Abracon LLC AB0804-T3 is a Real Time Clock (RTC) IC featuring a Clock/Calendar function with 256 bytes of integrated SRAM. This component utilizes an I2C, 2-Wire Serial interface for communication and is housed in a 16-VFQFN Exposed Pad package, supplied on tape and reel. Key features include alarm functionality, leap year compensation, and a trickle-charger circuit. Additionally, it incorporates a watchdog timer for enhanced system reliability. The AB0804-T3 operates within a voltage range of 1.7V to 3.6V for the main supply and 1.5V to 3.6V for battery backup. Timekeeping current consumption is remarkably low, ranging from 0.17µA to 0.22µA at 1.8V to 3V. This device is suitable for surface mount applications and operates across a temperature range of -40°C to 85°C. Its precise timing capabilities and integrated features make it a valuable component in industrial automation, consumer electronics, and communication systems. The date format is YY-MM-DD-dd, and the time format is HH:MM:SS:hh.
