Details
The DP8573A is intended for use in microprocessor based systems where information is required for multi-tasking, data logging or general time of day/date information. This device is implemented in low voltage silicon gate microCMOS technology to provide low standby power in battery back-up environments. Time and date are maintained from 1/100 of a second to year and leap year in a BCD format, 12 or 24 hour modes. Day of week and day of month counters are provided. Time is controlled by an on-chip crystal oscillator requiring only the addition of the 32.768 kHz crystal and two capacitors.
