The 44-pin TSOP II package (0.400-inch body, 10.16 mm height) is a standard footprint for this density class; it reflows with a standard profile and is hand-solderable with a fine tip if you are careful. ## 15 ns access — timing margin for a 50–66 MHz bus On a 50 MHz bus (20 ns cycle), that leaves about 5 ns of margin after accounting for address-to-chip-enable and output-enable delays — tight but workable if the PCB trace lengths are kept under 3 inches and the load capacitance is reasonable. At 66 MHz (15 ns cycle), you are cycle-bound; the part still works if the controller inserts one wait state. ## Industrial temperature, active lifecycle If you are dual-sourcing, the base part number CY7C1041 covers the family; the G18 suffix indicates the 1.8 V supply variant and the -15ZSXI speed/package/temperature code.","metaTitle":"Infineon CY7C1041G18-15ZSXI 4Mbit Async SRAM, 15 ns","metaDescription":"Infineon CY7C1041G18-15ZSXI 4Mbit (256K x 16) asynchronous SRAM, 15 ns access time, parallel interface, 1.65V–2.2V supply, -40°C to 85°C, 44-TSOP II.","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 - Asynchronous","Access Time":"15 ns","Memory Size":"4Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"44-TSOP (0.400\\\", 10.16mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.65V ~ 2.2V","Base Product Number":"CY7C1041","Memory Organization":"256K x 16","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"44-TSOP II","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.7662","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4b583d433046ca582816ac98334bd436.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1041G18-15ZSXI/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1041G18-15ZSXI RoHS compliant?","answer":"The part number suffix 'XI' indicates a lead-free, RoHS-compliant finish.
