PCF2129AT  
Integrated RTC, TCXO and quartz crystal  
Rev. 6 — 11 July 2013  
Product data sheet  
1. General description  
The PCF2129AT 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  
PCF2129AT 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.  
2. Features and benefits  
Temperature Compensated Crystal Oscillator (TCXO) with integrated capacitors  
Typical accuracy: 3 ppm from 15 C to +60 C  
Integration of a 32.768 kHz quartz crystal and oscillator in the same package  
Provides year, month, day, weekday, hours, minutes, seconds, and leap year  
correction  
Timestamp function  
with interrupt capability  
detection of two different events on one multilevel input pin (for example, for tamper  
detection)  
Two line bidirectional 400 kHz Fast-mode I2C-bus interface  
3 line SPI-bus with separate data input and output (maximum speed 6.5 Mbit/s)  
Battery backup input pin and switch-over circuitry  
Battery backed output voltage pin  
Battery low detection function  
Extra power fail detection function with input and output pins  
Power-On Reset Override (PORO)  
Oscillator stop detection function  
Interrupt output (open-drain)  
Programmable 1 second or 1 minute interrupt  
Programmable watchdog timer with interrupt  
Programmable alarm function with interrupt capability  
Programmable square wave open-drain output pin  
Clock operating voltage: 1.2 V to 4.2 V  
Low supply current: typical 0.65 A at VDD = 3.0 V
