No AEC-Q100 qualification is listed, so this is an industrial/commercial part, not automotive. Infineon lists the CY7C1565V18-400BZI as Obsolete. That means the factory last-time buy window has closed; new production is not coming. Sourcing now goes through independent distribution — broker channel, surplus stock, or customer inventory resale. Date codes will vary, and counterfeit screening (X-ray, decap, electrical test) is a standard gate before committing a production batch. The 165-FBGA package is not trivial to rework, so verify the die markings match Infineon's known-good devices.","metaTitle":"CY7C1565V18-400BZI QDR II SRAM, 72Mbit, 400 MHz, Obsolete","metaDescription":"Infineon CY7C1565V18-400BZI is a 72Mbit QDR II synchronous SRAM, 400 MHz clock, 2M x 36 organization, -40 to 85°C, 165-FBGA.","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":"Tray","Technology":"SRAM - Synchronous, QDR II","Memory Size":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"400 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1565","Memory Organization":"2M x 36","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"165-FBGA (15x17)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c282ea8f3288590b277ec0782040cb33.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C1565V18-400BZI obsolete?","answer":"Yes, Infineon lists the CY7C1565V18-400BZI as Obsolete.
