Renesas Electronics Corporation's 1339AC-31SRGI is a Clock/Calendar Real Time Clock (RTC) IC. This component utilizes an I2C, 2-Wire Serial interface for communication. It features alarm functionality, leap year compensation, and a square wave output. The integrated trickle-charger supports battery backup operation with a voltage range of 1.3V to 3.7V. The main supply voltage operates from 2.7V to 5.5V, with a maximum timekeeping current draw of 200µA at 3.63V to 5.5V. The date format is YY-MM-DD-dd and the time format supports HH:MM:SS (12/24 hr). The 1339AC-31SRGI is housed in a 16-SOIC (0.295", 7.50mm Width) surface mount package and operates across a temperature range of -40°C to 85°C. This device is commonly employed in automotive, industrial, and consumer electronics applications requiring accurate timekeeping.
