• Factory programmable output frequency: 1Hz to 32.768kHz

• Available in two types of ultra-miniature packages:

2.0 x 1.2 x 0.6mm (SMD); 1.54 x 0.84 x 0.6mm (CSP)

• Supply Voltage: 1.2V to 3.63V (-10 ~ +70°C); 1.5V to 3.63V (-40 ~ +85°C)

• Ultra-Low Current Consumption: 1.4µA max. (core current, no load)

• Frequency Stabilities include:

±75ppm over -10 to +70°C, ±100ppm over -40 to +85°C

• Internal power supply filtering eliminates external bypass capacitor for Vdd port.

• Proprietary NanoDriveTM Technology by SiTime enables programmable output swing

for lower power

• Timekeeping
