Abracon LLC's AB0803-T3 is a Real Time Clock (RTC) IC featuring a clock/calendar function with 64 bytes of SRAM. This component utilizes an I2C and 2-Wire serial interface for communication. The AB0803-T3 supports both YY-MM-DD-dd date format and HH:MM:SS:hh time format, with features including alarm functionality, leap year calculation, and a trickle-charger input. Operating within a voltage range of 1.7V to 3.6V for the main supply and 1.5V to 3.6V for battery backup, it maintains timekeeping with a low current draw of 0.17µA to 0.22µA at 1.8V to 3V. The device is housed in a 16-VFQFN exposed pad package, suitable for surface mounting, and is supplied on tape and reel. This RTC is commonly employed in automotive, industrial, and consumer electronics applications demanding accurate timekeeping.
