PCF85263A  
Tiny Real-Time Clock/calendar with alarm function, battery  
switch-over, time stamp input, and I2C-bus  
Rev. 4.1 — 27 November 2015  
Product data sheet  
1. General description  
The PCF85263A is a CMOS1 Real-Time Clock (RTC) and calendar optimized for low  
power consumption and with automatic switching to battery on main power loss. The RTC  
can also be configured as a stop-watch (elapsed time counter). Three time log registers  
triggered from battery switch-over as well as input driven events. Featuring clock output  
and two independent interrupt signals, two alarms, I2C interface and quartz crystal  
calibration.  
For a selection of NXP Real-Time Clocks, see Table 72 on page 90  
2. Features and benefits  
UL Recognized Component (PCF85263ATL)  
Provides year, month, day, weekday, hours, minutes, seconds and 100th seconds  
based on a 32.768 kHz quartz crystal  
Stop-watch mode for elapsed time counting. From 100th seconds to 999999 hours  
Two independent alarms  
Battery back-up circuit  
WatchDog timer  
Three timestamp registers  
Two independent interrupt generators plus predefined interrupts at every second,  
minute, or hour  
Frequency adjustment via programmable offset register  
Clock operating voltage: 0.9 V to 5.5 V  
Low current; typical 0.28 A at VDD = 3.0 V and Tamb = 25 C  
400 kHz two-line I2C-bus interface (at VDD = 1.8 V to 5.5 V)  
Programmable clock output for peripheral devices (32.768 kHz, 16.384 kHz,  
8.192 kHz, 4.096 kHz, 2.048 kHz, 1.024 kHz, and 1 Hz)  
Configurable oscillator circuit for a wide variety of quartzes: CL = 6 pF, CL = 7 pF, and  
CL = 12.5 pF  
3. Applications  
Printers and copiers  
Electronic metering  
Digital cameras
