PCF85263A

Tiny Real-Time Clock/calendar with alarm function, battery

switch-over, time stamp input, and I2C-bus

Rev. 5 — 1 February 2021

Product data sheet

1 General description

The PCF85263A is a CMOS 1 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-bus interface and

quartz crystal calibration.

For a selection of NXP Real-Time Clocks, see Table 71

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 999 999 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 μA 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

• Packages offered: SI8, TSSOP8, TSSOP10, HXSON10 and WLCSP12
