Infineon has placed the CY7C1049G18-15ZSXIT in Last Buy status. This is the final purchase window before the part becomes unavailable from the factory. Any open BOM line using this order code needs a last-time-buy quantity commitment or a validated replacement. No official successor order code is listed on the lifecycle record; the replacement path is a pin-compatible density or voltage variant within the CY7C1049 family.","metaTitle":"Infineon CY7C1049G18-15ZSXIT 4Mbit Async SRAM, 15 ns, 44-TSOP II","metaDescription":"Infineon CY7C1049G18-15ZSXIT 4Mbit asynchronous SRAM, 15 ns access time, 1.65V-2.2V supply, -40°C to 85°C.
