It handles alarm, daylight-savings, and leap-year correction on-chip, and outputs a square wave for system timing. The integrated lithium battery-backed SRAM keeps the time and user data alive when main supply drops to 2.5 V–4 V (battery supply range). ## Supply and keep-alive — dual-rail design Main supply runs 4.5 V to 5.5 V; timekeeping current maxes at 15 mA over that range. When the main rail drops, the battery supply (2.5 V–4 V) takes over to retain the NVSRAM and clock registers. That means no external backup battery management — the module handles the switchover internally. Commercial temperature range (0°C to 70°C) fits indoor equipment, office gear, and appliance controllers, but not an unheated enclosure or engine bay. ## Lifecycle and sourcing — still an active line item The DS12C887+ carries an Active product status and ROHS3 compliance. That means it remains a valid BOM entry for new production runs and legacy sustainment alike.","metaTitle":"DS12C887+ RTC Clock/Calendar, Parallel, 113B NVSRAM, 24-EDIP","metaDescription":"DS12C887+ real-time clock/calendar IC from Analog Devices.
