NXP USA Inc. presents the PCF2129AT-1-518, a Clock/Calendar IC designed for precise timekeeping. This component utilizes an I2C, 2-Wire Serial interface for efficient communication and is housed in a 20-SOIC package, measuring 7.50mm in width. Key features include alarm functionality, leap year compensation, square wave output, and a watchdog timer, all supported by an integrated TCXO/crystal for enhanced accuracy. The device operates within a supply voltage range of 1.8V to 4.2V, with a remarkably low timekeeping current consumption of 1.5µA at 3.3V. It supports both 12/24 hour and YY-MM-DD-dd date formats. This Real Time Clock IC is commonly employed in industrial automation, automotive systems, and consumer electronics applications requiring robust timekeeping capabilities. The PCF2129AT-1-518 is supplied on Tape & Reel (TR).
