It clocks at 100 MHz and delivers an 8 ns access time. For new designs, look at current-generation synchronous FIFOs from the same family or from vendors like IDT/Renesas or TI that offer pin-compatible or functionally equivalent parts in 64-LQFP. ## 5 V supply and industrial temperature — fit for legacy systems Maximum supply current is 50 mA at 100 MHz. ## Package and footprint: 64-LQFP (14x14 mm) Housed in a 64-LQFP package with a 14x14 mm body. The supplier device package is 64-TQFP (14x14).","metaTitle":"CY7C4225-10AXI Cypress 18K Sync FIFO, 100 MHz, 8 ns, 64-LQFP","metaDescription":"CY7C4225-10AXI Cypress synchronous FIFO, 18K (1K x 18), 100 MHz data rate, 8 ns access time, 5V supply, -40°C to 85°C, 64-LQFP.","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":"Tray","Function":"Synchronous","Data Rate":"100MHz","Access Time":"8ns","Memory Size":"18K (1K 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":"7C4225","Operating Temperature":"-40°C ~ 85°C","Retransmit Capability":"Yes","Current - Supply (Max)":"50mA","Supplier Device Package":"64-TQFP (14x14)","Programmable Flags Support":"Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e04889be73c539b31e9c2648be4d9d69.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C4225-10AXI/alternatives.json"},"ai":{"faq":[{"question":"What is the recommended replacement for CY7C4225-10AXI?","answer":"For a form-fit-function replacement, look at other Cypress CY7C series synchronous FIFOs with 1K x 18 depth and 100 MHz speed in 64-LQFP, or cross-reference to IDT72V series or SN74V series from TI.
