It sits between the system supply, a backup battery, and the SRAM, automatically switching to battery power when the main rail drops below the threshold. The controller also monitors the battery voltage and asserts a warning flag if the battery is low. This is the part you reach for when a legacy SRAM-backed design needs a clean power-fail handoff without a separate supervisor IC. ## 3.3V supply — the fit question answered Supply range is 3V to 3.6V, so it operates on a 3.3V rail. The battery monitor threshold is set internally for a lithium cell. ## Temperature grade and environment Rated for -40°C to 85°C, so it fits industrial environments — factory automation, outdoor telecom cabinets, engine-bay-adjacent control modules, and any unheated enclosure. The 8-SOIC package is easy to hand-solder in a rework station or even with a fine-tip iron if the board is accessible. No hot-air station required for a field swap, which matters when the repair is on site. ## Lifecycle and sourcing reality The DS1314S-2+ is listed as Active and ROHS3 compliant. No end-of-life notice, no last-time-buy pressure. It is a current-production part from Maxim (now part of Analog Devices). For a BOM line that needs a nonvolatile RAM controller with battery monitoring, this is a stable, available choice — no need to qualify a substitute unless you want a second source for supply resilience.","metaTitle":"DS1314S-2+ Nonvolatile RAM Controller, 3V-3.6V, 8-SOIC","metaDescription":"Maxim DS1314S-2+ nonvolatile RAM controller with battery monitor. 3V to 3.6V supply, -40°C to 85°C, 8-SOIC.
