The EPSON RX-8581NB-B3-PURE-SN is a Real Time Clock (RTC) IC featuring clock and calendar functionality with an I2C, 2-Wire Serial interface. This component, part of the RX-8581NB series, is supplied in a 22-SON (5x6) package, specifically a 22-LFDFN. Its capabilities include alarm functions and leap year compensation, with a date format of YY-MM-DD-dd and a 24-hour time format of HH:MM:SS. The device operates across a voltage supply range of 1.8V to 5.5V and exhibits a low timekeeping current consumption of 0.8µA to 1.2µA at 3V to 5V. Designed for surface mount applications, it operates within an industrial temperature range of -40°C to 85°C. This RTC is commonly utilized in industrial automation, consumer electronics, and automotive systems requiring accurate timekeeping. The RX-8581NB-B3-PURE-SN is provided in Tape & Reel (TR) packaging.
