A 12 ns access time means the SRAM can complete a read cycle within one clock edge of a 66 MHz bus without wait states, or two edges of a 100 MHz bus. For a 3.3V asynchronous interface, that timing gives the memory controller a clean setup-and-hold window, especially important when the SRAM shares a bus with a NOR Flash or a peripheral FPGA that also runs at similar speed. ## Industrial temperature grade and environment The 44-TSOP II package (0.400\" body width, 10.16 mm) is a standard surface-mount footprint that reflows with conventional lead-free profiles and is straightforward to inspect and rework. Infineon lists the CY7C1049CV33-12ZSXAT as obsolete. For BOM lines that still need this exact part — legacy production runs, field-service spares, or qualification-locked designs — the supply channel is independent distribution and surplus inventory.","metaTitle":"Infineon CY7C1049CV33-12ZSXAT 4Mbit Async SRAM, 12 ns","metaDescription":"Infineon CY7C1049CV33-12ZSXAT 4Mbit asynchronous SRAM, 12 ns access time, 3V-3.6V supply, -40°C to 85°C, 44-TSOP II.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Technology":"SRAM - Asynchronous","Access Time":"12 ns","Memory Size":"4Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"44-TSOP (0.400\\\", 10.16mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C1049","Memory Organization":"512K x 8","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"44-TSOP II","Write Cycle Time - Word, Page":"12ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/21ee4ab087c9aeda792a0fd4564f6526.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C1049CV33-12ZSXAT obsolete?","answer":"Yes, Infineon has marked the CY7C1049CV33-12ZSXAT as obsolete.
