PCA8565
Real time clock/calendar
Rev. 4 — 5 December 2014
Product data sheet
1. General description
The PCA8565 is a CMOS1 real time clock and calendar optimized for low power
consumption. A programmable clock output, interrupt output and voltage-low detector are
also provided. All address 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.
For a selection of NXP Real-Time Clocks, see Table 36 on page 40
2. Features and benefits
AEC-Q100 compliant (PCA8565TS) for automotive applications
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 at room temperature
Extended operating temperature range: 40 C to +125 C
Low current; typical 0.65 A 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, 1.024 kHz, 32 Hz and
1 Hz)
Alarm and timer functions
Internal power-on reset
I2C-bus slave address: read A3h and write A2h
Open-drain interrupt pin
One integrated oscillator capacitor
3. Applications
Automotive
Industrial
Other applications that require a wide operating temperature range
