It is a surface-mount package that can be socketed or soldered. The J-Lead form factor is less tolerant of thermal cycling than gull-wing leads; for high-reliability designs, consider a socket or confirm the board's CTE match. The package is not pin-compatible with 68-pin SOJ or TSOP-II footprints. ## Obsolete — sourcing strategy Infineon lists the CY7C138-25JXI as obsolete.","metaTitle":"Infineon CY7C138-25JXI 32Kbit Dual-Port SRAM, 25 ns","metaDescription":"Infineon CY7C138-25JXI 32Kbit (4K x 8) asynchronous dual-port SRAM, 25 ns access time, parallel interface, 4.5V–5.5V supply, -40°C to 85°C, 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":"Tube","Technology":"SRAM - Dual Port, Asynchronous","Access Time":"25 ns","Memory Size":"32Kbit","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":"CY7C138","Memory Organization":"4K x 8","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"68-PLCC (24.23x24.23)","Write Cycle Time - Word, Page":"25ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2313b9dd3709aa6f14c70932c0a78a05.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C138-25JXI/alternatives.json"},"ai":{"faq":[{"question":"What is the package type for CY7C138-25JXI?","answer":"68-lead PLCC with J-Leads (68-LCC J-Lead, supplier package 68-PLCC 24.23x24.23 mm).
