          The bq4845 Real-Time Clock is a low-power microprocessor peripheral that integrates a time-of-day clock, a 100-year calendar, and a CPU supervisor in a 28-pin SOIC or DIP. The bq4845 is ideal for fax machines, copiers, industrial control systems, point-of-sale terminals, data loggers, and computers. ? Real-Time Clock counts seconds through years in BCD format\n? On-chip battery-backup switchover circuit with nonvolatile control for external SRAM\n? Less than 500nA of clock operation current in backup mode\n? Microprocessor reset valid to VCC =VSS\n? Independent watchdog timer with a programmabl;
