Real-time Clock Modules
OVERVIEW
The NR8576 Series devices are serial-interface type
real-time clock module ICs with built-in crystal
oscillator elements. They feature timer counter cir-
cuits that keep track of time from the current second
to the current year, automatic leap-year adjustment,
and a supply voltage detect function. Also, a 32.768
kHz/1 Hz select output function is incorporated for
independent hardware control. They are available in
compact 14-pin SOPs (NR8576A
18-pin SOPs (NR8576B
