The QDR II+ interface delivers independent read and write data ports on every clock edge, eliminating bus-turnaround dead cycles that limit conventional SRAM throughput in packet-processing and line-card applications. Infineon has classified the CY7C2565KV18-400BZXI as Obsolete. No direct replacement or successor part is listed in the product line. For BOM positions still requiring this exact order code, procurement must source from the open market through independent distributors. The 0.65 mm ball pitch demands a multi-layer PCB with controlled-impedance routing; the layout engineer should verify escape-routing feasibility early in the design cycle. ## Industrial temperature and package constraints The 1.7V–1.9V supply rail is tighter than standard 1.8V ±5%; the power supply must be regulated to stay within this window, especially under load transients from the 400 MHz clock. The 165-ball FBGA (13x15 mm) package requires a 4-layer or more PCB for fan-out. Decoupling capacitors should be placed within 2 mm of the BGA balls on the bottom layer; the 0.65 mm pitch limits the via size to 0.25 mm finished diameter.","metaTitle":"CY7C2565KV18-400BZXI 72Mbit QDR II+ SRAM – Obsolete, 400 MHz","metaDescription":"Infineon CY7C2565KV18-400BZXI 72Mbit synchronous QDR II+ SRAM, 400 MHz clock, 2M x 36 organization, industrial temp, 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":"CY7C2565","Memory Organization":"2M x 36","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3c7a85af978faf32db1ae5248c170d35.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C2565KV18-400BZXI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C2565KV18-400BZXI when reusing this data.
