PCF2113DU/2/F4,026

Display Drivers Overview

The PCF2113DU/2/F4,026 is a CMOS Real-Time Clock (RTC) and calendar featuring an integrated temperature-compensated crystal oscillator (TCXO) and a 32.768 kHz quartz crystal. It supports I²C bus and SPI bus interfaces for flexible microcontroller integration. The device includes a backup battery input with switching circuitry to maintain timekeeping during main power loss. It provides comprehensive calendar functions tracking year, month, day, weekday, hour, minute, second, and 1/100th of a second, including leap-year correction. The component operates within a clock voltage range of 1.2 V to 5.5 V and offers high timing accuracy across extended temperature ranges.
