The Renesas Electronics Corporation 1339B-31DVGI8 is a Clock/Calendar IC designed for precise timekeeping applications. This component facilitates accurate clock and calendar functions, supporting both HH:MM:SS (12/24 hr) and YY-MM-DD-dd date formats. Its serial interface utilizes the I2C protocol for efficient communication. Key features include alarm functionality, leap year compensation, and a square wave output, along with integrated trickle-charger capabilities for battery backup. The device operates within a voltage range of 2.7V to 5.5V for the main supply and 1.3V to 3.7V for battery backup, with a timekeeping current consumption of up to 200µA at 3.63V to 5.5V. Supplied in an 8-TSSOP package, the 1339B-31DVGI8 is suitable for surface mount installation and operates across an industrial temperature range of -40°C to 85°C. This timekeeping solution finds application in various sectors including industrial automation, consumer electronics, and telecommunications.
