It uses Maxim's NVSRAM technology, which stores the SRAM contents to an internal EEPROM array on power-down and restores them on power-up — no battery, no external supervisor, no lithium cell to replace or dispose of. The 150 ns access time and 150 ns write cycle time match the bus timing of many 8-bit microcontrollers and legacy CPLD-based memory interfaces. The industrial temperature range (-40°C to 85°C) suits it for outdoor telecom cabinets, factory-floor controllers, and engine-bay data loggers where battery-backed SRAM would drift out of spec or leak. ## 150 ns access — bus timing fit Access time is 150 ns; write cycle time is also 150 ns. ## Industrial temperature and supply range Rated for -40°C to 85°C ambient. Supply range is 4.5 V to 5.5 V. ## Lifecycle and sourcing The DS1225AD-150IND+ carries an Active lifecycle status from the manufacturer and is ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect.","metaTitle":"DS1225AD-150IND+ NVSRAM, 64Kbit, 150 ns, Industrial Temp","metaDescription":"Maxim DS1225AD-150IND+ NVSRAM: 64Kbit (8K x 8), 150 ns access, parallel interface, -40°C to 85°C, 28-EDIP.

Within the DS1225AD family, density and speed variants exist, but the DS1225AD-150IND+ is the industrial-temperature 150 ns version. For a pin-compatible alternative, check the DS1225AB series (same footprint, faster access) or the DS1230 series (higher density, different pinout).
