It is designed for uni-directional buffering in data-path applications where the read and write clocks run synchronously. At 100 MHz the FIFO supports a sustained data rate of 100 million words per second. The 8 ns access time from the rising clock edge to valid data on the bus sets the setup margin for the receiving device. Cypress has discontinued production; there is no last-time-buy window open. New designs should not target this part. ## Package and handling notes for the 32-PLCC The 32-LCC (J-Lead) package — supplier device package 32-PLCC (11.43x13.97) — is a legacy surface-mount footprint. J-leads require a reflow profile with a gradual ramp to avoid solder wicking up the lead bend; the PLCC body also traps flux residue, so a post-reflow clean is recommended for high-reliability assemblies. The part ships in Tube (not Tape & Reel), which affects pick-and-place feeder setup.","metaTitle":"CY7C4261-10JXI synchronous FIFO, 100 MHz, 8 ns","metaDescription":"CY7C4261-10JXI synchronous FIFO from Cypress, 100 MHz data rate, 8 ns access time, 144K (16K x 9) memory, 32-PLCC, -40°C to 85°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 (16K x 9)","FWFT Support":"No","Mounting Type":"Surface Mount","Expansion Type":"Depth, Width","Package / Case":"32-LCC (J-Lead)","Product Status":"Obsolete","Bus Directional":"Uni-Directional","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5 V ~ 5.5 V","Base Product Number":"7C4261","Operating Temperature":"-40°C~85°C","Retransmit Capability":"No","Current - Supply (Max)":"40mA","Supplier Device Package":"32-PLCC (11.43x13.97)","Programmable Flags Support":"Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$22.0000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a8a680452318e888104df61f5aefff6a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C4261-10JXI obsolete?","answer":"Yes, the CY7C4261-10JXI is officially Obsolete per the manufacturer's lifecycle status.
