It tracks time in HH:MM:SS (24-hour format) and date in YY-MM-DD-dd format, with leap-year compensation built in. The battery-backup input accepts 1.3V to 3.7V, keeping the RTC running during main power loss. Maximum timekeeping current is 100µA at 1.89V, which sets the battery-life floor in a backup scenario. The trickle-charger feature recharges a supercap or lithium coin cell through a programmable series resistor. The tube delivery suits prototype and low-volume builds; reel options are available through the supply chain. ## Lifecycle and compliance status Analog Devices lists the DS1340Z-18+ as Active with ROHS3 compliance.","metaTitle":"DS1340Z-18+ RTC, I²C Clock/Calendar, 8-SOIC, Active","metaDescription":"DS1340Z-18+ I²C RTC from Analog Devices.
