The 68-lead PLCC with J-leads (24.23 mm x 24.23 mm body) is a surface-mount package that sits in a socket or solders directly to the board. J-leads are forgiving for hand rework compared to QFP gull-wing leads. ## Obsolete — the sourcing picture No further factory orders are being accepted; no last-time-buy window remains open.","metaTitle":"CY7C144E-55JXCT Infineon 64Kbit Dual-Port SRAM, 55 ns","metaDescription":"Infineon CY7C144E-55JXCT 64Kbit dual-port asynchronous SRAM, 8K x 8 organization, 55 ns access time, 4.5V-5.5V supply, 68-PLCC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Technology":"SRAM - Dual Port, Asynchronous","Access Time":"55 ns","Memory Size":"64Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"68-LCC (J-Lead)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C144","Memory Organization":"8K x 8","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"68-PLCC (24.23x24.23)","Write Cycle Time - Word, Page":"55ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0c592dfbc5160a28d9f87bcc6698f161.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C144E-55JXCT/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C144E-55JXCT obsolete?","answer":"Yes, Infineon lists the CY7C144E-55JXCT as obsolete.
