PCF2123  
SPI Real time clock/calendar  
Rev. 6 — 15 July 2013  
Product data sheet  
1. General description  
The PCF2123 is a CMOS1 Real-Time Clock (RTC) and calendar optimized for low power  
applications. Data is transferred serially via a Serial Peripheral Interface (SPI-bus) with a  
maximum data rate of 6.25 Mbit/s. An alarm and timer function is also available providing  
the possibility to generate a wake-up signal on an interrupt pin. An offset register allows  
fine tuning of the clock.  
2. Features and benefits  
Real time clock provides year, month, day, weekday, hours, minutes, and seconds  
based on a 32.768 kHz quartz crystal  
Low backup current while running: typical 100 nA at VDD = 2.0 V and Tamb = 25 C  
Resolution: seconds to years  
Watchdog functionality  
Freely programmable timer and alarm with interrupt capability  
Clock operating voltage: 1.1 V to 5.5 V  
3 line SPI-bus with separate, but combinable data input and output  
Serial interface at VDD = 1.8 V to 5.5 V  
1 second or 1 minute interrupt output  
Integrated oscillator load capacitors for CL = 7 pF  
Internal Power-On Reset (POR)  
Open-drain interrupt and clock output pins  
Programmable offset register for frequency adjustment  
3. Applications  
Time keeping application  
Battery powered devices  
Metering  
High duration timers  
Daily alarms  
Low standby power applications
