Automotive Accurate RTC with Integrated Quartz Crystal

PCA2129 Active
  • This page contains information on a product that is not recommended for new designs.

The PCA2129 is a CMOS 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 PCA2129 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.
