The 44-pin SOJ package (0.400\" body width) is a common footprint for 256K x 16 SRAMs, making it a candidate for board-level repair or retrofit into existing sockets. ## What the 12 ns access time means for your bus For a 66 MHz bus with a 15 ns clock period, this SRAM leaves about 3 ns of margin after address setup and hold — tight but workable with good PCB layout. If your system runs above 66 MHz or has long trace delays, you may need a pipelined or synchronous SRAM instead. For those, look for the -12VXI variant (industrial temp, also obsolete) or a current-production industrial-grade part.","metaTitle":"CY7C1041BNV33L-12VXCT SRAM, 4Mbit, 12 ns, 44-SOJ","metaDescription":"Infineon CY7C1041BNV33L-12VXCT asynchronous SRAM, 4Mbit (256K x 16), 12 ns access time, 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":"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-BSOJ (0.400\\\", 10.16mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C1041","Memory Organization":"256K x 16","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"44-SOJ","Write Cycle Time - Word, Page":"12ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0a6d676fc26529c37bc07ebf3b8d401f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C1041BNV33L-12VXCT?","answer":"For a new design, consider a current-production asynchronous SRAM in the same 256K x 16, 44-SOJ footprint, such as parts from the Infineon CY7C1041G series or equivalent from other vendors — but verify pin compatibility, timing, and supply voltage before substituting.

They are pin-compatible and functionally identical, so the -12VXI can serve as a drop-in replacement if the temperature range fits your application."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1041BNV33L-12VXCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1041BNV33L-12VXCT when reusing this data.
