Description
The PCF2128 is a ready to run CMOS real time clock/calendar with an integrated temperature compensated crystal oscillator (TCXO).
In timekeeping applications the high accuracy of the PCF2128 allows it to be used as a replacement for costly and higher powered long wave receivers or GPS receivers.
Features
- 512 bytes of general purpose RAM, a programmable watchdog, a time stamp facility and a voltage monitoring facility. Programming is possible using either an SPI or an I2C-bus interface. 2. Features.
- Integration of a 32.768 kHz quartz crystal in the same package as the RTC.
- temperature compensated crystal oscillator (TCXO) with integrated capacitors.
- accuracy: typically 3 ppm from.
- 20 °C to +70 °C, typically 5 ppm from.
- 40 °C to +85 °C.
- provides.
