No last-time-buy window remains open. ## 165-ball FBGA — footprint and rework considerations The 165-ball FBGA (13x15 mm body) uses a 1.0 mm ball pitch typical of high-density SRAM packages. The supplier device package is 165-FBGA (13x15). For rework, a pre-bake at 125°C for 24 hours is standard if the floor-life window has been exceeded.","metaTitle":"Cypress CY7C1550KV18-450BZC 72Mbit DDR II+ SRAM, 450 MHz","metaDescription":"Cypress CY7C1550KV18-450BZC 72Mbit synchronous SRAM, DDR II+, 450 MHz clock, 2M x 36 organization, 165-FBGA, 0°C to 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 - Synchronous, DDR II+","Memory Size":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"450 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1550","Memory Organization":"2M x 36","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/05e092eed8677677558d6b1caff65ea0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1550KV18-450BZC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1550KV18-450BZC obsolete?","answer":"Yes, the lifecycle status is Obsolete.
