  • Builtin crystal unit allows adjustment-free efficient operation.
  • 8-bit data bus and high speed access (85 nsec. max.).
  • Provided with the same interface as S-RAM and battery backup function.
  • Interruption of alarm of sec. to day and day of week and carry interruption.
  • Reference signal selectable in a range of 1 Hz to 64 Hz (binary).
  • Leap year automatically adjustable (gregorian calendar).
  • With 1 Hz output terminal.
  • Provided with START/STOP, 30 second adjust function.
  • RTC-64613 uses a similar mounting method to that of a normal SMD IC.
