NR8576 Series NIPPON PRECISION CIRCUITS INC. 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 32.768 kHz/1 Hz select output function is incorporated for independent hardware control. They are available in compact 14-pin SOPs (NR8576A×) and miniature 18-pin SOPs (NR8576B×).
