Abracon LLC AB1804-T3 is a highly accurate Real Time Clock (RTC) IC designed for robust timekeeping applications. This Clock/Calendar component features a 256B SRAM for data storage, and its timekeeping current consumption is remarkably low, ranging from 0.17µA to 0.22µA across its 1.8V to 3V operating voltage range. The AB1804-T3 supports both YY-MM-DD-dd and HH:MM:SS:hh date and time formats, respectively. Key features include alarm functionality, leap year compensation, trickle-charger support for battery backup, and an integrated watchdog timer for system reliability. Communication is facilitated via an I2C, 2-Wire Serial interface. The device is housed in a compact 16-VFQFN Exposed Pad package, suitable for surface mounting, and is supplied on tape and reel for automated assembly. This component is commonly employed in industrial control, consumer electronics, and telecommunications equipment.
