Abracon LLC AB1814-T3 is a Real Time Clock (RTC) IC offering clock/calendar functionality with 256B of SRAM. This component utilizes a serial peripheral interface (SPI) for communication and is housed in a 16-VFQFN exposed pad package. Key features include alarms, leap year compensation, a trickle-charger input, and a watchdog timer, contributing to robust timekeeping. The device operates efficiently with a timekeeping current consumption of 0.17µA to 0.22µA across a 1.8V to 3V range. Its voltage supply range is 1.7V to 3.6V, with a battery supply range of 1.5V to 3.6V. The AB1814-T3 supports both HH:MM:SS:hh and YY-MM-DD-dd date formats and is suitable for surface mounting. Operating temperature ranges from -40°C to 85°C. This RTC is commonly employed in industrial control, consumer electronics, and portable device applications. The component is supplied on a Tape & Reel (TR).
