Features
| Counters for tenths/hundredths of seconds, seconds, minutes, hours, day, date, month, year, and century |
| 32 KHz crystal oscillator with integrated load capacitance (12.5 pf) which provides exceptional oscillator stability and high crystal series resistance operation) |
| Oscillator stop detection (monitors clock operation) |
| Serial interface supports I2C bus (400 kHz protocol) |
| Ultra-low battery supply current of 0.6 μA (typ) |
| 2.0 to 5.5 V clock operating voltage |
| Automatic switchover and deselect circuitry (fixed reference) which provides full operation in 3.0 V applications) |
| VCC= 2.7 to 5.5 V |
| 2.5 V ≤ VPFD≤ 2.7 V |
| Power-down time-stamp (HT bit) which allows determination of time elapsed in battery backup |
| Battery low flag |
| Programmable alarm and interrupt function (valid even during battery backup mode) |
| Accurate programmable watchdog timer (from 62.5 ms to 128 s) |
| Software clock calibration (to compensate for crystal deviation due to temperature) |
| Operating temperature of –40 to 85 °C |
| Package options include an 8-lead SOIC or 18-lead embedded crystal SOIC |
