NR8576中文资料Real-time Clock Modules数据手册NPC规格书

描述 Description

The NR8576 series 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 output function is incorporated for independent hardware control.
