It clocks at 550 MHz on the parallel interface. At 550 MHz, the QDR II+ interface eliminates the dead cycles between read and write turns that older NoBL or DDR SRAMs leave on the table. ## Lifecycle reality — EOL phase, plan the last buy The CY7C1263KV18-550BZXC carries an EOL-hot lifecycle stage. That means Infineon has notified the end-of-life — the last-time-buy window is either open or closing. For a BOM that depends on this exact density and speed grade, the procurement move is to secure final-order quantities now rather than chase dwindling surplus later.","metaTitle":"Infineon CY7C1263KV18-550BZXC 36Mbit QDR II+ SRAM, 550 MHz","metaDescription":"Infineon CY7C1263KV18-550BZXC synchronous SRAM, 36Mbit organized 2M x 18, 550 MHz clock, 1.7V-1.9V supply, 165-FBGA, commercial temp.

The last-time-buy window is active or closing — secure final quantities through an RFQ rather than assuming ongoing production availability."},{"question":"What is the direct replacement for CY7C1263KV18-550BZXC?","answer":"No official successor order code is listed in the lifecycle record for this exact 36Mbit, 550 MHz, 165-FBGA variant. A pin-compatible drop-in from the same QDR II+ family is not confirmed. For a like-for-like replacement, a cross-reference search against the 36Mbit QDR II+ portfolio is the next step, but the safest procurement path is a last-time-buy of this part number."},{"question":"What is the operating voltage range for CY7C1263KV18?","answer":"The supply voltage range is 1.7V to 1.9V, which is the standard core rail for 1.8V-class QDR II+ SRAMs. The parallel interface operates at the same voltage, so the FPGA or ASIC port must match this I/O level."},{"question":"What is CY7C1263KV18-550BZXC's listed technology?","answer":"It is a synchronous SRAM using QDR II+ (Quad Data Rate II+) architecture, organized as 2M words by 18 bits for a total of 36Mbit. The QDR II+ interface allows simultaneous read and write on separate ports, eliminating bus-turnaround dead cycles."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1263KV18-550BZXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1263KV18-550BZXC when reusing this data.
