In a synchronous FIFO, the read and write clocks run free-running; the 11 ns access time means the first word appears on the bus 11 ns after the read clock edge, giving the receiving logic a setup window of roughly 4 ns at 66.7 MHz (15 ns period minus 11 ns). That is tight but workable for 3.3 V CMOS inputs with typical 2 ns setup requirements. The 36K (4K x 9) organization suits byte-wide data paths with a parity bit — think telecom framers, DSP ping-pong buffers, or PCI target FIFOs where the extra bit carries an out-of-band flag. ## Obsolete — no direct replacement on record For existing BOM lines, sourcing runs through independent distribution — verified surplus or new-old-stock lots, quoted against an RFQ with traceability documentation. Not rated for motor drives, outdoor base stations, or under-hood automotive — those would need an industrial or automotive-grade FIFO in a wider temp package. ## Package and supply — board-fit checklist 32-TQFP (7x7 mm) surface-mount package. Maximum supply current is 20 mA. The part supports depth and width expansion (cascading multiple devices for deeper or wider buffers) and has programmable flags. No FWFT (First-Word Fall-Through) support; the first read after a write requires the 11 ns access time before valid data appears.","metaTitle":"CY7C4241V-15AXCT Synchronous FIFO, 66.7 MHz, 11 ns","metaDescription":"Infineon/Cypress CY7C4241V-15AXCT synchronous FIFO, 36K (4K x 9), 66.7 MHz data rate, 11 ns access time. 32-TQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"CY7C","Package":"Tape & Reel (TR)","Function":"Synchronous","Data Rate":"66.7MHz","Access Time":"11ns","Memory Size":"36K (4K x 9)","FWFT Support":"No","Mounting Type":"Surface Mount","Expansion Type":"Depth, Width","Package / Case":"32-TQFP","Product Status":"Obsolete","Bus Directional":"Uni-Directional","lifecycle_stage":"eol_hot","Voltage - Supply":"3 V ~ 3.6 V","Base Product Number":"7C4241","Operating Temperature":"0°C~70°C","Retransmit Capability":"No","Current - Supply (Max)":"20mA","Supplier Device Package":"32-TQFP (7x7)","Programmable Flags Support":"Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/06df22868d8a34fd15e9034e48ed2c13.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the direct replacement for CY7C4241V-15AXCT?","answer":"No direct replacement is listed in the official record.
