Cypress (now Infineon) no longer manufactures the CY7C1399BL-12ZXCT in volume. For BOM lines that need this exact footprint and timing, the supply channel is independent distribution — surplus stock, new-old-stock, or broker inventory. The 28-TSSOP package is the footprint to match if evaluating alternatives. This limits the part to indoor, temperature-controlled environments — office equipment, telecom racks with active cooling, benchtop instruments, or appliance control boards. Not suitable for outdoor, automotive, or industrial enclosures where the ambient drifts outside that window.","metaTitle":"CY7C1399BL-12ZXCT SRAM, 256Kbit, 12 ns, Obsolete","metaDescription":"Infineon/Cypress CY7C1399BL-12ZXCT asynchronous SRAM, 256Kbit (32K x 8), 12 ns access time, 3V-3.6V, 28-TSOP I.","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 - Asynchronous","Access Time":"12 ns","Memory Size":"256Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"28-TSSOP (0.465\\\", 11.80mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C1399","Memory Organization":"32K x 8","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"28-TSOP I","Write Cycle Time - Word, Page":"12ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a01599d373db306f08880242de2c1d40.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1399BL-12ZXCT/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1399BL-12ZXCT obsolete?","answer":"Yes, the lifecycle status for CY7C1399BL-12ZXCT is Obsolete.
