RTC with trickle-charger and I²C bus
The Renesas 1339-31DVGI8 is an I²C real-time clock/calendar that tracks time in HH:MM:SS (12/24 hr) and date in YY-MM-DD-dd format. It integrates an alarm, leap-year compensation, a square-wave output, and a trickle-charger for backup-battery management — features that save external components in timekeeping designs for industrial controllers, utility meters, and security panels.
Temperature grade and environment
Rated for -40°C to 85°C, this RTC suits outdoor telecom cabinets, factory-floor automation, and engine-bay-adjacent electronics where the ambient can swing well beyond commercial limits. The 8-TSSOP package (3.00 mm width) is a compact surface-mount footprint that fits dense PCBs without consuming board area.
Lifecycle and sourcing
The 1339-31DVGI8 carries an Active product status with ROHS3 compliance, so there is no near-term end-of-life concern for production planning.
