PCF8563T SOP8 8-bit ADC DAC Real - time Clock Timing IC chip
1. General description
The PCF8563 is a CMOS real-time clock / calendar optimized for low
power consumption.
A programmable clock output, interrupt output and voltage-low
detector are also provided.
All addresses and data are transferred serially via a two-line
bidirectional I2C-bus.
Maximum bus speed is 400 kbit/s. The built-in word address register
is incremented
automatically after each written or read data byte.
2. Features
■ Provides year, month, day, weekday, hours, minutes and seconds
based on 32.768 kHz quartz crystal
■ Century flflag
■ Clock operating voltage: 1.8 V to 5.5 V
■ Low backup current; typical 0.25 µA at VDD = 3.0 V and Tamb = 25
°C
■ 400 kHz two-wire I2C-bus interface (at VDD = 1.8 V to 5.5 V)
■ Programmable clock output for peripheral devices (32.768 kHz,
1024 Hz, 32 Hz and 1 Hz)
■ Alarm and timer functions
■ Integrated oscillator capacitor
■ Internal power-on reset
■ I2C-bus slave address: read A3h and write A2h
■ Open-drain interrupt pin
■ ElectroStatic Discharge (ESD) protection exceeds 2000 V Human
Body Model (HBM) per JESD22-A114,
200 V Machine Model (MM) per JESD22-A115 and 2000 V Charged Device
Model (CDM) per JESD22-C101
■ Latch-up testing is done to JEDEC standard JESD78 which exceeds
100 mA
■ plastic small outline package; 8 leads; body width 3.9 mm
3. Applications
■ Mobile telephones
■ Portable instruments
■ Electronic metering
■ Battery powered products
4.Functional description
The PCF8563 contains sixteen 8-bit registers with an
auto-incrementing address register,
an on-chip 32.768 kHz oscillator with one integrated capacitor, a
frequency divider which
provides the source clock for the Real-Time Clock/calender (RTC), a
programmable clock
output, a timer, an alarm, a voltage-low detector and a 400 kHz
I2C-bus interface.
All 16 registers are designed as addressable 8-bit parallel
registers although not all bits
are implemented. The fifirst two registers (memory address 00h and
01h) are used as
control and/or status registers. The memory addresses 02h through
08h are used as
counters for the clock function (seconds up to years counters).
Address locations 09h
through 0Ch contain alarm registers which defifine the conditions
for an alarm.
Address 0Dh controls the CLKOUT output frequency. 0Eh and 0Fh are
the timer control
and timer registers, respectively.
The seconds, minutes, hours, days, weekdays, months, years as well
as the minute alarm,
hour alarm, day alarm and weekday alarm registers are all coded in
Binary Coded
Decimal (BCD) format.
When one of the RTC registers is read the contents of all counters
are frozen. Therefore,
faulty reading of the clock/calendar during a carry condition is
prevented.
