It clocks at 100 MHz with an 8 ns access time, meaning the read pointer can present new data every clock cycle at full speed — no wait states for the downstream logic if the pipeline is kept full. The 30 mA max supply current is low enough that a shared 3.3 V rail can feed it without a dedicated regulator, but the 0.5 mm pitch on the 64-LQFP demands a controlled reflow profile — check the MSL before you place it, or it popcorns. Infineon lists the CY7C4275V-10ASC as obsolete. ## Depth/width expandable with programmable flags The CY7C4275V-10ASC supports expansion in both depth and width — multiple devices can cascade without external logic, which simplifies scaling the buffer for wider data paths or deeper queues. The programmable flags let the system set almost-full and almost-empty thresholds, so the controller can pace reads and writes before the FIFO stalls. Retransmit capability means the FIFO can re-send data from a previous read pointer position — useful in packet-based systems where a dropped word triggers a retry without re-loading the entire buffer from the source.","metaTitle":"Infineon CY7C4275V-10ASC synchronous FIFO, 576K, 100 MHz","metaDescription":"Infineon CY7C4275V-10ASC synchronous FIFO, 576K (32K x 18), 100 MHz, 8 ns access, 3.3 V, 64-LQFP, 0-70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"title":"CY7C4275V-10ASC","Series":"CY7C","Package":"Bag","Function":"Synchronous","Data Rate":"100MHz","Access Time":"8ns","Memory Size":"576K (32K x 18)","FWFT Support":"No","Mounting Type":"Surface Mount","Expansion Type":"Depth, Width","Package / Case":"64-LQFP","Bus Directional":"Uni-Directional","lifecycle_stage":"eol_hot","Voltage - Supply":"3 V ~ 3.6 V","Base Product Number":"7C4275","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/db77559a1966cb6b7d6c655a93706930.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package does the CY7C4275V-10ASC use?","answer":"It is supplied in a 64-LQFP package with a 64-TQFP (10x10 mm) footprint.
