The 10 ns cycle time means the memory can keep pace with a 100 MHz bus without wait states, provided the controller's output hold time and setup budget are met. ## 48-TFBGA footprint and rework considerations The 48-TFBGA package (7x8.5 mm body, 0.5 mm ball pitch) demands careful PCB layout and rework discipline. For the PCB layout engineer: route the 16-bit data bus and address lines with matched trace lengths to avoid skew on the 10 ns window; place decoupling capacitors within 2 mm of the BGA ball field — a 0.1 µF ceramic per supply pin pair, plus a 4.7 µF bulk cap near the package edge. Hot-air rework stations need a bottom-side preheat to 100°C to prevent cold joints on the inner balls. For the procurement buyer, this removes the single-source risk flag that obsolete SRAMs carry — you can qualify this part into a new BOM without planning a future respin. The base product number CY7C1041 covers a family of density and speed variants; if your design later needs a different speed grade or package, the family shares the same die and interface, simplifying second-source qualification within the series. For a system architect clocking a 100 MHz bus (10 ns period), this leaves zero margin for address decoding, PCB trace delay, and input setup at the controller — so a 10 ns SRAM is realistically a fit for buses running at 66 MHz or slower unless the controller has a programmable wait-state generator. The 256K x 16 organization gives a 16-bit word width, which halves the pin count versus a byte-wide part for the same density — useful when the FPGA or ASIC has limited I/O banks. The parallel interface is straightforward: no clock, no command sequences — just chip enable, output enable, write enable, and the address/data bus. This simplicity is the reason asynchronous SRAM still appears in latency-critical paths where SDRAM's refresh overhead is unacceptable.","metaTitle":"Infineon CY7C1041CV33-10BAJXET 4Mbit Async SRAM, 10 ns","metaDescription":"Infineon CY7C1041CV33-10BAJXET 4Mbit asynchronous SRAM, 10 ns access time, 256K x 16, 3V-3.6V, -40°C to 125°C, 48-TFBGA.","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":"Tape & Reel (TR)","Technology":"SRAM - Asynchronous","Access Time":"10 ns","Memory Size":"4Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"48-TFBGA","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C1041","Memory Organization":"256K x 16","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"48-FBGA (7x8.5)","Write Cycle Time - Word, Page":"10ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/98b02073131aa52ac3498b86bf89b293.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1041CV33-10BAJXET/alternatives.json"},"ai":{"faq":[{"question":"Does CY7C1041CV33-10BAJXET have an equivalent or cross-reference?","answer":"The base product number CY7C1041 covers a family of density and speed variants sharing the same die and interface.
