Note that this variant does not include FWFT (First-Word Fall-Through), retransmit capability, or programmable flags — the flag logic is fixed. For designs that need FWFT or custom flag thresholds, you would look at a different Cypress FIFO family member.","metaTitle":"CY7C4251V-15AXC Synchronous FIFO, 72K, 66.7 MHz, 11 ns","metaDescription":"Cypress CY7C4251V-15AXC synchronous FIFO memory: 72K (8K x 9), 66.7 MHz data rate, 11 ns access time, 3 V–3.6 V, 0°C–70°C, 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":"Tray","Function":"Synchronous","Data Rate":"66.7MHz","Access Time":"11ns","Memory Size":"72K (8K 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":"7C4251","Operating Temperature":"0°C~70°C","Retransmit Capability":"No","Current - Supply (Max)":"20mA","Supplier Device Package":"32-TQFP (7x7)","Programmable Flags Support":"No"}},"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 data rate of CY7C4251V-15AXC?","answer":"The CY7C4251V-15AXC operates at a 66.7 MHz data rate with an 11 ns access time, giving a peak throughput of 66.7 million words per second on the 9-bit bus."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C4251V-15AXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C4251V-15AXC when reusing this data.
