2. Features and benefits

The definition of the abbreviations and acronyms used in this data sheet can be found in

The PCA2129T is a CMOS

Temperature Compensated Crystal (Xtal) Oscillator (TCXO) and a 32.768 kHz quartz

crystal optimized for very high accuracy and very low power consumption. The PCA2129T

has a selectable I

programmable watchdog function, a timestamp function, and many other features.
