PCF85063ATL
Tiny Real-Time Clock/calendar with alarm function and
I2C-bus
Rev. 2 — 15 April 2013
Product data sheet
1. General description
The PCF85063ATL is a CMOS1 Real-Time Clock (RTC) and calendar optimized for low
power consumption. An offset register allows fine-tuning of the clock. All addresses and
data are transferred serially via the two-line bidirectional I2C-bus. Maximum data rate is
400 kbit/s. The register address is incremented automatically after each written or read
data byte.
2. Features and benefits
Provides year, month, day, weekday, hours, minutes, and seconds based on a
32.768 kHz quartz crystal
Clock operating voltage: 0.9 V to 5.5 V
Low current; typical 0.27 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)
Selectable integrated oscillator load capacitors for CL = 7 pF or CL = 12.5 pF
Alarm function

Countdown timer
Minute and half minute interrupt
Internal Power-On Reset (POR)
Programmable offset register for frequency adjustment
3. Applications
Digital still camera
Digital video camera
Printers
Copy machines
Mobile equipment
Battery powered devices

Tiny Real-Time Clock/calendar with alarm function and I2C-bus
8. Functional description
The PCF85063ATL contains 18 8-bit registers with an auto-incrementing register address,
an on-chip 32.768 kHz oscillator with integrated capacitors, a frequency divider which
provides the source clock for the Real-Time Clock (RTC) and calender, and an I2C-bus
interface with a maximum data rate of 400 kbit/s.
The built-in address register will increment automatically after each read or write of a data
byte up to the register 11h. After register 11h, the auto-incrementing will wrap around to
address 00h (see Figure 3).

Fig 3. Handling address registers
All registers (see Table 5) are designed as addressable 8-bit parallel registers although
not all bits are implemented. The first two registers (memory address 00h and 01h) are
http://www.DataSheet4U.net/
used as control and status register. The register at address 02h is an offset register
allowing the fine-tuning of the clock; and at 03h is a free RAM byte. The addresses 04h
through 0Ah are used as counters for the clock function (seconds up to years counters).
Address locations 0Bh through 0Fh contain alarm registers which define the conditions for
an alarm. The registers at 10h and 11h are for the timer function.
The Seconds, Minutes, Hours, Days, Months, and Years as well as the corresponding
alarm registers are all coded in Binary Coded Decimal (BCD) format. When one of the
RTC registers is written or read, the contents of all time counters are frozen. Therefore,
faulty writing or reading of the clock and calendar during a carry condition is prevented.
For details on maximum access time, see Section 8.4 on page 22.

Tiny Real-Time Clock/calendar with alarm function and I2C-bus
From a stop condition, the first 1 second increment will take place after 32 positive edges
on pin CLKOUT. Thereafter, every 64 positive edges cause a 1 second increment.
Remark: Entry into test mode is not synchronized to the internal 64 Hz clock. When
entering the test mode, no assumption as to the state of the prescaler can be made.
Operation example:
1. Set EXT_TEST test mode (register Control_1, bit EXT_TEST = 1).
2. Set STOP (register Control_1, bit STOP = 1).
3. Clear STOP (register Control_1, bit STOP = 0).
4. Set time registers to desired value.
5. Apply 32 clock pulses to pin CLKOUT.
6. Read time registers to see the first change.
7. Apply 64 clock pulses to pin CLKOUT.
8. Read time registers to see the second change.
Repeat 7 and 8 for additional increments.
8.2.1.2 STOP: STOP bit function
The function of the STOP bit (see Figure 4) is to allow for accurate starting of the time
circuits. The STOP bit function causes the upper part of the prescaler (F2 to F14) to be
held in reset and thus no 1 Hz ticks are generated. It also stops the output of clock
frequencies below 8 kHz on pin CLKOUT.

The time circuits can then be set and do not increment until the STOP bit is released (see
Figure 5 and Table 7).
