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.","metaTitle":"1339-31DVGI8 I2C RTC Clock/Calendar, -40°C to 85°C, 8-TSSOP","metaDescription":"1339-31DVGI8 I2C RTC from Renesas.
