At 550 MHz the QDR II+ interface delivers a peak data rate of 1.1 G transfers per second per I/O pin (double-data-rate on both read and write ports). The 18-bit-wide data bus yields a theoretical bandwidth of 19.8 Gbit/s. In practice, signal-integrity margin on the 165-ball FBGA layout — trace length matching, on-die termination, and decoupling at the 1.7V–1.9V core supply — determines whether that rate closes timing in a real board. ## Obsolete — last-time-buy and sourcing reality Infineon (formerly Cypress) has discontinued this density and speed grade in the QDR II+ family. If a form-fit-function replacement is needed, a cross-reference search against other 36Mbit QDR II+ SRAMs in the 165-FBGA footprint is the next step, but no pin-compatible alternate is documented here.","metaTitle":"Infineon CY7C1263KV18-550BZI QDR II+ SRAM, 36Mbit, 550 MHz","metaDescription":"Infineon CY7C1263KV18-550BZI is a 36Mbit QDR II+ synchronous SRAM with 550 MHz clock, 2M x 18 organization, 1.7V–1.9V supply, industrial temp.","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":"36Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"550 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1263","Memory Organization":"2M x 18","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/277b6dff6a1b6061a2b90de843d6cc80.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1263KV18-550BZI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1263KV18-550BZI when reusing this data.
