There is no LTB window remaining — the part is already discontinued from the factory. ## 44-SOJ package — rework and footprint notes The 44-SOJ (Small Outline J-lead) package is a surface-mount form factor with J-bend leads on a 0.400-inch body width. It is a legacy package that reworks reasonably well with hot air — the J-leads are visible for inspection and touch-up, unlike a QFN or BGA. The SOJ footprint is specific to this memory family; verify the land pattern against your board layout.","metaTitle":"CY7C1021CV33-15VXC SRAM 1Mbit 15 ns Asynchronous, 44-SOJ","metaDescription":"Infineon CY7C1021CV33-15VXC 1Mbit asynchronous SRAM, 64K x 16, 15 ns access, 3V-3.6V, 44-SOJ.","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":"Tube","Technology":"SRAM - Asynchronous","Access Time":"15 ns","Memory Size":"1Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"44-BSOJ (0.400\\\", 10.16mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C1021","Memory Organization":"64K x 16","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"44-SOJ","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cb9e43c6aaaaaca4c2680a604607fb10.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1021CV33-15VXC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1021CV33-15VXC obsolete and what are the alternatives?","answer":"Yes, the CY7C1021CV33-15VXC is obsolete per Infineon's lifecycle status. No official replacement part is listed. For a drop-in alternative, the CY7C1021CV33-15VI shares the same 44-SOJ package and 15 ns speed grade but is also obsolete. A pin-compatible alternative within the same family is the CY7C1021CV33-15ZI, which uses a 44-TSOP-II package — not a direct footprint match. Evaluate the board's mechanical constraints before substituting."},{"question":"What is the lead time for CY7C1021CV33-15VXC?","answer":"As an obsolete part, there is no factory lead time.
