General description
The PCF85263A is a CMOS1 Real-Time Clock (RTC) and calendar optimized for low power consumption and with automatic switching to battery on main power loss. The RTC can also be configured as a stop-watch (elapsed time counter). Three time log registers triggered from battery switch-over as well as input driven events. Featuring clock output and two independent interrupt signals, two alarms, I2C interface and quartz crystal calibration.For a selection of NXP Real-Time Clocks, see Table 72 on page 90
