QDR II+ uses separate read and write data ports, each operating at double data rate — so the 450 MHz clock delivers an effective data rate of 900 MHz per port. For a system designer, this means the memory can sustain back-to-back read and write transactions without bus-turnaround dead cycles, which is the defining advantage over common DDR SRAM architectures. The 18-bit word width is a standard data bus for high-end networking and telecom line cards where the memory stores lookup tables or packet buffers. The 165-FBGA package (13x15 mm) has a 1.0 mm ball pitch — a standard four-layer PCB with via-in-pad can fan out the inner rows, but the layout must match the 450 MHz signal integrity requirements for the QDR II+ bus. If your existing BOM uses a different speed grade (e.g. 300 MHz or 400 MHz), the 450 MHz variant is a drop-in replacement on the same PCB layout — no board spin needed. ## Active lifecycle — sourcing posture Infineon lists the CY7C2163KV18-450BZXI as Active (current production). The base product number CY7C2163 covers multiple speed grades and temperature ranges. When ordering, confirm the full suffix — the -450BZXI variant is the 450 MHz industrial-temperature version in a 165-ball FBGA tray.","metaTitle":"Infineon CY7C2163KV18-450BZXI QDR II+ SRAM, 450 MHz","metaDescription":"CY7C2163KV18-450BZXI from Infineon: 18Mbit QDR II+ SRAM, 450 MHz clock, 1Mx18 organization, industrial temp -40°C to 85°C, 165-FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, QDR II+","Memory Size":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Active","Clock Frequency":"450 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C2163","Memory Organization":"1M 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/dcaf9b8936bbac0f6f5ac30d2c485a93.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the memory organization and clock speed of this SRAM?","answer":"The CY7C2163KV18-450BZXI is organized as 1M x 18 bits (18 Mbit total) and operates at a 450 MHz clock frequency.
