The Renesas Electronics Corporation X1227S8I-2-7AT2 is a Clock/Calendar IC designed for precise timekeeping applications. This component utilizes a 2-wire serial interface, commonly known as I2C, for efficient communication. It features an 8-SOIC package with a 0.154" (3.90mm) width, suitable for surface mounting. The X1227S8I-2-7AT2 operates across a voltage range of 2.7V to 5.5V, with a battery backup input voltage range of 1.8V to 5.5V. At 2.7V, its timekeeping current consumption is typically between 10µA and 20µA. Key features include alarm functionality, leap year compensation, a supervisor function, and a watchdog timer, enhancing system reliability. The date format is YY-MM-DD-dd, and the time format supports both 12 and 24-hour modes (HH:MM:SS). This device is frequently employed in industrial automation, consumer electronics, and automotive systems requiring accurate temporal data. The X1227S8I-2-7AT2 is supplied in a Tape & Reel (TR) package.
