It combines the fast read/write cycle of a standard SRAM with internal lithium energy cells that preserve data when the supply drops — no external battery or controller needed. The part is housed in a 24-pin EDIP (0.600-inch, 15.24 mm pitch) and operates from a 4.5 V to 5.5 V supply over the commercial temperature range of 0°C to 70°C. ## 120 ns access time — timing for legacy buses The 120 ns access time sets the window for the processor to read or write data. The write cycle time is also 120 ns. ## NVSRAM vs battery-backed SRAM — no battery replacement Unlike conventional battery-backed SRAM modules that use a replaceable coin cell, the DS1220AD-120+ integrates non-volatile elements that store data without a user-serviceable battery. The internal lithium cells are sealed and rated for the life of the product. This eliminates scheduled battery swaps and the risk of data loss from a depleted cell. ## Active lifecycle — no LTB risk The DS1220AD-120+ carries an Active product status. There is no last-time-buy or NRND flag, so it remains available for both new designs and production replenishment. The part is also ROHS3 compliant.","metaTitle":"DS1220AD-120+ NVSRAM, 16Kbit, 120 ns, Parallel, 24-EDIP","metaDescription":"Maxim Integrated DS1220AD-120+ NVSRAM: 16Kbit, 120 ns access time, parallel interface, 4.5V-5.5V supply, 0°C-70°C, 24-EDIP.
