Infineon lists this part as Obsolete. Sourcing is through surplus or broker channels. A replacement must match the 44-SOJ footprint and 5V supply. ## 44-SOJ footprint — what to check on the board The package is a 44-lead SOJ (Small Outline J-lead), 0.400\" body width, 10.16 mm. If you're trying to fit a replacement, the J-lead pitch and body width are the dimensions that matter — not the Tape & Reel shipping format.","metaTitle":"CY7C1021BNL-15VXCT Infineon 1Mbit Async SRAM, 15 ns, 44-SOJ","metaDescription":"CY7C1021BNL-15VXCT Infineon 1Mbit (64K x 16) asynchronous SRAM with 15 ns access time, 4.5V-5.5V supply, 44-SOJ package.","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":"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":"4.5V ~ 5.5V","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":"$2.6800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b005a36e8e3c18743572ba4643b8046f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1021BNL-15VXCT/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1021BNL-15VXCT obsolete?","answer":"Yes, Infineon lists this part as Obsolete."},{"question":"What is the access time of CY7C1021BNL-15VXCT?","answer":"The access time is 15 ns, which is the maximum time from address change to valid data output."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1021BNL-15VXCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1021BNL-15VXCT when reusing this data.
