Infineon lists the CY7C1041D-10VXIT as obsolete. ## Package and storage — 44-SOJ on Tape & Reel The 44-SOJ package is a 10.16 mm wide, 0.400 inch body, J-bend lead form. The Tape & Reel shipping medium means the parts arrive on a reel.","metaTitle":"Infineon CY7C1041D-10VXIT 4Mbit Async SRAM, 10 ns, 44-SOJ","metaDescription":"Infineon CY7C1041D-10VXIT 4Mbit asynchronous SRAM, 10 ns access time, 256K x 16 organization, 4.5V-5.5V supply, -40°C to 85°C.","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":"10 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":"4.5V ~ 5.5V","Base Product Number":"CY7C1041","Memory Organization":"256K x 16","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"44-SOJ","Write Cycle Time - Word, Page":"10ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8f377cf6cf393b9309e28994c75873b8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to CY7C1041D-10VXIT?","answer":"No official pin-compatible replacement is listed by Infineon.
