NR8576 series

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 circuits 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 32.768kHz/1Hz select out-

put function is incorporated for independent hardware control. They are available in compact 14-pin SOPs

(NR8576A×) and miniature 18-pin SOPs (NR8576B×).

FEATURES

^ꢀCrystal oscillator element built-in for adjustment-
