PCF85263A Real-Time Clock (RTC) & Calendar

NXP Semiconductors PCF85263A Real-Time Clock (RTC) and Calendar is optimized for low power consumption with automatic switching to battery on main power loss. The PCF85263A 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. The PCF85263A features a clock output and two independent interrupt signals, two alarms, an I2C interface, and quartz crystal calibration.
