No official successor part number is listed. Sourcing is limited to independent distributors carrying new-old-stock or surplus inventory."},{"question":"What is the replacement for CY7C4205-10AXC?","answer":"No official replacement or successor part number is listed in the lifecycle record. A pin-compatible alternative within the CY7C4205 family may exist, but Cypress has not published a direct drop-in. Contact your design team to evaluate a cross if a redesign is feasible."},{"question":"What is the supply voltage of CY7C4205-10AXC?","answer":"The supply voltage range is 4.5 V to 5.5 V, making it a 5 V nominal part. It is not compatible with 3.3 V or lower-voltage logic without level translation."},{"question":"What is the package type of CY7C4205-10AXC?","answer":"The package is a 64-LQFP (low-profile quad flat pack) with a 14x14 mm body, surface-mount. The supplier device package is listed as 64-TQFP (14x14)."},{"question":"What is the access time of CY7C4205-10AXC?","answer":"The access time is 8 ns, measured from the read clock edge to valid data output. At the 100 MHz data rate, this leaves 2 ns of setup margin for the receiving logic."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C4205-10AXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C4205-10AXC when reusing this data.
