Communication is over a standard I²C bus, and the part integrates an alarm, leap-year compensation, and a watchdog timer. ## Supply, power, and temperature range The main supply range spans 0.9 V to 5.5 V, with a separate battery-backup input accepting the same 0.9 V to 5.5 V range. Timekeeping current draw is a maximum of 0.885 µA at 3.3 V, making it suitable for battery-powered or always-on applications where quiescent drain matters. Housed in a 12-bump WLCSP (wafer-level chip-scale package) measuring 1.19 mm x 0.94 mm, the PCF85263AUKZ demands a fine-pitch PCB layout with careful solder-paste stencil design for the 0.4 mm ball pitch.","metaTitle":"PCF85263AUKZ RTC Clock/Calendar, I²C, WLCSP, Active","metaDescription":"NXP PCF85263AUKZ RTC/Calendar IC, I²C interface, 0.885µA timekeeping at 3.3V, 0.9-5.5V supply, WLCSP-12.
