elektronisches Gerät, insbesondere Feldgerät,
  • 1. mit einem Mikroprozessor (6) zur Ausführung eines An­ wenderprogramms,
  • 2. mit einem Speicher (7), in welchem das Anwenderprogramm abspeicherbar ist,
  • 3. mit einem Speicher (8), in welchen temporäre Daten ab­ speicherbar sind,
  • 4. mit einem nichtflüchtigen Speicher (10), in welchen zu­ mindest ein Teil der temporären Daten zur Sicherung bei einem Spannungsausfall abspeicherbar ist, wobei in einer ersten Phase jeweils ein Datenpaket, eine sogenannte Page, an den nichtflüchtigen Speicher (10) übertragbar ist und der nichtflüchtige Speicher (10) dazu ausgebildet ist, das Datenpaket in einer zweiten Phase selbständig in die zu­ geordneten nichtflüchtigen Speicherzellen abzuspeichern, und
  • 5. mit einem Energiespeicher (15), durch welchen die zur Sicherung der Daten erforderliche Energie nach einem Spannungsausfall bereitstellbar ist,
dadurch gekennzeichnet,
  • 1. daß der Mikroprozessor (6) in einen Energiesparmodus um­ schaltbar ist, in welchem der Energieverbrauch wesentlich geringer als im Normalbetrieb ist, und
  • 2. daß Mittel vorhanden sind, um bei einem Spannungsausfall den Mikroprozessor (6) nach Ablauf der ersten Phase in den Energiesparmodus umzuschalten und um den Mikroprozessor (6) nach Ablauf der zweiten Phase wieder in den Normal­ betrieb zu versetzen.
1. electronic device, in particular field device,
  • 1. with a microprocessor ( 6 ) for executing a user program,
  • 2. with a memory ( 7 ) in which the user program can be stored,
  • 3. with a memory ( 8 ) in which temporary data can be stored,
  • 4. with a non-volatile memory ( 10 ), in which at least some of the temporary data can be stored for backup in the event of a power failure, a data packet, a so-called page, being transferable to the non-volatile memory ( 10 ) in a first phase and the non-volatile memory ( 10 ) is designed to independently store the data packet in a second phase in the assigned non-volatile memory cells, and
  • 5. with an energy store ( 15 ), by means of which the energy required to secure the data can be provided after a power failure,
characterized by
  • 1. that the microprocessor ( 6 ) can be switched to an energy-saving mode in which the energy consumption is substantially less than in normal operation, and
  • 2. that means are available to switch the microprocessor ( 6 ) after the end of the first phase in the energy-saving mode in the event of a power failure and to put the microprocessor ( 6 ) back into normal operation after the end of the second phase.
2. Elektronisches Gerät nach Anspruch 1, dadurch gekenn­ zeichnet, daß ein Zeitgeber (13) vorgesehen ist, der durch den Mikroprozessor (6) nach der ersten Phase gestartet wird und der nach Ablauf einer Zeit, die zumindest größer als die Dauer der zweiten Phase ist, den Mikroprozessor wieder in den Normalbetrieb versetzt.2. Electronic device according to claim 1, characterized in that a timer ( 13 ) is provided, which is started by the microprocessor ( 6 ) after the first phase and after a time which is at least greater than the duration of the second phase is put the microprocessor back into normal operation.
