Infineon has moved this part to last-time-buy status, so new orders are fulfilled from remaining stock or surplus channel inventory. No direct successor order code is listed."},{"question":"Can CY7C1663KV18-550BZXC replace an older QDR part?","answer":"Yes, the QDR II+ architecture is backward-compatible with QDR II interfaces at the protocol level, but the 550 MHz clock rate is significantly faster than typical QDR II parts. Verify that the memory controller supports the higher frequency and the 1.7V-1.9V supply range before substituting."},{"question":"What is the difference between QDR and QDR II+ SRAM?","answer":"QDR II+ doubles the data rate compared to QDR II by using a higher clock frequency and improved I/O timing. The CY7C1663KV18-550BZXC runs at 550 MHz, whereas typical QDR II parts top out around 250-333 MHz. Both use separate read and write ports, but QDR II+ tightens setup/hold windows for the faster edge rate."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1663KV18-550BZXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1663KV18-550BZXC when reusing this data.
