The 9-bit width includes a parity bit per word — useful for data integrity in buffered pipelines where the extra bit carries a check or tag. ## 32-PLCC package and board-fit Housed in a 32-lead PLCC with J-leads (32-LCC), the supplier device package is 32-PLCC measuring 11.43 x 13.97 mm. Surface-mount only — the J-lead footprint is standard for PLCC sockets or direct solder. ## Feature set: programmable flags, no retransmit Supports programmable flags for almost-empty/almost-full thresholds, which allows the system to pace reads and writes before the FIFO hits its boundaries. No FWFT (First-Word Fall-Through) and no retransmit capability — the read pointer advances on each read clock, and there is no mechanism to rewind without a full reset. Expansion is supported in both depth and width, so multiple devices can cascade for larger buffers.","metaTitle":"CY7C4271V-10JC Synchronous FIFO, 288K, 100MHz, 32-PLCC","metaDescription":"CY7C4271V-10JC synchronous FIFO, 288K (32K x 9), 100 MHz, 8 ns access time, 3.3 V, 32-PLCC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"title":"CY7C4271V-10JC","Series":"CY7C","Package":"Tray","Function":"Synchronous","Data Rate":"100MHz","Access Time":"8ns","Memory Size":"288K (32K x 9)","FWFT Support":"No","Mounting Type":"Surface Mount","Expansion Type":"Depth, Width","Package / Case":"32-LCC (J-Lead)","Bus Directional":"Uni-Directional","lifecycle_stage":"eol_hot","Voltage - Supply":"3 V ~ 3.6 V","Base Product Number":"7C4271","Operating Temperature":"0°C~70°C","Retransmit Capability":"No","Current - Supply (Max)":"25mA","Supplier Device Package":"32-PLCC (11.43x13.97)","Programmable Flags Support":"Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to CY7C4271V-10JC in this memory family?","answer":"The CY7C series includes other synchronous FIFOs, but pin compatibility and timing must be verified against the specific BOM position.
