PCF2123  
SPI Real time clock/calendar  
Rev. 01 — 19 November 2008  
Product data sheet  
1. General description  
The PCF2123 is a CMOS real time clock and calendar optimized for low power  
applications. Data is transferred serially via a Serial Peripheral Interface bus (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  
I Real time clock provides year, month, day, weekday, hours, minutes and seconds  
based on a 32.768 kHz quartz crystal  
I Low backup current while running: typical 100 nA at VDD = 2.0 V and Tamb = 25 °C  
I Resolution: seconds to years  
I Watchdog functionality  
I Freely programmable timer and alarm with interrupt capability  
I Clock operating voltage: 1.1 V to 5.5 V  
I 3 line SPI-bus with separate combinable data input and output  
I Serial interface at VDD = 1.6 V to 5.5 V  
I 1 second or 1 minute interrupt output  
I Integrated oscillator load capacitors for CL = 7 pF  
I Internal power-on reset  
I Open-drain interrupt and clock output pins  
I Programmable offset register for frequency adjustment  
3. Applications  
I Time keeping application  
I Battery powered devices  
I Metering  
I High duration timers  
I Daily alarms  
I Low standby power applications
