Product Overview
The PCF2129T/2,518 is an accurate RTC with an integrated temperature compensated crystal (Xtal) oscillator (TCXO) and a 32.768kHz quartz crystal optimized for very high accuracy and very low power consumption. This has a selectable I²C-bus or SPI-bus, a backup battery switch-over circuit, a programmable watchdog function and a timestamp function.
- Timestamp function with interrupt capability
- 3 Line SPI-bus with separate data input and output
- Battery backup input pin and switch-over circuitry
- Oscillator stop detection function
- Open-drain interrupt output
- Programmable watchdog timer with interrupt
