Real-time clock/calendar

The PCA8565A is a CMOS Real-Time Clock (RTC) and calendar optimized for lowpower consumption. A programmable clock output, interrupt output, and voltage-lowdetector are also provided. All addresses and data are transferred serially via a two-linebidirectional I2C-bus. Maximum bus speed is 400 kbit/s \n? AEC-Q100 compliant for automotive applications\n? Provides year, month, day, weekday, hours, minutes, and seconds based on32.768 kHz quartz crystal\n? Clock operating voltage: 1.8 V to 5.5 V\n? Extended operating temperature range: -40 °C to +125 °C\n? Low backup current: typical 0.65 μA at VDD ;
