A cross-reference search for a pin-compatible 4 Mbit asynchronous SRAM in 44-TSOP II with a 20 ns or faster access time is the practical path; verify the access-time grade against your bus timing before substituting."},{"question":"What are the specifications of CY7C1041BN-20ZSXA?","answer":"It is a 4 Mbit asynchronous SRAM organized as 256K x 16 bits, with a 20 ns access time, parallel interface, 4.5 V to 5.5 V supply, and -40°C to 85°C operating temperature. It comes in a 44-TSOP II package."},{"question":"What is the difference between CY7C1041BN-20ZSXA and CY7C1041BN-15ZSXA?","answer":"The difference is the access time: the -20ZSXA is rated at 20 ns, while the -15ZSXA is rated at 15 ns. The 5 ns difference matters for bus timing — the -20ZSXA will not meet a timing budget designed for 15 ns parts."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1041BN-20ZSXA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1041BN-20ZSXA when reusing this data.
