It operates from a 4.5 V to 5.5 V supply and delivers a 15 ns access time. The 15 ns access time is the headline timing spec. It means the SRAM can complete a read or write cycle in 15 ns. This part is marked obsolete. For BOM lines that need this exact order code, supply runs through the independent surplus and broker channel. This limits the part to indoor, climate-controlled equipment. The 44-SOJ package (0.400\" body width, 10.16 mm) is a JEDEC-standard SOJ footprint. It is surface-mount, so no through-hole adapter needed.","metaTitle":"Infineon CY7C1021BN-15VXC 1Mbit SRAM, 15 ns, 44-SOJ","metaDescription":"Infineon CY7C1021BN-15VXC 1Mbit asynchronous SRAM, 64K x 16, 15 ns access, 4.5-5.5 V, 0°C-70°C, 44-SOJ.

The closest pin-compatible alternative within the same family is the CY7C1021BN-15VXI, which shares the same 44-SOJ package and 15 ns access time but is rated for the industrial temperature range (-40°C to 85°C).
