Product Summary

The PT7C4363 serial real-time clock is a low-power clock/calendar with a programmable square-wave output. Address and data are transferred serially via a 2-wire bidirectional bus. The PT7C4363 provides seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The PT7C4363 operates in the 24- hour format indicator.

Parametrics

PT7C4363 absolute maximum ratings: (1)Storage Temperature: -65℃ to +150℃; (2)Ambient Temperature with Power Applied: -40℃ to +85℃; (3)Supply Voltage to Ground Potential (Vcc to GND): -0.3V to +6.5V; (4)DC Input (All Other Inputs except Vcc & GND): -0.3V to (Vcc+0.3V); (5)DC Output Voltage (SDA, /INTA, /INTB pins): -0.3V to +6.5V; (6)Power Dissipation: 320mW (depend on package).
