Designed for uni-directional, depth- and width-expandable buffering, it supports programmable flags and retransmit capability, making it suitable for high-speed data acquisition, telecom line cards, and video frame buffers where deterministic latency matters. ## Obsolete — no direct replacement on record This part is officially marked as Obsolete by the manufacturer. There is no listed successor order code in the available records. For production continuity, buyers should secure inventory through independent distribution channels while date-code-proven stock remains accessible. ## 8 ns access time at 100 MHz — timing margin matters The 8 ns access time and 100 MHz clock rate are specified in the datasheet. The 45 mA maximum supply current sets the power budget.","metaTitle":"CY7C4255-10AXC Synchronous FIFO, 144K (8K x 18), 8 ns Access","metaDescription":"CY7C4255-10AXC synchronous FIFO from Infineon (Cypress) — 144K (8K x 18) memory, 100 MHz data rate, 8 ns access time, 64-LQFP, 0°C to 70°C.","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":"Tube","Function":"Synchronous","Data Rate":"100MHz","Access Time":"8ns","Memory Size":"144K (8K 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":"4.5 V ~ 5.5 V","Base Product Number":"7C4255","Operating Temperature":"0°C ~ 70°C","Retransmit Capability":"Yes","Current - Supply (Max)":"45mA","Supplier Device Package":"64-TQFP (14x14)","Programmable Flags Support":"Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5220cd0ada202f0479009a18ec460118.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C4255-10AXC obsolete?","answer":"Yes, the CY7C4255-10AXC is officially marked as Obsolete.
