The dual-port architecture gives two independent controllers simultaneous access to the same memory array, eliminating the arbitration overhead of a multiplexed single-port design. ## 5V-only supply — check your rail before committing If your design runs on 3.3V or lower, you will need level translators on address, data, and control lines. The CY7C144-15JXC is officially obsolete per the manufacturer. Sourcing is through independent distribution channels, where inventory is fixed and finite. ## Package and footprint — 68-PLCC Housed in a 68-lead PLCC (J-Lead) package with a body size of 24.23 mm x 24.23 mm. The J-lead footprint is surface-mount but requires a PLCC socket or a reflow profile suited to the lead geometry.","metaTitle":"CY7C144-15JXC Infineon 64Kbit Dual-Port SRAM, 15 ns, 68-PLCC","metaDescription":"Infineon CY7C144-15JXC 64Kbit (8K x 8) asynchronous dual-port SRAM with 15 ns access time, 4.5V–5.5V supply, 0°C–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":"-","Package":"Tray","Technology":"SRAM - Dual Port, Asynchronous","Access Time":"15 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":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3c8fc66c7400e6b35a2961db05899272.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C144-15JXC obsolete?","answer":"Yes, the manufacturer lists CY7C144-15JXC as obsolete.
