General description

The PCF2129 is a CMOS1 Real Time Clock (RTC) and calendar with an integrated

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

crystal optimized for very high accuracy and very low power consumption. The PCF2129

has a selectable I2C-bus or SPI-bus, a backup battery switch-over circuit, a

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

For a selection of NXP Real-Time Clocks, see Table 83 on page 75
