Product Details

General description       

• The PCA8565 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 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.

  Features           

• Provides year, month, day, weekday, hours, minutes and seconds based on 32.768 kHz quartz crystal

• Century flag

• Clock operating voltage: 1.8 to 5.5 V

• Extended operating temperature range:−40 to +125°C

• Low backup current; typical 0.5µA at VDD= 3.0 V and Tamb=25°C

• 400 kHz two-wire I2C-bus interface (at VDD= 1.8 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.

Applications

• Automotive

• Industrial

• Other applications that require a wide operating temperature range.
