Description
Description
The PCA2129 is a CMOS Real Time Clock (RTC) and calendar IC with an integrated Temperature Compensated Crystal Oscillator (TCXO) and a 32.768 kHz quartz crystal. It features a selectable I2C or SPI interface, backup battery switch-over, programmable watchdog, timestamp function, and operates within -40 °C to +85 °C. Typical accuracy is ±3 ppm from -30 °C to +80 °C, with a low supply current of 0.70 μA at 3.3 V.
