DescriptionThe DP8573AV is one member of the DP8573A family which is designed as the Real Time Clock (RTC). This device is implemented in low voltage silicon gate microCMOS technology to provide low standby power in battery back-up environments. And the circuit's architecture is such that it looks like a contiguous block of memory or I/O ports organized as one block of 32 bytes.
Features of the DP8573AV are:(1)full function real time clock/calendar:12/24 hour mode timekeeping, day of week counter and 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.
The absolute maximum ratings of the DP8573AV can be summarized as:(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):500 mW;(6)lead temperature (soldering, 10 sec.):260.
