The part supports depth and width expansion, includes programmable flags and retransmit capability, and is uni-directional. Typical applications include buffering in telecom, networking, and DSP datapaths where a synchronous handshake and moderate depth are needed. ## 11 ns access time — read-cycle margin At a 66.7 MHz clock (15 ns period), this leaves 4 ns of setup margin for the host controller — enough for most 3.3 V logic families, but tight if the board has long traces or multiple loads. The 30 mA maximum supply current gives a rough power budget: at 3.3 V, about 100 mW worst-case, so no special thermal management is needed in the 64-TQFP package.","metaTitle":"Cypress CY7C4205V-15ASXCT Synchronous FIFO, 66.7 MHz, 11 ns","metaDescription":"Cypress CY7C4205V-15ASXCT synchronous FIFO: 66.7 MHz data rate, 11 ns access time, 4.5 Kbit (256 x 18), 3 V–3.6 V supply, 64-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":"4.5K (256 x 18)","FWFT Support":"No","Mounting Type":"Surface Mount","Expansion Type":"Depth, Width","Package / Case":"64-LQFP","Product Status":"Obsolete","Bus Directional":"Uni-Directional","lifecycle_stage":"eol_hot","Voltage - Supply":"3 V ~ 3.6 V","Base Product Number":"7C4205","Operating Temperature":"0°C~70°C","Retransmit Capability":"Yes","Current - Supply (Max)":"30mA","Supplier Device Package":"64-TQFP (10x10)","Programmable Flags Support":"Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fc37a4fdc03d6700d19a5428d2f59d7c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C4205V-15ASXCT obsolete?","answer":"Yes, the CY7C4205V-15ASXCT is listed as Obsolete.
