Technical Details & Description

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.

The 8-TSSOP package (3.00 mm width) is a compact surface-mount footprint that fits dense PCBs without consuming board area.

Frequently asked questions

Does 1339-31DVGI8 have a trickle charger feature?

Yes, it includes a trickle-charger for maintaining a backup battery or supercapacitor during main power loss.

What is the current consumption of 1339-31DVGI8?

Timekeeping current is 200µA maximum when powered from 3.63V to 5.5V.

Can 1339-31DVGI8 replace DS1307?

Both are I²C RTCs with similar basic functions, but the 1339-31DVGI8 adds a trickle-charger and operates down to -40°C versus the DS1307's commercial range. Pin compatibility should be verified against the respective datasheets before substitution.
