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.
