■ 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 .
