DP8573AN Description

Short technical summary and product information.

The DP8573AN from Texas Instruments is a full-function real-time clock and calendar IC designed for microprocessor-based systems requiring time-of-day and date information. Implemented in low-voltage microCMOS technology, it offers low standby power for battery-backed applications.

 

This device supports both 12 and 24-hour timekeeping modes, maintaining time from 1/100 of a second up to the year, including leap year calculations, in BCD format. It features day-of-week and day-of-month counters. The clock is controlled by an on-chip crystal oscillator, requiring an external 32.768 kHz crystal and two capacitors. Power failure logic is integrated, allowing for automatic logging of time into RAM when the main supply voltage drops below the battery supply voltage.

 

The DP8573AN provides three interrupt types: Periodic, Alarm/Compare, and Power Fail. It operates with a supply voltage range of 2.2V to 5.1V and has a typical operating current of 1µA at 5V. The operating temperature range is -40°C to 85°C.

 

Packaged in a 24-DIP through-hole configuration, the DP8573AN is suitable for applications needing reliable timekeeping, data logging, and multi-tasking support.
