Product Summary

The DP8573AN is a Real Time Clock (RTC). The DP8573AN is intended for using in microprocessor based systems where information is required for multi-tasking, data logging or general time of day/date information. DP8573AN is implemented in low voltage silicon gate microCMOS technology to provide low standby power in battery back-up environments. The architecture of circuit is such that it looks like a contiguous block of memory or I/O ports organized as one block of 32 bytes. This includes the Control Registers, the Clock Counters, the Alarm Compare RAM, and the Time Save RAM.

Parametrics

DP8573AN absolute maximum ratings: (1)Supply Voltage (VCC): -0.5V to +7.0V; (2)DC Input Voltage (VIN): -0.5V to VCC +0.5V; (3)DC Output Voltage (VOUT): -0.5V to VCC +0.5V; (4)Storage Temperature Range: -65℃ to +150℃; (5)Power Dissipation (PD): 500mW; (6)Lead Temperature (Soldering, 10 sec.): 260℃.

Features

DP8573AN features: (1)Full function real time clock/calendar: 12/24 hour mode timekeeping; Day of week counter; Parallel resonant oscillator; (2)Power fail features: Internal power supply switch to external battery; Power Supply Bus glitch protection; Automatic log of time into RAM at power failure; (3)On-chip interrupt structure: Periodic, alarm, and power fail interrupts.
