The part supports depth and width expansion, includes programmable flags, and is uni-directional with no retransmit or FWFT support. At 1K x 9, the memory depth is shallow. This FIFO is sized for small buffer applications — think data packet alignment, rate-matching between a fast bus and a slower peripheral, or temporary storage in a pipeline. If your design needs more than 9K bits of buffering, you will need to cascade multiple devices or look at a deeper FIFO. The 35 mA maximum supply current is modest for a 5 V synchronous part.","metaTitle":"Cypress CY7C4221-15AXCT Synchronous FIFO, 66.7MHz, 10ns","metaDescription":"Cypress CY7C4221-15AXCT synchronous FIFO, 9K (1K x 9), 66.7 MHz data rate, 10 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":"10ns","Memory Size":"9K (1K 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":"4.5 V ~ 5.5 V","Base Product Number":"7C4221","Operating Temperature":"0°C~70°C","Retransmit Capability":"No","Current - Supply (Max)":"35mA","Supplier Device Package":"32-TQFP (7x7)","Programmable Flags Support":"Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.4700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b0115a44e89566724ee3f49375c67cf8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C4221-15AXCT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C4221-15AXCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C4221-15AXCT when reusing this data.
