The device includes a trickle-charger for charging a backup battery or supercapacitor, and automatically handles leap-year corrections through 2099. ## Battery-backup and supply considerations A separate battery-supply pin accepts 1.3 V to 3.7 V, allowing a 3 V lithium coin cell or a 2.5 V supercap to keep timekeeping alive when the main rail drops. The trickle-charger feature means the backup capacitor can be recharged on the board — useful in designs where the battery is not user-replaceable and the product must survive years of intermittent power.","metaTitle":"DS1340Z-3+ RTC Clock/Calendar, I²C, 8-SOIC, -40 to 85°C","metaDescription":"Analog Devices DS1340Z-3+ RTC with I²C interface, 2.7-5.5V supply, trickle-charger, 125µA timekeeping.
