It integrates 114 bytes of nonvolatile SRAM, so configuration data survives a main power loss without an external EEPROM. On-chip features include alarm, daylight savings adjustment, leap-year compensation, and a square-wave output for driving a periodic interrupt or blinking an indicator. The 24-SOIC wide-body package (0.295-inch body width, 7.50 mm) is a standard footprint that reflows cleanly and is straightforward to inspect or rework under a hot-air station — no hidden pads, no micro-BGA challenges.","metaTitle":"DS12885SN+ RTC Clock/Calendar, Parallel, 114B NVSRAM","metaDescription":"Maxim DS12885SN+ real-time clock/calendar with parallel interface, 114B NVSRAM, alarm, daylight savings. 4.5V-5.5V supply, 2.5V-4V battery backup.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Clock/Calendar","Package":"Tube","Features":"Alarm, Daylight Savings, Leap Year, NVSRAM, Square Wave Output","Interface":"Parallel","Date Format":"YY-MM-DD-dd","Memory Size":"114B","Time Format":"HH:MM:SS (12/24 hr)","Mounting Type":"Surface Mount","Package / Case":"24-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"24-SOIC","Voltage - Supply, Battery":"2.5V ~ 4V","Current - Timekeeping (Max)":"15mA @ 4.5V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.11","priceTiers":[{"qty":1,"price":"$11.11000","currency":"USD"},{"qty":10,"price":"$10.03200","currency":"USD"},{"qty":25,"price":"$9.56560","currency":"USD"},{"qty":100,"price":"$8.30580","currency":"USD"},{"qty":250,"price":"$7.93256","currency":"USD"},{"qty":500,"price":"$7.23260","currency":"USD"},{"qty":1000,"price":"$6.29937","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DS12885SN%2B/alternatives.json"},"ai":{"faq":[{"question":"What is the interface of the DS12885SN+?","answer":"It uses a parallel interface — address and data lines are multiplexed on the same bus, compatible with most 8-bit microcontrollers and processors."},{"question":"How long does the battery last in DS12885SN+?","answer":"Battery life depends on the cell capacity and the timekeeping current, which is up to 15 mA when the main supply is present. In battery-backup mode the current is lower — typical lithium coin cells can retain time and NVSRAM for years, but exact duration depends on the cell rating and ambient temperature. The datasheet provides the backup-current specification for your calculation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/DS12885SN~3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/DS12885SN~3 when reusing this data.
