The retransmit capability lets the controller reset the read pointer back to the beginning of the stored data without a full flush, useful in packet-based systems where a failed transmission needs a replay from the buffer. Housed in a 32-PLCC (J-Lead) surface-mount package, this part uses the legacy PLCC footprint — verify your board's land pattern matches the 11.43x13.97 mm body. ## Supply and current budget Maximum supply current is 65 mA.","metaTitle":"CY7C419-15JXC Asynchronous FIFO, 2.25K, 15ns, 32-PLCC","metaDescription":"Cypress CY7C419-15JXC asynchronous FIFO memory, 2.25K (256x9), 15ns access time, 50MHz data rate, 32-PLCC, 0-70°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":"Asynchronous","Data Rate":"50MHz","Access Time":"15ns","Memory Size":"2.25K (256 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":"7C419","Operating Temperature":"0°C ~ 70°C","Retransmit Capability":"Yes","Current - Supply (Max)":"65mA","Supplier Device Package":"32-PLCC (11.43x13.97)","Programmable Flags Support":"No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/81fe1ebe514e502a4e182e51ce1fc707.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy CY7C419-15JXC?","answer":"The CY7C419-15JXC is obsolete and not available through the authorized factory channel.
